Three new species of the tribe Synergini (Hymenoptera, Cynipidae), i.e., Lithosaphonecrus arcoverticus Liu, Zhu et Pang, sp. n. Lithosaphonecrus decarinatus Liu, Zhu et Pang, sp. n. and Saphonecrus emarginatus Liu, Zhu et Pang, sp. n. are described from Hunan, China. The three species have emerged from the same galls collected on Lithocarpus glaber (Thunb.) in December, June, and April, respectively. Phylogenetic reconstruction of Synergini based on mtDNA COI and rRNA 28S D2 genes resolved two independent monophyletic clades exclusively associated with Lithocarpus plant hosts, i.e., the genus Lithosaphonecus and the lithocarpii species complex of Saphonecrus. The three species each have a sister relationship with a congener in Taiwan, an island off the southeastern coast of continental China. This recurrent disjunct distribution and relatively low COI sequence variation between the sister species in each species pair are considered attributable to the formation of the Taiwan Strait in Holocene ca 10,000 years ago. We also discussed the possible speciation mechanism for Lithosaphonecrus due to seasonality and topography in subtropical China. Finally, we addressed the need for conservation consideration in urbanization planning.
Synergini族的三个新种（膜翅目，Cynipidae），即Liu，Zhu et Pang，sp。n.Lithosaphonecrus decarinatus Liu，Zhu et Pang，sp.n和Saphonecrus emarginatus Liu、Zhu et Peng，sp。n.来自中国湖南。这三个物种分别于12月、6月和4月从光石竹上采集的同一种胆囊中出现。基于mtDNA COI和rRNA 28S D2基因的Synergini系统发育重建解决了两个独立的单系分支，即Lithosaphonecus属和Saphonecrus的lithocarpii物种复合体。这三个物种都与台湾的一个同类有姐妹关系，台湾是中国大陆东南沿海的一个岛屿。这种反复出现的间断分布和每个物种对中姐妹物种之间相对较低的COI序列变化被认为是约10000年前全新世台湾海峡形成的原因。我们还讨论了中国亚热带地区由于季节性和地形因素而可能形成的石竹的形成机制。最后，我们讨论了在城市化规划中考虑保护的必要性。

The Eoneria-group was proposed to gather species with opaque antennal base from all biogeographical regions. Recently, the Eoneria-group was redefined to comprise only three genera from the Neotropical Region: Antillonerius, Eoloxozus and Eoneria. Herein, we redescribe the species of the Eoneria-group and perform a phylogenetic analysis based on 49 morphological characters. Our results corroborate the monophyly of the Eoneria-group (excluding Antillonerius bistriatus (Williston)), supported by nine synapomorphies. Antillonerius solitarius (Johnson) stat. rev. is revalidated from synonymy with Antillonerius cinereus (Röder) and a key for the species in the Caribbean islands is provided. New combinations are proposed for Eoloxozus sabroskyi Aczél, which is transferred to Eoneria, and Nerius bistriatus Williston, which is transferred to Glyphidops. Additionally, new records of E. aczeli Sepúlveda & de Carvalho are provided for Venezuela and of E. blanchardi, for Venezuela and Paraguay.

The taxonomic history, composition, morphology, distribution, and bionomics of the genus Dila Fischer von Waldheim, 1844 are discussed. The following new generic synonymy is established: Dila Fischer von Waldheim, 1844 = Caenoblaps König, 1906, syn.n. As a result, four species are transferred from Caenoblaps to the genus Dila: Dila difformis (König, 1906), comb.n., Dila nitida (Schuster, 1920), comb.n., Dila baeckmanni (Schuster, 1928), comb.n., Dila kulzeri (Schuster, 1928), comb.n. A new synonymy is established: Blaps kulzeri Pierre, 1964 = Caenoblaps kulzeriana Pierre, 1964, syn.n. A taxonomic review of the eight known Caucasian, Turkish and Iranian species is given. Lectotypes of Caenoblaps nitida and Caenoblaps difformis are designated. Three new species are described: Dila hakkarica sp.n. and Dila svetlanae sp.n. from the Hakkary Province of Turkey and Dila crenatopunctata sp.n. from West Azerbaijan Province of Iran. The position of the genus Dila within the tribe Blaptini and subtribal classification are discussed.

Among the 32 tribes of Coreinae currently recognized, Spartocerini comprises 66 extant species distributed in six genera: Euagona Dallas, Eubule Stål, Menenotus Laporte, Molchina Amyot & Serville, Sephina Amyot & Serville and Spartocera Laporte, distributed exclusively in the Western Hemisphere. We performed cladistic analyses using equal (EW) and also implied weighting (IW) based on 56 terminals (23 belonging to the ingroup) and 115 morphological characters, including male and female genitalia. Spartocerini was polyphyletic both under EW and IW because Molchina was nested in Mictini. We remove Molchina from Spartocerini and consider the genus as incertae sedis. Spartocera, Eubule, and Sephina were not recovered as monophyletic. Sephina pubera (Erichson) is considered as incertae sedis within Spartocerini, Eubule ampliata (Valdés) is transferred to Spartocera as a new combination, and Mamurius is included in Anisoscelini.

The recent critical revision of the order Skleroptera by Beutel et al. (2018a) is considered. We show several defects in their interpretation, contradicted by the original descriptions and diagnosis (Nel et al., 2013; Kirejtshuk & Nel, 2013). The main arguments of the initial interpretation of Stephanastus polinae Kirejtshuk et Nel, 2013 (Stephanastidae) and reasons for the proposal of the order Skleroptera (Kirejtshuk & Nel, 2013) are mentioned, together with reasons to reject the proposal of Beutel et al. (2018a, b). A comparison of Skleroptera with other neopteran orders is made. Lastly the problem of the position of Umenocoleus as a member of Coleopterida versus a roachoid is discussed, the first hypothesis being supported by synapomorphies which is not the case for the second.
考虑了Beutel等人（2018a）最近对Skleroptera目的关键修订。我们在他们的解释中发现了几个缺陷，与最初的描述和诊断相矛盾（Nel等人，2013；Kirejtshuk和Nel，2013）。提到了对Stephanastus polinaeKirejtshuk et Nel，2013（Stephanastidae）的初步解释的主要论点和提出Skleroptera目的原因（Kirejtschuk&Nel，2013.），以及拒绝Beutel等人的建议的理由。（2018a，b）。将斯克勒翅目与其他新翅目进行了比较。最后，讨论了Umenocoleus作为鞘翅目成员与蟑螂类成员的地位问题，第一种假说得到了突触形态的支持，而第二种假说则不然。

This paper provides a synopsis of the South American genus Diabroctis Gistel, 1858. Five species are assigned to the genus. The type species D. mimas is widely distributed and shows considerable morphological variation in male secondary sexual characters. A substantial number of morphological and geographic data are used to provide an updated diagnosis of this species, and to describe intraspecific variation. A new Brazilian species is described as Diabroctis pseudomimas sp. nov., which has been recognized among specimens confused with D. mimas (Linnaeus) in entomological collections. Additionally, the subspecies D. mimas venezuelensis is elevated to species level. Lectotypes are designated for Phanaeus mirabilis and Phanaeus mimaeformis. Diagnoses, distribution data, and an identification key are provided for all species included in the genus.

Ageniella is the second-most diverse spider wasp genus in Ageniellini (Pepsinae). The Ageniella (Ageniella) accepta species-group is found from Canada to Panama and is composed of three Nearctic species: A. accepta (Cresson), A. blaisdelli (Fox), and A. conflicta Banks. Within this group, species-level identification is difficult, because diagnostic characters are questionable, and subjective for both males and females. Furthermore, sexes of each species are not reliably associated. Herein, we investigate sex associations and the validity of described species within the A. accepta species-group based on three molecular markers (cytochrome oxidase I, wingless, long-wavelength rhodopsin) by using maximum likelihood and Bayesian phylogenetic analyses, and species-delimitation approaches. Additionally, we mapped 12 morphological traits onto the molecular phylogeny to discuss evolution of diagnostic characters. We concluded that the three species of the A. accepta species-group are actually a single, wide-ranging species with strong geographical signal. Moreover, our results suggest introgression at the mitochondrial level.
小蜂属(Ageniella)是小蜂科(Ageniellini)中种类第二丰富的蛛蜂属。Ageniella (Ageniella) accepta种群分布于加拿大至巴拿马，由三个新北极物种组成:A. accepta (Cresson)， A. blaisdelli (Fox)和A. conflicta Banks。在这个群体中，物种水平的鉴定是困难的，因为诊断特征是可疑的，而且对雄性和雌性都是主观的。此外，每个物种的性别并不可靠地联系在一起。本文基于细胞色素氧化酶I、无翅、长波紫红质三种分子标记，采用最大似然分析、贝叶斯系统发育分析和物种划分方法，研究了拟南花属物种群中所描述物种的性别关联和有效性。此外，我们将12个形态特征映射到分子系统发育上，以讨论诊断特征的进化。结果表明，这3个种实际上是一个广泛分布的单一种，具有较强的地理信号。此外，我们的结果表明在线粒体水平上存在渗入。
