Taxonomic study of the tribe Campsomerini (Hymenoptera, Scoliidae) from northern Vietnam, with the description of a new species and a checklist of Vietnamese scoliid wasps

Abstract

The tribe Campsomerini (Hymenoptera: Scoliidae) from northern Vietnam was studied, resulting in the finding of three species and six subspecies belonging to five genera. Three genera (Megacampsomeris Betrem, 1928 (with M. shillongensis (Betrem, 1928)), Micromerialla Betrem, 1964 (with M. marginella marginella (KIug, 1810)) and Phalerimeris Betrem, 1967 (with P. phalerata phalerata (de Saussure, 1858))) and three species (Sericocampsomeris flavomaculata Gupta & Jonathan, 1989, Campsomeriella (Annulimeris) annulata (Fabricius, 1793) and C. (Campsomeriella) collaris (Fabricius, 1775)) are recorded for the first time from Vietnam. One new species, Sericocampsomeris vietnamica Pham & van Achterberg, sp. nov. is described and illustrated. Identification keys to the genera, species and subspecies of the tribe Campsomerini from northern Vietnam and to the species of Sericocampsomeris Betrem, 1941 are presented. Lastly, we provide a checklist with 13 species and subspecies of Scoliidae from Vietnam.
