Wings hyaline; pterostigma brown. ♀ unknown. T a x o n o m i c a l r e m a r k. This new species can easily be identified by the unique flagellar structure and color pattern. In the key of non-Nearctic Euceros species (BARRON 1978) the species runs to Euceros pectinis BARRON, but differs by its flagellum and different color patterns on mesosoma, metasoma and legs. Despite a different color pattern, this specimen might represent the unknown male of Eucerus albibasalis UCHIDA due to a similar form of the pronotal process, but more material and / or genetical data are necessary to confirm a possible correlation of both sexes. D i s t r i b u t i o n: Only known from Northern China.	en	Riedel, Matthias (2025): Notes on some Asian species of Euceros GRAVENHORST, with description of a new species (Hymenoptera, Ichneumonidae, Eucerotinae).
