Otostigmus consonensis sp. nov. was described from Vietnam, and O. sulcipes Verhoeff, 1937 was recorded for the first time in this country. The new species can be recognized by having 18 antennomeres including 2.32.5 glabrous basal ones, three coxosternal teeth, tergites 520 with complete paramedia sutures, sternites with incomplete paramedian sutures, and the ultimate leg with 1115 prefemoral spines. The fragment of the COI gene was extracted for each species; thus, a new species and a record of O. sulcipes were supported by the COI genetic distances and the corresponding phylogenetic analysis.
钝尾丝角蝇 Otostigmus consonensis sp. nov. 被描述于越南，而 O. sulcipes Verhoeff, 1937 也在该国首次被记录。该新种可通过具有 18 节触角，包括 2.32.5 个无毛的基底节，三个胸侧板齿，腹板 520 与完整的侧缝线，腹板具有不完整的侧缝线以及具有 1115 个前股刺的最后一个腿来识别。从每个物种中提取了 COI 基因片段；因此，COI 遗传距离和相应的系统发育分析支持了一个新种和 O. sulcipes 的记录。
