Simulium (Gomphostilbia) laosense sp. nov. is described based on adults, pupae, and mature larvae from Laos. This new species is placed in the Simulium batoense 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, and is 1.7-1.8 times as long as filaments of the middle triplet. Taxonomic notes are provided to distinguish this new species from Simulium (G.) johorense Takaoka, Sofian-Azirun & Ya'cob from Peninsular Malaysia and four other related species. The phylogenetic position of this new species in the S. batoense species-group is also presented based on the mitochondrial COI gene. This new species represents the second species known from Laos.
老挝蚋新种(Simulium (Gomphostilbia) laosense sp. nov.)依据采自老挝的成虫、蛹和成熟幼虫进行描述。该新种归入Enderlein亚属Gomphostilbia的batoense蚋物种组。其特征为蛹鳃具8根鳃丝,从背至腹排列为3 + 3 + 2,其中腹侧一对鳃丝中的内侧鳃丝略长于其相对的鳃丝,且长度为中间三联体鳃丝的1.7 - 1.8倍。提供了分类学说明,以将该新种与来自马来西亚半岛的柔佛蚋(Simulium (G.) johorense Takaoka, Sofian-Azirun & Ya'cob)及其他4个近缘物种区分开来。基于线粒体COI基因,还呈现了该新种在batoense蚋物种组中的系统发育位置。该新种是老挝已知的第二个物种。
