First record of the genus Cisaris Townes (Ichneumonidae: Phygadeuontinae) from Vietnam, with descriptions of four new species

Key Points

Four new species of the genus Cisaris are identified in Vietnam, expanding the known biodiversity.
The descriptions include C. carinatus, C. robustus, C. rugosus, and C. tergalis, with unique features noted.
A modified key to the world species of Cisaris is provided to reflect these new findings.
This record may enhance our understanding of ichneumonid wasps and their distribution in Southeast Asia.

Abstract

The Darwin wasp genus Cisaris is recorded for the first time from Vietnam. Four new species are described on the basis of material from the country including C. carinatus sp. nov., C. robustus sp. nov., C. rugosus sp. nov., and C. tergalis sp. nov. The key to the world species of Cisaris by Sun & Sheng (2011) is modified to include four new species from Vietnam.
