Abstract

A new species of Compsoneuriella Ulmer, 1939 is described based on male and female imagos, nymphs and eggs from Ratchaburi province, western Thailand. Compsoneuriella braaschi sp. nov. is closely related to C. thienemanni Ulmer, 1939, from Java and Sumatra, but differs in the larval stage by the maxilla bearing only 8-9 comb-shaped setae on the crown, two strong medial setae on the glossa, gills V-VII apically acutely pointed and the posterior margin of the abdominal terga without distinct rows of submarginal microdenticles. In the male imaginal stage, the new species differs from C. thienemanni by having more reduced spines on the penis lobes and the titillators being directed outwards and strongly pointed at their apices.

摘要

基于采自泰国西部叻丕府的雌雄成虫、若虫和卵，描述了扁角石蛾属（Compsoneuriella）乌尔默（Ulmer）1939年的一个新物种。新物种布拉氏扁角石蛾（Compsoneuriella braaschi sp. nov.）与1939年发现于爪哇和苏门答腊的蒂氏扁角石蛾（C. thienemanni Ulmer）密切相关，但在幼虫阶段有所不同，其上颚顶部仅有8 - 9根梳状刚毛，下咽有两根强壮的中刚毛，鳃V - VII顶端尖锐，腹部背板后缘无明显的亚边缘微齿列。在雄性成虫阶段，新物种与蒂氏扁角石蛾的区别在于阳茎叶上的刺更退化，且刺激器向外指向并在顶端强烈尖锐。
