Simulium (Asiosimulium) furvum sp. nov. (Diptera: Simuliidae) is described from female, male, pupal, and larval specimens collected from Maewa National Park, Lampang Province, Thailand. This new species represents the fourth member of the subgenus Asiosimulium Takaoka & Chochoote, one of two small black fly subgenera endemic in the Oriental Region. It is characterized by a pear-shaped spermatheca in the female; a ventral plate in the male with a laterally compressed median keel directed ventrally and with a deep notch posteromedially, and aedeagal membrane with stout spines; and by 22 gill filaments in the pupa. Taxonomic notes are provided to separate this new species from three known species, Simulium (Asiosimulium) oblongum Takaoka & Choochote and Simulium (Asiosimulium) wanchaii Takaoka & Choochote, both from Thailand, and Simulium (Asiosimulium) suchitrae Takaoka from Nepal.
Simulium (Asiosimulium) furvum sp. nov.（双翅目：Simuliidae）是从泰国南邦府 Maewa 国家公园采集的雌性、雄性、蛹和幼虫标本中描述的。这个新物种代表了两个在东洋地区特有的小黑蝇亚属之一的 Asiosimulium Takaoka & Chochoote 亚属的第四个成员。它的特征是雌性具有梨形的受精囊；雄性的腹板具有侧向压扁的中央龙骨，指向腹侧，并有一个深的后中部凹陷，以及膜翅目带有粗壮刺的膜；蛹有 22 根鳃丝。提供了分类学注释，以将这个新物种与三种已知物种，Simulium (Asiosimulium) oblongum Takaoka & Choochote 和 Simulium (Asiosimulium) wanchaii Takaoka & Choochote，均来自泰国，以及 Simulium (Asiosimulium) suchitrae Takaoka 来自尼泊尔。
