A new species of the genus Ascogaster Wesmael from China (Hymenoptera: Braconidae: Cheloninae)

A new species of the genus Ascogaster Wesmael (Hymenoptera: Braconidae: Cheloninae), Ascogaster retis Ji et Chen, sp. nov. is described and illustrated from China. The new species is characterized by black body; antenna slightly dilated medially; vertex with coarse transversal areolate rugae; temple almost equal to eye in dorsal view; face coarsely reticulate rugose; clypeus moderate dense punctate, medial apical border pointed forwards into a dull tooth; notauli rather shallow, mesopleuron lacuno punctate without precoxal sulcus; propodeum with four teeth, lateral teeth bigger and middle teeth smaller; carapace with a conical spine at apex, ovipositor sheath short and not beyond carapace in lateral view. The new species is similar to Ascogaster fullawayi (Baker), but differs from the latter in: temple about equal to eye in dorsal view, no sharp angulate teeth between frons and eye orbits; no weak longitudinal carina through the lower part of face; carapace apex with a small and dull conical spine. The type specimens are deposited in the Beneficial Insects Laboratory, College of Plant Protection, Fujian Agriculture and Forestry University, Fuzhou, China.
