Abstract

A new species of black fly, Simulium (Gomphostilbia) isanense, is described based on females, males, pupae and mature larvae from Thailand. This new species is placed in the Simulium epistum species-group of the subgenus Gomphostilbia Enderlein. It is characterized by the pupal gill with eight filaments arranged as 3+3+2 from dorsal to ventral, of which an inner filament of the ventral pair is slightly longer than its counter filament. Taxonomic notes are provided to distinguish this new species from S. (G.) angulistylum Takaoka & Davies from Peninsular Malaysia, and three other related species. The difference between this new species and S. (G.) angulistylum is supported by genetic distances using the mitochondrial COI gene.

摘要

基于采自泰国的雌虫、雄虫、蛹和成熟幼虫，描述了一种新的蚋类，即伊桑蚋（Simulium (Gomphostilbia) isanense）。这个新物种被归入贡氏蚋亚属（Gomphostilbia Enderlein）的epistum蚋物种组。其特征是蛹鳃有8根鳃丝，从背到腹排列为3+3+2，其中腹侧一对鳃丝的内侧鳃丝略长于其对应的外侧鳃丝。提供了分类学注释，以将这个新物种与来自马来西亚半岛的角柱蚋（S. (G.) angulistylum Takaoka & Davies）以及其他三个相关物种区分开来。利用线粒体COI基因的遗传距离，证实了这个新物种与角柱蚋之间的差异。
