Conflicting hypotheses about the relationships among the major lineages of aculeate Hymenoptera clearly show the necessity of detailed comparative morphological studies. Using micro-computed tomography and 3D reconstructions, the skeletal musculature of the mesoand metathorax and the first and second abdominal segment in Apoidea are described. Females of Sceliphron destillatorium, Sphex (Fernaldina) lucae (both Sphecidae), and Ampulex compressa (Ampulicidae) were examined. The morphological terminology provided by the Hymenoptera Anatomy Ontology is used. Up to 42 muscles were found. The three species differ in certain numerical and structural aspects. Ampulicidae differs significantly from Sphecidae in the metathorax and the anterior abdomen. The metapleural apodeme and paracoxal ridge are weakly developed in Ampulicidae, which affect some muscular structures. Furthermore, the muscles that insert on the coxae and trochanters are broader and longer in Ampulicidae. A conspicuous characteristic of Sphecidae is the absence of the metaphragma. Overall, we identified four hitherto unrecognized muscles. Our work suggests additional investigations on structures discussed in this paper.

Himalcercyon Hebauer, 2002 stat. nov. is elevated to genus rank based on the unique form of its mesoventral elevation. The genus is reviewed, redescribed, and illustrated in detail. Two species are recognized: Himalcercyon mirus (Hebauer, 2002) comb. nov. from Nepal and H. franzi sp. nov. from Chinese Himalaya (Xizang Autonomous Region). Both species are illustrated and diagnosed. An updated key to the Asian genera of the tribe Megasternini (Coleoptera, Hydrophilidae, Sphaeridiinae) is provided, along with the SEM micrographs of ventral morphology of these genera. New replacement name Oreosternum nom. nov. is proposed for Oreocyon Hebauer, 2002 which is preoccupied by Oreocyon Marsh, 1872 (Mammalia, Oxyenidae) and Oreocyon Krumbiegel, 1949 (Mammalia, Canidae).

The ground beetle genusAgonumBonelli, 1810 is a large genus of the tribe Platynini with many species that show high amounts of intraspecific variations, making a correct identification challenging. As part of the German Barcode of Life initiative, this publication provides a comprehensive DNA barcode library for species ofAgonumthat are reported for Germany. In total, DNA barcodes from 258 beetles and 23 species were analysed using the Barcode of Life Data System (BOLD) workbench, including sequences from former studies and 68 newly-generated sequences. The neighbour-joining analyses, based on K2P distances, revealed distinct clustering for all studied species, with unique Barcode Index Numbers (BINs) for 15 species (65%). BIN sharing but distinct clustering was found for three species pairs:Agonum micans/Agonum scitulum,Agonum impressum/Agonum sexpunctatumandAgonum duftschmidi/Agonum emarginatum. The given dataset and its analysis represent another important step in generating a comprehensive DNA barcode library for the ground beetles of Germany and Central Europe in terms of modern biodiversity research.

Using high-resolution stereomicroscopy and exploratory data analyses, a taxonomic revision of the cryptic species close to Plagiolepis schmitzii Forel, 1895, called Pl. schmitzii group, was conducted. Morphology was numerically recorded under highly standardised conditions considering absolute size and 16 shape, pubescence and surface characters. A key to the non-parasitic Westpalaearctic species of the ant genus Plagiolepis Mayr, 1861 is provided which firstly separates, on species group level, the Pl. pygmaea (Latreille) species group, the Pl. pallescens Forel species group and the Pl. schmitzii species group and, finally, on species level, the cryptic species of the latter group. The recognised species of the Pl. schmitzii species group are Pl. schmitzii Forel, 1895 (invasive species), Pl. barbara Santschi, 1911, Pl. atlantis Santschi, 1920 and Pl. invadens sp. nov. (invasive species) that is described as new from a supercolony in Germany. Based on morphological arguments, the taxa Pl. barbara var. madeirensis Emery, 1921, Pl. maura polygyna Santschi, 1922 and Pl. schmitzii var. tingitana Santschi, 1936 are recognised as junior synonyms of Pl. schmitzii, the taxa Pl. schmitzii crosi Santschi, 1920, Pl. pallescens var. kabyla Santschi, 1920 and Pl. perperamus Salata et al., 2018 as junior synonyms of Pl. atlantis and the taxon Pl. maura Santschi, 1920 as junior synonym of Pl. barbara. A concluding comparative section suggests that pre-adaptations for anthropogenous dispersal and transformation to supercoloniality in introduction areas are apparently common traits in Plagiolepis ants.
利用高分辨率立体显微镜技术和探索性数据分析，对与schmitzii Forel, 1895相近的隐种Pl. schmitzii类群进行了分类修正。形态学在高度标准化的条件下进行了数值记录，考虑了绝对大小和16的形状、短柔毛和表面特征。本文提供了westpalanorth蚂蚁属(Plagiolepis Mayr, 1861)非寄生种的一个关键，首先在种群水平上分离出Pl. pygmaea (Latreille)种群、Pl. pallescens Forel种群和Pl. schmitzii种群，最后在种群水平上分离出后者的隐种。已知的Pl. schmitzii种群有Pl. schmitzii Forel, 1895年(入侵种)，Pl. barbara Santschi, 1911年，Pl. atlantis Santschi, 1920年和Pl. invadens sp. nov(入侵种)，被描述为来自德国一个超级群落的新物种。基于形态学上的争论，分类群Pl. barbara var. madeirensis Emery(1921)、Pl. maura polygyna Santschi(1922)和Pl. schmitzii var. tingitana Santschi(1936)被认为是Pl. schmitzii的初级同义词;分类群Pl. schmitzii crosi Santschi(1920)、Pl. pallescens var. kabyla Santschi(1920)和Pl. perperamus Salata等人(2018)被认为是Pl. atlantis的初级同义词;分类群Pl. maura Santschi(1920)被认为是Pl. barbara的初级同义词。最后的比较部分表明，斜蚁在引进地的人为扩散和向超殖民地的转变的预适应显然是其共同的特征。

Male and female of Nusalala peruanasp. nov., a flightless hemerobiid from the Andes mountain range of northern Peru, at a height of almost 4000 m, are described, figured and documented as the first record of a brachypterous, flightless species of Nusalala Navás, 1913, from this country. The other two congeneric, brachypterous species are from high altitudes in Colombia and Costa Rica and have been described in the male sex only – the females remain unknown. The coriaceous domed forewings are shared by all three brachypterous Nusalala species. The ribbon-like hindwings of the male of N. peruanasp. nov. are unique, since those of the other brachypterous males are scale-like, as are the hindwings of the female of N. peruanasp. nov. Distribution and evolutionary backgrounds of brachyptery and flightlessness in Neuropterida are discussed.

Two tenthredinid sawfly species are newly recorded in Germany: Pristiphora krausi (Lacourt, 2006) and P. melagonia sp. nov. The latter is also recorded from Greece and Spain. These species belong to the Pristiphora depressa group, as confirmed by genetic data. Additional data are presented for seven other tenthredinid species which have only rarely been recorded in Germany and for which previously-published data are incomplete. Identification keys to the West Palaearctic species of Eurhadinoceraea and the Pristiphora depressa group are included. Other species of Symphyta, first recorded in Germany since the publication of the most recent checklist, are listed in a table, with references to literature which describes identification characters.

Tomares hairstreaks comprise about 10 species distributed from Europe and North Africa to Central Asia. The taxonomy of the genus is hampered by the absence of diagnostic characters by which specimens can be unambiguously assigned to species. Our investigation of morphology and DNA barcode variations within and between Tomares species shows that while well-defined species (T. ballus, T. mauritanicus, T. callimachus, T. desinens and T. fedtschenkoi) diverge, poorly characterized taxa (T. nogelii, T. nesimachus, T. dobrogensis, T. romanovi and T. telemachus) show very little to no differentiation in mtDNA. We reinstate Tomares callimachus spp. hafis (Kollar, 1849) as a valid subspecies (stat. rev.) and propose taxa telemachus Zhdanko, 2000 and uighurica Koçak, Seven & Kemal, 2000 as synonyms of T. romanovi and T. nogelii nogelii respectively (syn. nov.). We relegate Polyommatus epiphania Boisduval, 1848, recently revived as a valid subspecies of T. callimachus, back to synonymy under the latter, and reconsider the status of T. nogelii dobrogensis (Caradja, 1895) in the light of new molecular data. We use a nuclear gene (EF-1α) in addition to COI barcodes to reconstruct the phylogeny of the group.
番茄的毛纹包括大约10种，分布在欧洲和北非到中亚。该属的分类学由于缺乏诊断特征而受到阻碍，通过这些特征，标本可以明确地分配给物种。我们对Tomares物种内部和物种之间的形态和DNA条形码差异的研究表明，虽然定义明确的物种(T. ballus, T. mauritanicus, T. callimachus, T. desinens和T. fedtschenkoi)存在分歧，但特征不明确的分类群(T. nogelii, T. nesimachus, T. dobrogensis, T. romanovi和T. telemachus)在mtDNA上几乎没有分化。我们恢复了Tomares callimachus spp. hafis (Kollar, 1849)作为一个有效的亚种(stat. rev.)，并提出telemachus Zhdanko, 2000和uighurica koak, Seven & Kemal, 2000分别作为T. romanovi和T. nogelii nogelii的同义词(syn11 .)。我们将最近作为T. callimachus的一个有效亚种复活的Polyommatus epiphania Boisduval(1848)降级为后者的同义词，并根据新的分子数据重新考虑T. nogelii dobrogensis (Caradja, 1895)的地位。我们使用核基因(EF-1α)和COI条形码来重建该群体的系统发育。

Bayesian and parsimony phylogenetic analyses of combined and partitioned datasets of molecular (partial sequences of 28S, wg, COI, and CAD) and morphological (51 characters of adults) data for exemplar taxa of five outgroup and 76 ingroup abacetine carabids resulted in a monophyletic Loxandrina Erwin & Sims, 1984 that is split into Australian and American clades. The genus Loxandrus LeConte, 1853 as previously delimited is not monophyletic relative to numerous genus-level taxa in Abacetini Chaudoir, 1873 and is restricted to a subgenus of North American species. A reclassification and nomenclatural changes for the subtribe that are consistent with the phylogeny are provided. Three genera are removed from Loxandrina: Aulacopodus Britton, 1940 moved to Pterostichini Bonelli, 1810; Cosmodiscus Sloane, 1907 and Tiferonia Darlington, 1962 moved to Abacetina. Based on the phylogenetic relationships and nomenclatural priority only four genera are recognized in Loxandrina: Cerabilia Laporte, 1867, Zeodera Laporte, 1867, Pediomorphus Chaudoir, 1878, and Oxycrepis Reiche, 1843. All other previously recognized genera are treated as subgenera. The classification change created eight secondary homonyms that are resolved by the proposal of the following: Oxycrepis gebi, replacement name for O. balli (Straneo, 1993); O. amatona, replacement name for O. matoana (Straneo, 1993); O. xiproma, replacement name for O. proxima (Straneo, 1993); O. rasutulis, replacement name for O. suturalis (Straneo, 1993); O. laevinota, replacement name for O. laevicollis (Bates, 1871); O. arvulap, replacement name for O. parvula (Straneo, 1951); O. noaffine, replacement name for O. affinis (Straneo, 1991); O. alutona, replacement name for O. notula (Tschitschérine, 1901). An overview of the morphological characteristics and diagnostic features of Loxandrina taxa is provided. A key and habitus images are provided for identification of genera and subgenera. The possible historical biogeography of the group is discussed in light of their phylogenetic relationships and past geological events.

Based on the phylogenetic relationships and nomenclatural priority only four genera are recognized in Loxandrina: Cerabilia Laporte, 1867, Zeodera Laporte, 1867, Pediomorphus Chaudoir, 1878, and Oxycrepis Reiche, 1843. All other previously recognized genera are treated as subgenera. The classification change created eight secondary homonyms that are resolved by the proposal of the following: Oxycrepis gebi, replacement name for O. balli (Straneo, 1993); O. amatona, replacement name for O. matoana (Straneo, 1993); O. xiproma, replacement name for O. proxima (Straneo, 1993); O. rasutulis, replacement name for O. suturalis (Straneo, 1993); O. laevinota, replacement name for O. laevicollis (Bates, 1871); O. arvulap, replacement name for O. parvula (Straneo, 1951); O. noaffine, replacement name for O. affinis (Straneo, 1991); O. alutona, replacement name for O. notula (Tschitschérine, 1901). An overview of the morphological characteristics and diagnostic features of Loxandrina taxa is provided. A key and habitus images are provided for identification of genera and subgenera. The possible historical biogeography of the group is discussed in light of their phylogenetic relationships and past geological events.","PeriodicalId":50592,"journal":{"name":"Deutsche Entomologische Zeitschrift","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2020-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48157888","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
The leafhopper genus Opsius Fieber, 1866 is revised for the Kingdom of Saudi Arabia. Seven species are treated, including three that previously were reported by Dlabola (1979), O. pallasi (Lethierry, 1874), O. tigripes (Lethierry, 1876), and O. versicolor (Distant, 1908). Opsius heydeni (Lethierry, 1876), O. richteri Dlabola 1960, and O. scutellaris (Lethierry, 1874) are reported for the first time from the Kingdom. A new species, O. wilsoni El-Sonbati, sp. nov. is described from the southwestern region of the Kingdom of Saudi Arabia. A key to the species of Opsius of the Kingdom is also provided.
