The type specimens are deposited in the Department of Biology, Nankai University. The diagnosis of the new species is given as follows:Ceratocombus guizhouensis Ren et Yang, sp. nov. (figs. 1-7)Male macropterous, length of body 1.70 mm, width 0.75 mm. Length of head 0.14 mm, width 0.36 mm, with 3 pairs long hair (fig.1);length of antenn'al segments I : Ⅱ : Ⅲ : IV =0.06 : 0.17 : 0.72 : 0.46mm; rostrum light yellow, length 0.7 mm, reaching apices of posterior coxae. Length of pronotum 0.11 mm, width anterior margin 0.34 mm, posterior margin 0.56 mm, lateral margins straight, with short hairs, lateral angles rounded; collar notable; calli large, clearly delimited. Scutellum triangular, length 0.22 mm, width of base 0.29 mm. Fore wing elongate, slightly narrow, length 1.5 mm, 0.61 mm beyond apex of abdomen, venation as in fig 2, costa with short hairs, membrane areawith 3 cells. Posterior femora distinctly shorter than tarsi (0.37-0.60 mm); tarsus withtwo segments, length 0.34 mm.Genital segment of the male symmetrical as in fig.7, strongly sclerotized, structurevery complicated (fig.7), with 3 pairs of appendages. The 1st pair, namely, 8thlaterotergites (fig.3), long and free, at the sides of the segment, with longer hairs, its apex rounded. The 2nd pair,-namely, 9th laterotergites, broad, curved, lying on the dorsal surface of the segment, the apex biuncinatus towards the base (figs. 4,5,7). The 3rd pair, viz. paramere (figs. 6,7), with a subquadrangular basal part and the thin apical part, its apex hamulatus (fig. 6).Female macropterous, length of body 1.80 mm, width 0.80 mm. Tarsal formula 2-2-2. Genital segments slightly sclerotized ;however, 2nd velvulae strongly sclerotized.Holotype , allotype , Guizhou Province, Guiyang City (106.7E, 26.6 N), 7-IX -1988, at lights, Yang Chi-kun.The new species is closely related to Ceratocombus fasciatipennis Ren et Zheng in body form, colour and struc
