( Figs. 1–4, 13–14 )

Cladophyllus oberthuri Houlbert, 1912: 139 [type locality: Tsekou (in Lancang valleys, northwestern Yunnan)], figures for habitus, mandible, antenna, canthus, legs, scutellum and mesosternum; Mizunuma & Nagai 1994: plate 148, Fig. 111 , “ holotype ”; Boucher 1996: 73, lectotype designation; Fig. 3 , male head; Fig. 6 , male mentum; Fig. 9 , male pronotum; and Fig. 15 , male genitalia.

Cladophyllus flavus Didier, 1930: 126 [type locality: “Yunnan, Sseu-tch’ouan, Thibet” (no exact locality)]; Mizunuma & Nagai 1994: plate 148, Fig. 112 , “ holotype ”; Boucher 1996: 73, lectotype designation, synonymy.

Material examined. CHINA: Yunnan: 9 3, 4 ƤƤ, Diqing, Weixi County, Pantiange, ca. 2000m, 8.VII. 2010, Xiao-Dong Yang and Wen-Xuan Bi leg.; 2 3 ( CHH, CYXW), Diqing, Weixi County, above 2000m, VII. 2006, An-Ming Chen leg.

Identification. Boucher (1996) designated the lectotypes of both Cladophyllus oberthuri and C. flavus and considered them as synonyms; he described and illustrated the male genitalia for the first time. According to the original description and Boucher’s paper, C. oberthuri can be distinguished from C. bousqueti Boucher, 1996 by the more deeply bifurcated antennomere 10, the less transverse mentum, the blunter lateral angles of the pronotum and the markedly longer flagellum of the median lobe with apex not enlarged. The male specimens examined by us match all these characters for C. oberthuri .

The female of Cladophyllus oberthuri are here illustrated and described for the first time; they have been found inside decayed logs together with the male specimens.

Taxonomic notes. All three known species are allopatric in distribution: C. oberthuri is restricted to the Lancang valleys in northwestern Yunnan; C. bousqueti is distributed to the west of the Nujiang River and into northeastern Myanmar; C. nobuhikoi is restricted to the mountain ranges around China-Vietnam border. They are considered as separate because of the marked differences in male and female genitalia.

Distribution. northwestern Yunnan (Lancang valleys).
