This study treats all of the known Chinese species of the genus Carcelia R. D. A total of 73 species are presently recognized, among them 15 new species new and 2 that are newly reported from this country. All taxa are keyed and briefly diagnosed. The type species are kept in the Institute of Zoology, Chinese Academy of Sciences. Based on examinations of a large number of type and non type specimens, we found that Chinese species of Carcelia R. D. frequently show some inter or infra specific variations in body chaetotaxy. In some cases sexual dimorphism is also evident. For example, the ventral seta of mid tibia are absent in the male of C.rondaniella , but present in the female. In C.caudata, most specimens had 1 2 posterodoral setulae on hind coxa, but these were absent in a few of individuals(5 7%). Meanwhile, ocellar bristles in C.caudata and C.octava; and median discal bristles on 3rd and 4th abdominal tergites in C.dubia, C.lucorlum, C.hirtspila, C.vilicauda, C.clava, C.tibialis and C.latistylata are also strongly varied. In view of these observations it is clear that the presence or absence or developmental state of these setulae and bristles are unreliable specific or even subgeneric characters. As a result of study of these variations we divide the genus Carcelia R. D. into two subgenera: Senometopia Macquart and Carcelia (s. str.), the former is characterized by having bare hind coxae and the latter by having 1 2 setulae on the posterodorsal surface of the hind coxae.1 Carcelia (Senometopia) xishuangbannanica sp. nov. (Fig.59) ♂ Frons a little narrower than 1/2 eye width, ocellar bristle a little longer than upper reclinate orbital bristle, basal two segment of anntena and basicosta yellow, thorax black, with yellow stripes along its lateral and posterior sides, scutum with four pairs of postsutural dc bristles, scutellum entirely yellow, postpronotum with three basal setae in a more or less straight line. Legs entirely reddish yellow, claws and pulvilli of fore leg almost the same length of fourth plus fifth tarsomers together, mid tibia without ventral bristle, with one anterodorsal and two posterodorsal bristles, hind coxa bare. Abdomen yellow, with longitudinal anchor shaped black stripes along mid line dorsally and ventrally, fifth tergite and posterior 2/5\|3/5 of fourth tergite black, abdominal hairs dense and about 8\|9 rows on fourth tergite, claws and pulvilli of hind leg distinctly longer than its fifth tarsomere. Body length about 9?mm. ♀ Head with two proclinate orbital bristles on each side; claws of fore leg shorter than its fifth tarsomere. Holotype ♂, Xishuangbanna(1?700?m, 22°N, 100 80°E), Yunnan, 23 June 1958, by CHEN Zhi Zi. This species is related to C.orientalis Shima and C.subferrifera Walker, but differs from these in the fore tibia having two posterior bristles, the claws and pulvilli of fore leg almost equal in length to fourth and fifth tarsomeres together; scutum with yellow stripes along its lateral and posterior sides; scutellum entirely yellow, rather than with blackish base; abdominal hairs rather dense, about 8 9 rows on fourth tergite; cerci distinctly longer than surstyli, long triangular, with dense yellow brown hairs on dorsum, and apical part bare, bright and curved ventrally, surstyli nearly rectang was and a little curved ventrally, with dense setulae on lateral sides.2 Carcelia (Senometopia) jilinensis sp. nov. (Fig 60) ♂ Frons about 0 61 times as wide as eye in dorsal view, ocellar britles absent, epaulet and basicosta black, pollinosity on head goldish yellow, thorax black in ground color, with yellow stripes along its lateral and posterior sides, scutum with four pairs of postsutural dc , scutellum entirely yellow, pollinosity on abdomen thick, well distributed and grayish yellow; third and fourth tergites without bright black margins and with long and erect bristles and hairs, fourth tergite with irregular median discal bristles, legs black except t
