Ⅵ. 1963.2. Spilopieron baiyanensis sp. nov.Male : Fore wing 9 mm long.This new species is similar to Spilopteron hongmaoensis Wang, but differs from it by: apex of flagellum of antennae, tibia and tarsus of hind leg, middle lobe and lateral lobes of mesoscutum. first pleural area of propodeum brown or dark brown; mesopleu-rum and inetapleurum with rather shallow and scattered punctures; second lateral area of propodeum not clearly defined; prepectal carina extending to subtegular ridge but interrupted at middle; abdominal tergite 1 about 2.3 as long as apical width, tergite 2 broader than its length.Holotype ((?)), Longsheng (Guangxi), 20.
