A taxonomic study on the genus Ectopioglossa Perkins from Vietnam is presented. Two species, E. henseni Gusenleitner, 1990 and E. taiwana (Sonan, 1938), are recorded as new to the vespid fauna of Vietnam. A key to the Ectopioglossa species known from Vietnam is also provided based on external morphological characters.

To have more knowledge for understanding the diversity of the family Vespidae in the Gia Lai and Dak Lak provinces, we conducted this study to clarify the species composition and distribution of wasps in the Vespidae at different altitudinal zones. The specimen were collected by sweep net.

One social wasp species of subgenus Polistella of the genus Polistes (Hymenoptera: Vespidae: Polistinae), Polistes meadeanus (von Schulthess), is recorded from Tay Nguyen plateau of Vietnam for the first time. This species can be distinguished from all other known species of subgenus Polistella from Vietnam by the metasomal tergum I distinctly longer than its apical width (1.4:1), and petiole of the nest is central, not terminal like almost other Polistella species. Nest structure of the species is also described in detail. Figures of female, male and nest are presented.

Species diversity and abundance of vespid wasps (Vespidae: Hymenoptera) in Cai Kinh, Lang Son province, Vietnam, is examined. A total of 43 species in 22 genera of vespid wasps are recognized in the study area. They are 16 social wasp species belonging to 2 subfamilies, Polistinae (13 species) and Vespinae (3 species), and 27 solitary wasps belonging to the subfamily Eumeninae.

The composition of solitary wasps belonging to subfamily Eumeninae (Vespidae: Hymenoptera) in Huu Lien and Na Hang Nature Reserves has been surveyed. These are two study sites representing two sub-ecological zones, Cao Bang–Lang Son and Tuyen Quang–Ha Giang, which are at altitude below 300 m. As the results, a total of 29 species in 20 genera was recorded in both study sites, of them, 23 species in 16 genera were recorded in Huu Lien, and 23 species in 18 genera were recorded in Na Hang.

Vietnam has a rich social wasp fauna, consisting of three major components: the northern element, of which the center of divergence might be on the eastern slope of Himalaya; the Sundaland species, which are distributed in the southern part of Vietnam; and species widely distributed in the IndoMalayan region.

Variation in the morphology of the adult male reproductive system among different groups of Hymenoptera offer characteristics that help studies of behavior and the evolutionary history of this group. The objective of this study was to describe the adult male reproductive system of the wasp Polistes versicolor versicolor Olivier (Vespidae: Polistini). The reproductive systems were dissected, fixed and embedded for light microscopy. In P. v. versicolor, the reproductive system includes a pair of testes, each one with three fusiform follicles.
