Simulium (Gomphostilbia) khelangense is described on the basis of females, collected by a sweeping net in Lampang, Phitsanulok and Chiang Mai Provinces, Thailand. This new species is placed in the subgroup of the species-group in the subgenus Gomphostilbia Enderlein by having the antenna with eight flagellomeres, pleural membrane bare, and female subcosta lacking hairs. It is similar to Pramual & Tangkawanit from Thailand in the same subgroup but is barely distinguished from the latter species by the head width relative to the greatest width of the frons and length of the labrum relative to the clypeus. A genetic analysis using the COI gene sequences similarly shows that is most closely related to , with a genetic distance of 1.23-2.81%. A revised key to identify females of 14 species of the species-group is provided.
克朗蚋（Gomphostilbia属）是根据在泰国南邦府、彭世洛府和清迈府用扫网采集的雌性标本描述的。该新物种被归入Gomphostilbia亚属Enderlein种组的一个亚组，其触角有八个鞭节，胸膜膜裸露，雌性亚前缘脉无毛。它与同一亚组中来自泰国的普拉穆阿尔蚋和坦卡瓦尼特蚋相似，但通过相对于额部最宽处的头部宽度以及相对于唇基的上唇长度，可与后一种勉强区分开来。使用COI基因序列进行的遗传分析同样表明，克朗蚋与普拉穆阿尔蚋关系最为密切，遗传距离为1.23 - 2.81%。提供了一个修订的检索表，用于鉴定该种组14个物种的雌性个体。
