Taxonomic study of wasp species in the Polybia (Myrapetra) occidentalis group morphologically related to P. scrobalis and P. flavifrons, with description of a new species (Hymenoptera, Vespidae, Polistinae).

The genus is dominant in the Neotropics, with more than 59 described species and eleven recognized subgenera. Myrapetra is the largest subgenus, currently with twenty-four valid species and fourteen subspecies, most of them allocated in the "P.

Taxonomic account and phylogenetic relationships of the species of the Neotropical social wasp genus Chartergus Lepeletier, 1836 (Vespidae: Polistinae: Epiponini).

To investigate the phylogenetic relationships within the genus, we used a combined dataset of morphological characters, nest architecture traits, and molecular data. The results revealed the following relationships among the Chartergus species: (C.

Taxonomic notes on the genus Charterginus Fox, 1898 (Vespidae: Polistinae: Epiponini) with images of the type specimens and new occurrence records.

Charterginus Fox, 1898 is a neotropical genus of swarm-founding social wasps consisting of six species. Despite its ecological significance, there are limited studies on various aspects of these wasps. To address this, this study aims to provide a comprehensive comparative diagnosis for all Charterginus species, accompanied by high-quality images of the type material.

Divergence time analysis of the Neotropical wasp genus Protopolybia Ducke, 1905 (Vespidae, Polistinae, Epiponini) using a Multilocus Phylogenetic Approach.

The genus Protopolybia Ducke was analyzed using a multilocus phylogenetic approach, which confirmed its monophyly. In contrast with the arrangements derived solely from morphological data, however, this analysis divides the genus into only two major clades. The study also presents divergence times for the origin and diversification of Protopolybia, which are related to possible vicariant events occurring in the Amazon biome.

Cladistic analysis and reclassification of Synagris Latreille (Hymenoptera: Vespidae: Eumeninae).

A cladistic analysis of the genus Synagris is performed to assess the taxonomic status and limits of its subgenera, examining external morphology and male genitalia. The subgenera S. (Rhynchagris) and S.

First Comprehensive Analysis of Both Mitochondrial Characteristics and Mitogenome-Based Phylogenetics in the Subfamily Eumeninae (Hymenoptera: Vespidae).

The subfamily Eumeninae plays a significant role in the biological control of agricultural pests. However, the characteristics of eumenine mitogenomes that are important molecular markers for phylogenetics are not clearly revealed. Here, 52 eumenine mitogenomes are newly sequenced and annotated, and the phylogenetic relationships of the subfamily are comprehensively analyzed based on 87 vespid mitogenomes.

Marimbondos: systematics, biogeography, and evolution of social behaviour of neotropical swarm-founding wasps (Hymenoptera: Vespidae: Epiponini).

Neotropical swarm-founding wasps are divided into 19 genera in the tribe Epiponini (Vespidae, Polistinae). They display extensive variation in several colony-level traits that make them an attractive model system for reconstructing the evolution of social phenotypes, including caste dimorphism and nest architecture. Epiponini has been upheld as a solid monophyletic group in most phylogenetic analyses carried out so far, supported by molecular, morphological and behavioural data.

Catalogue of the Australian Eumeninae (Hymenoptera: Vespidae).

A catalogue of Eumeninae occurring in Australia is presented. The genus Lissodynerus Giordani Soika is synonymized with Pararrhynchium de Saussure. Species placed in the genus Pseudepipona de Saussure, by Giordani Soika and Borsato are transferred to Euodynerus Dalla Torre, and species placed in the genus Syneuodynerus Blüthgen, by Giordani Soika are transferred to Stenodyneriellus Giordani Soika.

The first divergence time estimation of the subfamily Stenogastrinae (Hymenoptera: Vespidae) based on mitochondrial phylogenomics.

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.
