NOTES ON SPECIES OF VESPID WASPS (VESPIDAE: HYMENOPTERA) IN THE CENTRAL HIGHLAND, VIETNAM

Abstract

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. The species composition and distribution of wasps in the family Vespidae from two altitudinal zones (in Gia Lai and Dak Lak provinces) are provided. The result shows that 74 species of 32 genera of four subfamilies (Sternogastrinae, Polistinae, Vespinae and Eumeninae) were recorded. Of those, 31 species of 18 genera were recorded in both altitudinal zones; 55 species of 30 genera were only recorded at an altitude around 800 m (in Gia Lai); 50 species of 22 genera were only recorded at an altitude lower (300-500 m) (in Dak Lak). In addition, Eustenogaster fraterna is newly recorded for Vietnamese fauna, and its nest description is also provided. The results of this study will serve as a basis for further studies on the biodiversity and conservation of this group.
