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. | TAP CHI SINH 2016, 38(4): 467-472 Diversity of vespid waspsHOC (Vespidae: Hymenoptera) DOI: DIVERSITY OF VESPID WASPS (Hymenoptera: Vespidae) IN LANG SON PROVINCE, VIETNAM Nguyen Thi Phuong Lien Institute of Ecology and Biological Resources, Vietnam Academy of Science and Technology ABSTRACT: 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 nest of Polistes strigosus is described for the first time. The genus Oreumenes of the subfamily Eumeninae is newly recorded for the Vietnamese fauna, represented by Oreumenes decoratus (Smith). When the diversity of vespid wasps in the study area of each year was compared for three years, 2014, 2015 and 2016, the diversity and evenness index were highest in the summer of 2016, suggesting that many vespid species are active in summer. Eumenes quadratus and Delta esuriens were the most abundant species. Keywords: Vespidae, diversity, nest description, new record, vespid wasps, Lang Son, Vietnam.

Corresponding author: phuonglientit@ Received 2 December 2016, accepted 20 December 2016 INTRODUCTION Vespid wasps including social wasps and solitary wasps, namely Stenogastrinae (hover wasps), Polistinae (paper wasps) and Vespinae (hornets and yellow-jackets) and Eumeninae (potter wasps) in the family Vespidae, consist of about 5000 described species worldwide (Picket & Carpenter, 2010). Studies on species composition of vespid wasps have been carried out in Vietnam recently .
