China (Sichuan, Hubei, Yunnan); India (Meghalaya); Laos (Haris 2014); Nepal (Gandaki); Thailand (Chiang Mai) (Fig. 6). This species is recorded from Nepal and Thailand for the first time. Remarks. The redescription of the species is based on the holotype kept in MNHN. The pictures of the female lancet were taken from a female collected from Hubei, China, which was compared in detail with the holotype. No distinct difference has been found between them including genitalia characters. C. rufidorsata is close to C. zhongi sp. nov. See the above key for the differences between the two species. Among the three species of Colochela, C. rufidorsata has the weakest body sculpture and punctation. Malaise (1937) stated in the original description of Colochela that the anal cell in forewing is with a short and perpendicular cross-vein at basal third. The examination of the holotype in MNHN (Paris) revealed that the anal cell in forewing of C. rufidorsata is without a cross-vein (Fig. 1 c). The female paratype of C. rufidorsata kept in USNM (Washington D. C.) does have a short anal cross-vein in both forewings (Figs 1 h–j) but the specimen is a female of C. zhongi sp. nov. We examined the male paratype of C. rufidorsata kept in USNM but overlooked the state of the basal anal cross-vein, so we do not sure whether the forewing of the male has basal anal cross-vein or not. In CNCI, a male specimen collected from Nepal during the Canadian Nepal expedition in 1967 refers to C. rufidorsata Malaise. The abdominal tergites are not microsculptured and are strongly shiny. The data of the specimen is: Nepal, Ktmd [Katmandu], Godavari, 5000’ [about 1,600 m], 31.VII.1967, Can. Nepal Exped. (Dr. H. Goulet, personal communication).
