A catalogue of Eumeninae occurring in Oceania is presented, the first in more than a century.

A taxonomic study on the Afrotropical species in the genus Anterhynchium de Saussure, 1863 is presented. Some subspecies are elevated to specific rank (Anterhynchium argenteopilosellum (Giordani Soika, 1937) stat. nov., A. bugandanum Giordani Soika, 1987 stat. nov., A. cariosum Giordani Soika, 1987 stat. nov., A. denticulatum (Mocsáry, 1903) stat. nov., A. sulphureomaculatum (von Schulthess, 1928) stat. nov.).

The nominal subgenus is redefined and divided into the following species-groups: grayi species-group, mephisto species-group, osborni species-group and synagroide species-group. The Malagasy species are transferred from Epiodynerus Giordani Soika to the nominal subgenus but considered as incertae sedis in it. Odynerus natalensis de Saussure, 1855 and Anterhynchium uniforme Gusenleitner, 2012 are transferred to Antodynerus de Saussure, 1855 (Antodynerus natalensis comb. nov. and Antodynerus uniforme comb. nov.), Rhynchium histrionicum Gerstäcker, 1857 is transferred to Euodynerus Dalla Torre, 1904 (Euodynerus (Euodynerus) histrionicus comb. nov.), Rhynchium holomelas André, 1895 is transferred to Pseudagris de Saussure, 1863 (Pseudagris holomelas comb. nov.; = Rhynchium junodianum von Schulthess, 1899 syn. nov.; = Synagris aterrima Maidl, 1914 syn. nov.), Anterhynchium obscurum Gusenleitner, 2007 is transferred to Tricarinodynerus Giordani Soika, 1952 (Tricarinodynerus obscurus comb. nov.). Anterhynchium dahomeyicus Gusenleitner, 2018 is a junior synonym of Aethiopicodynerus punctiventris (Gusenleitner, 2002) syn. nov. Lectotypes for Odynerus andreanus de Saussure, 1890 and Rhynchium sulphureomaculatum von Schulthess, 1928 are designated. A key to the species is provided.

Other new synonymies are Anterhynchium tamarinum septentrionale Giordani Soika = Anterhynchium tamarinum tamarinum (de Saussure), Ischnocoelia robusta analis Giordani Soika = I. robusta robusta (Meade-Waldo), Pseudabispa bicolor flavescentula (Giordani Soika) = P bicolor bicolor (de Saussure), Pseudalastor tridentatus septentrionalis Giordani Soika = P. tridentatus tridentatus Giordani Soika and Rhynchium australense Perkins = R. magnificum Smith.

An updated checklist of the Arabian species of Vespidae is provided here. The list includes 163 identified species in 49 genera and four subfamilies: Eumeninae (41 genera, 130 species), Masarinae (4 genera, 14 species), Polistinae (3 genera, 17 species) and Vespinae (1 genus, 2 species). Distributions, both on the Peninsula and extra-limital, are provided for each species and subspecies; 53 species (33%) are endemic to the Arabian Peninsula, as are 15 subspecies. A new combination is proposed: Knemodynerus sauditus (Giordani Soika, 1989) comb. nov., transferred from Trachyodynerus Giordani Soika, 1989.

A taxonomic revision of the Protopolybia picteti-emortualis species-group now demonstrates that this group is possibly the largest in Protopolybia, comprising 15 species: P. eldinaris sp. nov.; P. djaneteae sp. nov.; P. cameranii (Zavattari 1906) = P. bella (Von Ihering 1903) syn. nov.; P. fulvotincta stat. rev.; P. biguttata, P. nitida, P. alvarengai, P. iheringi, P. perfulvula, P. steinbachi, P. wheeleri, P. rotundata, P. picteti, P. emortualis and P. duckei. Male and female genitalia are illustrated for P. biguttata Bequaert, P. bella, P. nitida, P. fulvotincta and P. picteti. New collection records and a new identification key are presented for this species-group.

In this study, the mitochondrial genomes of three Stenogastrinae species, Eustenogaster scitula, Liostenogaster nitidipennis and Parishnogaster mellyi were sequenced and annotated, and a total of 16 vespid mtgenomes are comparatively analyzed. Our results indicate that codon usage bias is mainly dominated by mutational pressure, and affected only slightly by natural selection. Selective pressure analysis of protein-coding genes (PCGs) shows that the highest evolutionary rate is present in NADH complex I, and the lowest in cox1. Compared with the reported mtgenomes of other Vespidae, in Stenogastrinae, trnH is shifted to a new position. Phylogenetic analyses are performed using Bayesian method and Maximum Parsimony. Phylogenetic analysis further confirms that the Stenogastrinae is the sister group of all remaining Vespidae. Divergence time of Stenogastrinae from other Vespidae is estimated at ~ 166 Mya. Our results also support that eusociality evolved twice in the family Vespidae., (Copyright © 2019 Elsevier B.V. All rights reserved.)

Eight new species, namely Parancistrocerus latitergus sp. nov. (China), P. lamnulus sp. nov. (China), P. laticlypeus sp. nov. (Thailand), P. prominens sp. nov. (Thailand), P. guangxiensis sp. nov. (China), P. discarinatus sp. nov. (Thailand), P. abyssicavus sp. nov. (Thailand), and P. similiandrocles sp. nov. (China) are described and illustrated. Parancistrocerus samarensis (von Schulthess, 1934) and P. incorruptus incorruptus Giordani Soika, 1972, are newly recorded from China and Thailand, respectively. An updated key to the Oriental species of the genus Parancistrocerus is also given.

The genus Orientalicesa has six species, and all of them have been recorded in the Oriental region (including Indonesia, Malaysia, Phillippines, Laos, China). In this paper, the genus Orientalicesa is newly recorded from Vietnam, represented by one species O. confasciatus Tan and Carpenter. This species was mistakenly redescribed as Stenodyneriellus rangpocus Kumar, Carpenter Kishore, 2017. A new synonym of O. confasciatus is proposed, and that species is a new record for India.

A new species of Eumeninae, Stenodynerus punjabensis Qasim, Carpenter et Rafi, is described from Pakistan. A key to the Stenodynerus species of Pakistan is also included.

The Hymenoptera--ants, bees and wasps--represent one of the most successful but least understood insect radiations. We present the first comprehensive molecular study spanning the entire order Hymenoptera. It is based on approximately 7 kb of DNA sequence from 4 gene regions (18S, 28S, COI and EF-1α) for 116 species representing all superfamilies and 23 outgroup taxa from eight orders of Holometabola. Results are drawn from both parsimony and statistical (Bayesian and likelihood) analyses, and from both by-eye and secondary-structure alignments. Our analyses provide the first firm molecular evidence for monophyly of the Vespina (Orussoidea+Apocrita). Within Vespina, our results indicate a sister-group relationship between Ichneumonoidea and Proctotrupomorpha, while the stinging wasps (Aculeata) are monophyletic and nested inside Evaniomorpha. In Proctotrupomorpha, our results provide evidence for a novel core clade of proctotrupoids, and support for the recently proposed Diaprioidea. An unexpected result is the support for monophyly of a clade of wood-boring sawflies (Xiphydrioidea+Siricoidea). As in previous molecular studies, Orussidae remain difficult to place and are either sister group to a monophyletic Apocrita, or the sister group of Stephanidae within Apocrita. Both results support a single origin of parasitism, but the latter would propose a controversial reversal in the evolution of the wasp-waist. Generally our results support earlier hypotheses, primarily based on morphology, for a basal grade of phytophagous families giving rise to a single clade of parasitic Hymenoptera, the Vespina, from which predatory, pollen-feeding, gall-forming and eusocial forms evolved., (Copyright © 2011 Elsevier Inc.
