We analyse anchored hybrid enrichment data from densely sampled tribes and subfamilies of Notodontidae (Prominent Moths). Notodontidae are monophyletic except for an assemblage of genera related to Thacona Walker (=Scrancia Holland), which had been recognized at either the tribal or subfamilial rank within Notodontidae. We elevate and re-describe Scranciidae stat. nov. as a family distinct from the six currently recognized noctuoid families (Noctuidae, Erebidae, Euteliidae, Nolidae, Notodontidae and Oenosandridae). Scranciidae include 22 genera comprising approximately 100 species—distributed in Africa, Asia and Australia. We re-interpret morphological synapomorphies previously proposed for Notodontidae (including Scranciidae) and for the trifid Noctuoidea more broadly. Deep-level relationships within Noctuoidea are not well resolved outside the clade comprising the four quadrifid families (Noctuidae, Erebidae, Euteliidae and Nolidae). The phylogenetic position of Scranciidae relative to Notodontidae, Oenosandridae and the quadrifids varied markedly depending on data type (amino acid vs. nucleotide) and analytical framework (maximum likelihood, multi-species coalescent and parsimony). We discuss the possible roles of missing data and short branch lengths in resolving the placement of Scranciidae. In the topology best supported by the most available data, Scranciidae are sister to the remaining Noctuoidea, highlighting their phylogenetic significance. We provide a provisional list of the genera included in Scranciidae.

我们分析了取样密集的飞蛾科(Notodontidae)部落和亚科的锚定杂交富集数据。除了与 Thacona Walker(=Scrancia Holland)有关的一个属的集合之外,Notodontidae 是单系的。我们将 Scranciidae 升格并重新描述为一个科,与目前公认的 6 个夜蛾科(Noctuidae、Erebidae、Euteliidae、Nolidae、Notodontidae 和 Oenosandridae)不同。Scranciidae 包括 22 属,约 100 种,分布于非洲、亚洲和澳大利亚。我们重新解释了之前提出的Notodontidae(包括Scranciidae)和更广义的三叉Noctuoidea的形态学同形异构。Noctuoidea内部的深层关系在由四个四裂科(Noctuidae、Erebidae、Euteliidae和Nolidae)组成的支系之外并没有得到很好的解决。根据数据类型(氨基酸与核苷酸)和分析框架(最大似然法、多物种聚合法和解析法)的不同,Scranciidae相对于Notodontidae、Oenosandridae和四叉科的系统发生位置也有明显差异。我们讨论了缺失数据和短分支长度在确定 Scranciidae 的位置时可能发挥的作用。在现有数据最能支持的拓扑结构中,Scranciidae 是其余 Noctuoidea 的姊妹,这突显了它们在系统发育上的重要性。我们提供了一份包含在 Scranciidae 中的属的临时列表。

The complex and dynamic history of the Anatolian Peninsula during the Pleistocene set the stage for species diversification. However, the evolutionary history of biodiversity in the region is shrouded by the challenges of studying species divergence in the recent, dynamic past. Here, we study the Poecilimon bosphoricus (PB) species group to understand how the bush crickets' diversification and the regions' complex history are coupled. Specifically, using sequences of two mitochondrial and two nuclear gene segments from over 500 individuals for a comprehensive set of taxa with extensive geographic sampling, we infer the phylogenetic and geographic setting of species divergence. In addition, we use the molecular data to examine hypothesized species boundaries that were defined morphologically. Our analyses of the timing of divergence confirm the recent origin of the PB complex, indicating its diversification coincided with the dynamic geology and climate of the Pleistocene. Moreover, the geography of divergence suggests a history of fragmentation followed by admixture of populations, suggestive of a ring species. However, the evolutionary history based on genetic divergence conflicts with morphologically defined species boundaries raising the prospects that incipient species divergences may be relatively ephemeral. As such, the morphological differences observed in the PB complex may not to be sufficient to have prevented homogenizing gene flow in the past. Alternatively, with the recent origin of the complex, the lack of time for lineage sorting may underlie the discord between morphological species boundaries and genetic differentiation. Under either hypothesis, geography—not taxonomy—is the best predictor of genetic divergence.

安纳托利亚半岛在更新世期间复杂多变的历史为物种多样化奠定了基础。然而,该地区生物多样性的进化史却被研究近代动态历史中物种分化的挑战所掩盖。在这里,我们研究了Poecilimon bosphoricus(PB)物种群,以了解丛林蟋蟀的物种多样化与该地区复杂的历史是如何结合在一起的。具体来说,我们利用来自 500 多个个体的两个线粒体基因片段和两个核基因片段的序列,通过广泛的地理取样,对物种分化的系统发育和地理环境进行了推断。此外,我们还利用分子数据研究了从形态学角度界定的假定物种边界。我们对物种分化时间的分析证实了 PB 复合体起源于近期,表明其分化与更新世的动态地质和气候相吻合。此外,分化的地理位置表明,其种群经历了先破碎后混杂的历史,这表明它是一个环状物种。然而,基于遗传分化的进化史与形态学上确定的物种边界相冲突,这就使得物种分化的萌芽可能相对短暂。因此,在 PB 复合体中观察到的形态差异可能不足以阻止过去的同源基因流动。或者,由于该复合体起源较晚,缺乏进行世系分类的时间,这可能是形态上的物种边界与遗传分化不一致的原因。无论是哪种假设,地理而非分类学都是预测基因分化的最佳指标。

Rapid species radiations present difficulties for phylogenetic reconstruction due to lack of phylogenetic information and processes such as deep coalescence/incomplete lineage sorting and hybridization. Phylogenomic data can overcome some of these difficulties. In this study, we use anchored hybrid enrichment (AHE) nuclear phylogenomic data and mitochondrial genomes recovered from AHE bycatch with several concatenated and coalescent approaches to reconstruct the poorly resolved radiation of the New Zealand cicada species in the genera Kikihia Dugdale and Maoricicada Dugdale. Compared with previous studies using only three to five Sanger-sequenced genes, we find increased resolution across our phylogenies, but several branches remain unresolved due to topological conflict among genes. Some nodes that are strongly supported by traditional support measures like bootstraps and posterior probabilities still show significant gene and site concordance conflict. In addition, we find strong mito-nuclear discordance; likely the result of interspecific hybridization events in the evolutionary history of Kikihia and Maoricicada.

由于缺乏系统发育信息以及深度凝聚/不完全系分类和杂交等过程,快速物种辐射给系统发育重建带来了困难。系统发生组数据可以克服其中一些困难。在本研究中,我们利用锚定杂交富集(AHE)核系统发生组数据和从 AHE 副渔获物中回收的线粒体基因组,并采用几种连接和聚合方法,重建了新西兰蝉属 Kikihia Dugdale 和 Maoricicada Dugdale 的辐射解析度较低的蝉种。与之前仅使用三到五个桑格测序基因的研究相比,我们发现我们的系统发生的分辨率有所提高,但由于基因间的拓扑冲突,一些分支仍未得到解决。一些通过传统支持度量(如引导和后验概率)得到强有力支持的节点仍然显示出明显的基因和位点一致性冲突。此外,我们还发现了强烈的有丝分裂-核分裂不一致现象;这可能是 Kikihia 和 Maoricicada 进化史中种间杂交事件的结果。

Phylogenetics, historical biogeography and molecular species delimitation of Chanohirata (Hemiptera: Cicadellidae: Deltocephalinae: Penthimiini) Chanohirata 的系统发育、历史生物地理学和分子物种划分(半翅目:蝉科:Deltocephalinae:Penthimiini)

The genus Chanohirata Hayashi & Machida, including the herein synonymized monotypic genus Reticuluma Cheng & Li, is the second most speciose genus in the tribe Penthimiini after Penthimia Germar and is almost exclusively endemic to China. This study presents the first phylogeny of Chanohirata based on three mitochondrial markers (cytochrome c oxidase subunit I and II and 16S ribosomal RNA) and one nuclear fragment (28S ribosomal RNA). Reticuluma syn. n. is recovered nested within Chanohirata with strong support. Reticuluma is, therefore, proposed as a junior synonym of Chanohirata, and a new combination is proposed: Chanohirata citrana (Cheng & Li) comb. n. Molecular species delimitation analyses were conducted by combining six molecular delimitation methods with morphological evidence. The results of the species delimitation analyses confirm the status of eight described species of Chanohirata and support the recognition of three new species: Chanohirata cornicula Wang & Zhang sp. n., Chanohirata elongata Wang & Zhang sp. n. and Chanohirata serrata Wang & Zhang sp. n. Molecular dating and biogeographic analyses suggest that Chanohirata likely originated during the late Eocene in southern China. During the late Miocene to early Pleistocene, the uplift of the Himalayas and Tibetan Plateau and climatic oscillations probably triggered several dispersal and vicariance events in Chanohirata lineages, leading to most speciation events.

Chanohirata Hayashi & Machida属,包括在此同义的单型属Reticuluma Cheng & Li,是仅次于Penthimia Germar的Penthimiini族中物种第二多的属,几乎完全为中国特有。本研究基于三个线粒体标记(细胞色素 c 氧化酶亚单位 I 和 II 以及 16S 核糖体 RNA)和一个核片段(28S 核糖体 RNA),首次提出了 Chanohirata 的系统发生。Reticuluma syn. n. 在 Chanohirata 中的嵌套得到了有力的支持。因此,建议将 Reticuluma 作为 Chanohirata 的低级异名,并提出一个新的组合:结合六种分子定界方法和形态学证据,进行了分子物种定界分析。物种定界分析的结果确认了 8 个已描述的 Chanohirata 种的地位,并支持确认 3 个新种:分子年代学和生物地理学分析表明,Chanohirata 很可能起源于中国南方的始新世晚期。在中新世晚期至更新世早期,喜马拉雅山和青藏高原的隆起以及气候振荡可能引发了Chanohirata种系的多次扩散和沧海桑田事件,导致了大多数物种的分化。

Phylogenetic reconstruction of Corydioidea (Dictyoptera: Blattodea) provides new insights on the placement of Latindiinae and supports the proposal of the new subfamily Ctenoneurinae 蝶形目(双翅目:蜚蠊科)的系统发育重建为 Latindiinae 的定位提供了新的见解,并支持了 Ctenoneurinae 新亚科的提议

Representatives of the cockroach superfamily Corydioidea are less sampled than members of the two other cockroach superfamilies (Blaberoidea and Blattoidea) due to the difficulty of collecting them in the field, accentuated by a general lack of knowledge on their biology. Their evolutionary relationships have not yet been investigated with a relevant sampling and are therefore poorly known. Here, we assess the phylogenetic relationships of 35 Corydioidea species with mitochondrial genomes and two nuclear gene fragments. Our sampling for Corydiidae comprises Corydiinae and Euthyrrhaphinae representatives, whereas our sampling for the remaining Corydioidea includes species belonging to genera Beybienkonus Qiu, Wang and Che, Compsodes Hebard, Ctenoneura Hanitsch and Nocticola Bolívar. We further infer their divergence times with molecular dating analyses relying on five fossil calibrations. We also carry out reconstructions of ancestral character states for 11 phenotypic and one biological traits. Our results recover two major Corydioidea clades, one consisting solely of Corydiidae (except Latindiinae) and the other of all remaining Corydioidea taxa. Based on the results of phylogenetic analyses, an updated classification of extant Corydioidea is proposed, where Latindiinae Handlirsch stat.rev. and Ctenoneurinae Qiu and Che, subfam.nov. are assigned to the family Nocticolidae Bolívar sensu nov. A new genus Pseudoeupolyphaga Qiu and Che, gen.nov. is also established within Corydiinae. Both the origin of crown Corydioidea and the divergence of the two major lineages are estimated to have occurred during the Triassic–Jurassic boundary. Ancestral character state reconstruction analyses also suggest an adaptive relationship between phenotypic characteristics and habitat preferences.

与其他两个蟑螂超科(Blaberoidea 和 Blattoidea)的成员相比,蜚蠊超科(Corydioidea)的代表蟑螂取样较少,这是因为在野外采集它们很困难,而且对它们的生物学知识普遍缺乏了解。它们的进化关系尚未通过相关取样进行研究,因此知之甚少。在此,我们利用线粒体基因组和两个核基因片段评估了 35 个堇菜科物种的系统发育关系。我们对堇菜科(Corydiidae)的取样包括堇菜科(Corydiinae)和堇菜属(Euthyrrhaphinae)的代表物种,而我们对其余堇菜科(Corydioidea)的取样包括属于Beybienkonus Qiu、Wang和Che属,Compsodes Hebard属,Ctenoneura Hanitsch属和Nocticola Bolívar属的物种。我们根据五种化石的校准,通过分子测年分析进一步推断了它们的分化时间。我们还重建了 11 种表型特征和 1 种生物特征的祖先特征状态。我们的研究结果发现了两个主要的 Corydioidea 支系,一个支系仅由 Corydiidae(Latindiinae 除外)组成,另一个支系则由所有剩余的 Corydioidea 类群组成。根据系统发育分析的结果,提出了现存 Corydioidea 的最新分类,其中 Latindiinae Handlirsch stat.rev. 和 Ctenoneurinae Qiu and Che, subfam.nov. 被归入 Nocticolidae Bolívar sensu nov.科。新属 Pseudoeupolyphaga Qiu and Che,gen.nov. 也在 Corydiinae 内建立。据估计,冠毛目(Corydioidea)的起源和两大支系的分化都发生在三叠纪-侏罗纪边界。祖先特征状态重建分析也表明了表型特征与生境偏好之间的适应关系。

The Miltogramminae (Diptera: Sarcophagidae) includes ~600 species across >40 genera, which constitute ~20% of global Sarcophagidae. While molecular phylogenetic hypotheses have been produced for this group, critical problems persist, including the presence of paraphyletic genera, uncertain relationships between genera, a bias of sampling towards Palaearctic taxa, and low support for many branches. The present study remedies these issues through the application of Anchored Hybrid Enrichment (AHE) to a sample including ~60% of the currently recognised genera (16% of known species) representing all biogeographic regions except the Neotropical. An alignment of 1,281 concatenated loci was analysed with maximum likelihood (RAxML, IQ-TREE), Bayesian inference (ExaBayes) and coalescent-based approaches (ASTRAL, SVDquartets), which resulted in highly supported and concordant topologies, providing unprecedented insight into the relationships of this subfamily of flesh flies, allowing a major update to miltogrammine classification. The AHE phylogenetic hypothesis supports the monophyly of a large proportion of genera. The monophyly of Metopia Meigen is restored by synonymy with Aenigmetopia Malloch, syn.n. To achieve monophyly of Miltogramma Meigen, eight species are transferred from Pterella Robineau-Desvoidy. The genus Pterella is shown to be paraphyletic in its current circumscription, and to restore generic monophyly Pterella is restricted to contain only Pt. grisea (Meigen). Erioprocta Enderlein, stat.rev., is resurrected. The genus Senotainia Macquart is reconstructed as paraphyletic. The monotypic genus Metopodia Brauer & Bergenstamm is synonymised with Taxigramma Macquart, syn.n. In light of our phylogenetic hypotheses, a new Miltogramminae tribal classification is proposed, composed of six tribes.

Miltogramminae(双翅目: Sarcophagidae)包括 40 个属的约 600 个物种,占全球 Sarcophagidae 的约 20%。虽然已经对该类群提出了分子系统发育假说,但关键问题依然存在,包括存在旁支属、属间关系不确定、采样偏向古北区类群以及许多分支的支持率较低。本研究通过应用锚定杂交富集(AHE)技术,对代表除新热带地区以外所有生物地理区域的约 60% 的目前已确认属(16% 的已知物种)进行取样,解决了这些问题。利用最大似然法(RAxML、IQ-TREE)、贝叶斯推断法(ExaBayes)和基于聚合的方法(ASTRAL、SVDquartets)对 1,281 个连接位点的排列进行了分析,得出了高度支持和一致的拓扑结构,为深入了解肉蝇亚科的关系提供了前所未有的视角,从而对小米蝇的分类进行了重大更新。AHE 系统发育假说支持大部分属的单系性。Metopia Meigen 的单系性通过与 Aenigmetopia Malloch,syn.n.的同义关系得以恢复。为了实现 Miltogramma Meigen 的单系性,从 Pterella Robineau-Desvoidy 转来了 8 个种。Pterella 属在目前的圈定中被证明为旁系,为了恢复属的单系性,Pterella 属被限制为只包含 Pt. Grisea (Meigen)。Erioprocta Enderlein, stat.rev. 被恢复。Senotainia Macquart 属被重建为旁系。单型属 Metopodia Brauer & Bergenstamm 与 Taxigramma Macquart 同义。

Gall wasps (Hymenoptera: Cynipidae) comprise 13 distinct tribes whose interrelationships remain incompletely understood. Recent analyses of ultra-conserved elements (UCEs) represent the first attempt at resolving these relationships using phylogenomics. Here, we present the first analysis based on protein-coding sequences from genome and transcriptome assemblies. Unlike UCEs, these data allow more sophisticated substitution models, which can potentially resolve issues with long-branch attraction. We include data for 37 cynipoid species, including two tribes missing in the UCE analysis: Aylacini (s. str.) and Qwaqwaiini. Our results confirm the UCE result that Cynipidae are not monophyletic. Specifically, the Paraulacini and Diplolepidini + Pediaspidini fall outside a core clade (Cynipidae s. str.), which is more closely related to the insect-parasitic Figitidae, and this result is robust to the exclusion of long-branch taxa that could mislead the analysis. Given this, we here divide the Cynipidae into three families: the Paraulacidae stat. prom., Diplolepididae stat. prom. and Cynipidae (s. str.). Our results suggest that the Eschatocerini are the sister group of the remaining Cynipidae (s. str.). Within the Cynipidae (s. str.), the Aylacini (s. str.) are more closely related to oak gall wasps (Cynipini) and some of their inquilines (Ceroptresini) than to other herb gallers (Aulacideini and Phanacidini), and the Qwaqwaiini likely form a clade together with Synergini (s. str.) and Rhoophilini. Several alternative scenarios for the evolution of cynipid life histories are compatible with the relationships suggested by our analysis, but all are complex and require multiple shifts among parasitoids, inquilines and gall inducers.

瘿蜂(膜翅目:瘿蜂科)由 13 个不同的支系组成,它们之间的相互关系仍然不完全清楚。最近对超保守元素(UCEs)的分析是利用系统发生组学解决这些关系的首次尝试。在这里,我们首次基于基因组和转录组组装的蛋白质编码序列进行了分析。与 UCE 不同,这些数据可以建立更复杂的替代模型,从而有可能解决长分支吸引的问题。我们纳入了 37 个犬齿目物种的数据,其中包括两个在 UCE 分析中缺失的部族:Aylacini (s. str.) 和 Qwaqwaiini。我们的结果证实了 UCE 的结果,即鲤形目(Cynipidae)不是单系的。具体地说,Paraulacini 和 Diplolepidini + Pediaspidini 位于核心支系(Cynipidae s. str.)之外,与昆虫寄生的 Figitidae 关系更为密切。有鉴于此,我们在此将鲤科(Cynipidae)分为三科:Paraulacidae stat.我们的研究结果表明,Eschatocerini 是其余 Cynipidae(s. str.)的姊妹群。在Cynipidae(s. str.)中,Aylacini(s. str.)与橡树瘿蜂(Cynipini)及其一些内喙蜂(Ceroptresini)的亲缘关系比与其他草本瘿蜂(Aulacideini和Phanacidini)的亲缘关系更近,Qwaqwaiini可能与Synergini(s. str.)和Rhoophilini组成一个支系。鹤虱生活史进化的几种替代方案与我们的分析所提出的关系是一致的,但所有方案都很复杂,需要寄生虫、绻虫和虫瘿诱导体之间的多重转变。

Generic relationships within the parasitoid wasp subfamily Braconinae are assessed based on a molecular phylogenetic analysis of four gene fragments: mitochondrial cytochrome c oxidase subunit I, 16S rDNA, nuclear 28S D2-D3 rDNA and elongation factor 1-alpha. Our results support the recognition of Aphrastobraconini, Braconini and Coeloidini plus three new tribes: Compsobraconini tribus nov., Tropobraconini tribus nov. and Virgulibraconini tribus nov. The first of these new tribes is restricted to the New World; the second includes the Old World genera Tropobracon Cameron, Trispinaria Quicke and Grangerbracon Samartsev and Belokobylskij and possibly others, whereas the third comprises the Australian genus Virgulibracon Quicke, plus several other described and undescribed Australian genera. Consistent placement of Amyosoma Viereck with members of the Virgulibraconini tribus nov. is discussed, whereas Amyosoma is left currently unplaced. A preliminary key to tribes is presented, and the characters used to differentiate between Aphrastobraconini and Braconini are revised. Megacoeloides Quicke was never recovered with Coeloides, the type genus of Coeloidini, so it is treated as Braconinae incertae sedis. By combining molecular and morphological traits, nearly all valid genera are assigned to tribes, and the possible relationships of the remainder are discussed. Alienoclypeus Shenefelt, 1978 is synonymised with Atanycolus Förster, 1862 (Atanycolus insolitus (Shenefelt) comb. nov.). Several new genera have been revealed and will be described elsewhere.

While new species of termites are described every year, the description of species distant from every known termite species is rare. In this paper, we describe one such species, Engelitermes zambo sp.n., an African Termitidae belonging to an entirely new lineage of termites for which we create a new subfamily, Engelitermitinae subfam.n. The subfamily status of Engelitermitinae was supported by termite phylogenetic trees, including sequences from the four existing samples of E. zambo sp.n., which, albeit with low bootstrap supports, placed Engelitermes gen.n. on a long branch sister to Forficulitermes, the two of which formed the sister group of a clade comprising Cubitermitinae, Nasutitermitinae, Syntermitinae and all other Termitinae. The sister relationship between Engelitermes gen.n. and Forficulitermes is further supported by the similar gut structure of their workers. In contrast, the soldiers of Engelitermes gen.n. resemble those of Cephalotermes. Our phylogenetic analyses, including all clades of Termitinae, call for a global taxonomic revision of the Termitinae subfamily names. Finally, our study highlights that new unique termite lineages are still awaiting to be described.

虽然每年都有新的白蚁物种被描述,但与每一种已知白蚁物种相距甚远的物种描述却很少见。在本文中,我们描述了一个这样的物种,Engelitermes zambo sp.n,这是一个非洲白蚁科,属于一个全新的白蚁谱系,我们为其创建了一个新的亚科,Engelitelitinae亚科。Engelitelmininae的亚科地位得到了白蚁系统发育树的支持,包括来自E.zambo sp.n的四个现有样本的序列,尽管具有较低的自举支持,但将Engelitermes gen.n.放在Forficulitermes的一个长分支姐妹上,这两个分支形成了一个分支的姐妹群,该分支包括Cubitermitinae、Nasutitermtinae、Syntermtinae和所有其他Termitinae。Engelitermes gen.n.和Forficulitermes之间的姐妹关系进一步得到了其工人相似肠道结构的支持。相比之下,Engelitermes gen.的士兵与Cephalotermes的士兵相似。我们的系统发育分析,包括白蚁亚科的所有分支,呼吁对白蚁亚科名称进行全球分类修订。最后,我们的研究强调,新的独特白蚁谱系仍有待描述。

<p>With 74 genera and subgenera and approximately 740 species, Saprininae represent one of the largest subfamilies of Histeridae (Coleoptera: Histeroidea). Here, we present a phylogenetic hypothesis for Saprininae based on comprehensive taxonomic sampling. This is the first phylogenetic study combining molecular and morphological approaches (cytochrome <i>c</i> oxidase subunit 1, 18S ribosomal RNA and 93 morphological characters). As a result, we propose a new classification; five new tribes are erected: <b>Myrmetini</b> Portevin <b>stat. and sens. nov.</b>; <b>Euspilotini</b> Lackner, <b>trib. nov.</b>; <b>Eremosaprinini</b> Lackner, <b>trib. nov.</b>; <b>Saprinini</b> Blanchard, <b>sens. nov.</b>; and <b>Hypocaccini</b> Lackner, <b>trib. nov</b>. Additional nomenclatural acts are as follows: <i>Chelyoxenus</i> Hubbard is downgraded to a subgenus of <i>Geomysaprinus</i> Ross, thus <i>Geomysaprinus</i> (<i>Chelyoxenus</i>) <b>stat. nov.</b>, <i>Nessus</i> Reichardt is transferred from a subgenus of <i>Hypocaccus</i> C. Thomson to a subgenus of <i>Hypocacculus</i> Bickhardt, thus <i>Hypocacculus</i> (<i>Nessus</i>) <b>stat. rest.</b> The following taxa <i>Paraphilothis</i> Vienna, <i>Styphrus</i> Motschulsky, <i>Xerosaprinus</i> Wenzel, <i>Lophobregmus</i> Wenzel, <i>Vastosaprinus</i> Wenzel, <i>Auchmosaprinus</i> Wenzel, <i>Hemisaprinus</i> Kryzhanovskij & Reichardt, <i>Reichardtia</i> Wenzel and <i>Australopachylopus</i> Lackner & Leschen are all downgraded into subgenera of <i>Saprinus</i> Erichson. Thus, <i>Saprinus</i> (<i>Paraphilothis</i>) <b>stat. nov.</b>, <i>Saprinus</i> (<i>Styphrus</i>) <b>stat. nov.</b>, <i>Saprinus</i> (<i>Xerosaprinus</i>) <b>stat. nov.</b>, <i>Saprinus</i> (<i>Vastosaprinus</i>) <b>stat. nov.</b>, <i>Saprinus</i> (<i>Auchmosaprinus</i>) <b>stat. nov.</b>, <i>Saprinus</i> (<i>Lophobregmus</i>) <b>stat. nov.</b>, <i>Saprinus</i> (<i>Hemisaprinus</i>) <b>stat. rest.</b>, <i>Saprinus</i> (<i>Reichardtia</i>) <b>stat. nov.</b>, <i>Saprinus</i> (<i>Australopachylopus</i>) <b>stat. nov.</b> A new genus, <i>Paraxenus</i> Lackner <b>gen. nov.,</b> is proposed for the former South African and Namibian members of the genus <i>Pholioxenus</i> Reichardt, with the following new combinations: <i>Paraxenus diasi</i> (Vienna) <b>comb. nov.</b>; <i>Paraxenus eremicola</i> (Thérond) <b>comb. nov.</b>; <i>Paraxenus namibiensis</i> (Vienna) <b>comb. nov.</b>; <i>Paraxenus oleolus</i> (Thérond) <b>comb. nov.</b>; <i>Paraxenus therondi</i> (Olexa) <b>comb. nov.</b>; and <i>Paraxenus uhligi</i> (Mazur) <b>comb. nov.</b> Additionally, based on the analysis of the dispersal patterns, <b>Myrmetini</b> appear to be a bipolar (amphitropical) clade, while <b>Eremosaprinini</b> appear to be exclusive to the Western Hemisphere. <b>Euspilotini</b> are strongly represented in the Western Hemisphere, with only a handful of species known from the Palaearctic/Oriental regions. <b>Saprinini</b> and <b>Hypocaccini</b> are spread worldwide but ar
有74个属和亚属,约740种,是蝉科(鞘翅目:蝉总科)中最大的亚科之一。本文在综合分类取样的基础上,提出了一种皂荚亚科的系统发育假说。这是第一个结合分子和形态学方法(细胞色素c氧化酶亚基1,18S核糖体RNA和93个形态学特征)的系统发育研究。因此,我们提出了一种新的分类;五个新的部落建立起来了:Myrmetini Portevin stat.和sens. nov.;乌斯皮罗蒂尼·拉克纳,部落。11月;Eremosaprinini Lackner,部落。11月;萨普里尼尼·布兰查德,11月;和Hypocaccini Lackner部落。11月,其他命名行为如下:Chelyoxenus Hubbard被降为Geomysaprinus Ross的一个亚属,因此Geomysaprinus (Chelyoxenus) stat. 11月,Nessus Reichardt从Hypocaccus C. Thomson的一个亚属转移到Hypocacculus Bickhardt的一个亚属,因此Hypocacculus (Nessus) stat. rest。以下分类群Paraphilothis Vienna、Styphrus Motschulsky、Xerosaprinus Wenzel、Lophobregmus Wenzel、Vastosaprinus Wenzel、Auchmosaprinus Wenzel、Hemisaprinus Kryzhanovskij & Reichardt、Reichardtia Wenzel和Australopachylopus Lackner & Leschen均降为Saprinus Erichson亚属。因此,Saprinus (Paraphilothis) stat. nov., Saprinus (Styphrus) stat. nov., Saprinus (Xerosaprinus) stat. nov., Saprinus (Vastosaprinus) stat. nov., Saprinus (Auchmosaprinus) stat. nov., Saprinus (Lophobregmus) stat. nov., Saprinus(半球aprinus) stat. rest。新属Paraxenus Lackner gen. nov.由原属Pholioxenus Reichardt的南非和纳米比亚成员组成,并有以下新组合:Paraxenus diasi (Vienna) comb。11月;刺毛蕨(刺毛蕨)梳子。11月;纳米比亚副栉虫(维也纳)梳。11月;毛蕨(毛蕨)梳。11月;凤头凤尾(凤头凤尾)11月;和马祖尔副栉。11 .此外,根据对分布模式的分析,Myrmetini似乎是一个双极性(两性)分支,而Eremosaprinini似乎是西半球独有的。Euspilotini主要分布在西半球,仅在古北/东方地区有少量已知物种。Saprinini和hyppocaccini在世界范围内传播,但在南美洲很少有代表。全北极(特别是新北极)地区被认为是大约8000万年前亚科的起源中心(Ma)。调查被假设为该群体的祖先状态,随后在生活史上发生了几次独立的转变。Saprininae分支发育主要发生在古近纪(66 ~ 23.03 Ma),可能与哺乳动物的多样化有关。

As a result, we propose a new classification; five new tribes are erected: &lt;b&gt;Myrmetini&lt;/b&gt; Portevin &lt;b&gt;stat. and sens. nov.&lt;/b&gt;; &lt;b&gt;Euspilotini&lt;/b&gt; Lackner, &lt;b&gt;trib. nov.&lt;/b&gt;; &lt;b&gt;Eremosaprinini&lt;/b&gt; Lackner, &lt;b&gt;trib. nov.&lt;/b&gt;; &lt;b&gt;Saprinini&lt;/b&gt; Blanchard, &lt;b&gt;sens. nov.&lt;/b&gt;; and &lt;b&gt;Hypocaccini&lt;/b&gt; Lackner, &lt;b&gt;trib. nov&lt;/b&gt;. Additional nomenclatural acts are as follows: &lt;i&gt;Chelyoxenus&lt;/i&gt; Hubbard is downgraded to a subgenus of &lt;i&gt;Geomysaprinus&lt;/i&gt; Ross, thus &lt;i&gt;Geomysaprinus&lt;/i&gt; (&lt;i&gt;Chelyoxenus&lt;/i&gt;) &lt;b&gt;stat. nov.&lt;/b&gt;, &lt;i&gt;Nessus&lt;/i&gt; Reichardt is transferred from a subgenus of &lt;i&gt;Hypocaccus&lt;/i&gt; C. Thomson to a subgenus of &lt;i&gt;Hypocacculus&lt;/i&gt; Bickhardt, thus &lt;i&gt;Hypocacculus&lt;/i&gt; (&lt;i&gt;Nessus&lt;/i&gt;) &lt;b&gt;stat. rest.&lt;/b&gt; The following taxa &lt;i&gt;Paraphilothis&lt;/i&gt; Vienna, &lt;i&gt;Styphrus&lt;/i&gt; Motschulsky, &lt;i&gt;Xerosaprinus&lt;/i&gt; Wenzel, &lt;i&gt;Lophobregmus&lt;/i&gt; Wenzel, &lt;i&gt;Vastosaprinus&lt;/i&gt; Wenzel, &lt;i&gt;Auchmosaprinus&lt;/i&gt; Wenzel, &lt;i&gt;Hemisaprinus&lt;/i&gt; Kryzhanovskij &amp; Reichardt, &lt;i&gt;Reichardtia&lt;/i&gt; Wenzel and &lt;i&gt;Australopachylopus&lt;/i&gt; Lackner &amp; Leschen are all downgraded into subgenera of &lt;i&gt;Saprinus&lt;/i&gt; Erichson. Thus, &lt;i&gt;Saprinus&lt;/i&gt; (&lt;i&gt;Paraphilothis&lt;/i&gt;) &lt;b&gt;stat. nov.&lt;/b&gt;, &lt;i&gt;Saprinus&lt;/i&gt; (&lt;i&gt;Styphrus&lt;/i&gt;) &lt;b&gt;stat. nov.&lt;/b&gt;, &lt;i&gt;Saprinus&lt;/i&gt; (&lt;i&gt;Xerosaprinus&lt;/i&gt;) &lt;b&gt;stat. nov.&lt;/b&gt;, &lt;i&gt;Saprinus&lt;/i&gt; (&lt;i&gt;Vastosaprinus&lt;/i&gt;) &lt;b&gt;stat. nov.&lt;/b&gt;, &lt;i&gt;Saprinus&lt;/i&gt; (&lt;i&gt;Auchmosaprinus&lt;/i&gt;) &lt;b&gt;stat. nov.&lt;/b&gt;, &lt;i&gt;Saprinus&lt;/i&gt; (&lt;i&gt;Lophobregmus&lt;/i&gt;) &lt;b&gt;stat. nov.&lt;/b&gt;, &lt;i&gt;Saprinus&lt;/i&gt; (&lt;i&gt;Hemisaprinus&lt;/i&gt;) &lt;b&gt;stat. rest.&lt;/b&gt;, &lt;i&gt;Saprinus&lt;/i&gt; (&lt;i&gt;Reichardtia&lt;/i&gt;) &lt;b&gt;stat. nov.&lt;/b&gt;, &lt;i&gt;Saprinus&lt;/i&gt; (&lt;i&gt;Australopachylopus&lt;/i&gt;) &lt;b&gt;stat. nov.&lt;/b&gt; A new genus, &lt;i&gt;Paraxenus&lt;/i&gt; Lackner &lt;b&gt;gen. nov.,&lt;/b&gt; is proposed for the former South African and Namibian members of the genus &lt;i&gt;Pholioxenus&lt;/i&gt; Reichardt, with the following new combinations: &lt;i&gt;Paraxenus diasi&lt;/i&gt; (Vienna) &lt;b&gt;comb. nov.&lt;/b&gt;; &lt;i&gt;Paraxenus eremicola&lt;/i&gt; (Thérond) &lt;b&gt;comb. nov.&lt;/b&gt;; &lt;i&gt;Paraxenus namibiensis&lt;/i&gt; (Vienna) &lt;b&gt;comb. nov.&lt;/b&gt;; &lt;i&gt;Paraxenus oleolus&lt;/i&gt; (Thérond) &lt;b&gt;comb. nov.&lt;/b&gt;; &lt;i&gt;Paraxenus therondi&lt;/i&gt; (Olexa) &lt;b&gt;comb. nov.&lt;/b&gt;; and &lt;i&gt;Paraxenus uhligi&lt;/i&gt; (Mazur) &lt;b&gt;comb. nov.&lt;/b&gt; Additionally, based on the analysis of the dispersal patterns, &lt;b&gt;Myrmetini&lt;/b&gt; appear to be a bipolar (amphitropical) clade, while &lt;b&gt;Eremosaprinini&lt;/b&gt; appear to be exclusive to the Western Hemisphere. &lt;b&gt;Euspilotini&lt;/b&gt; are strongly represented in the Western Hemisphere, with only a handful of species known from the Palaearctic/Oriental regions. &lt;b&gt;Saprinini&lt;/b&gt; and &lt;b&gt;Hypocaccini&lt;/b&gt; are spread worldwide but ar","PeriodicalId":22126,"journal":{"name":"Systematic Entomology","volume":"49 1","pages":"48-71"},"PeriodicalIF":4.8,"publicationDate":"2023-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47143396","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
