Two new species of Episymploce Bey-Bienko, 1950 (Blattodea, ectobiidae, blattellinae) from China

Abstract

Two new species of Episymploce Bey-Bienko from China are described. Nine individuals of E. sichuanensis sp. nov. were collected from Sichuan Province and four individuals of E. maxima, sp. nov. were collected from Guangxi Province. Morphology, especially the wings, specialized abdominal tergum and genitalia of adults, are described and illustrated in detail. Episymploce sichuanensis sp. nov. is similar to E. kunmingi (Bey-Bienko, 1969), but can be easily distinguished by the reduced wings, bifurcated two processes at the hind margin of the supra-anal plate, and the unspecialized first abdominal tergum (T1). Episymploce maxima sp. nov. is similar to E. taiheizana Asahina, 1979 but is distinguished by its large size, the latero-medial margins of the subgenital plate without processes, and the unspecialized T1. A key to the recorded Episymploce species from China is provided in this paper.
