Cephennodes (s. str.) bicolor Jałoszyński, 2007a: 48 .

Material studied. CHINA (YUNNAN Prov.): 2 ♂♂, Yunnan, Dali Bai Nat. Aut. Pref., Diancang Shan , W of Dali, 25°41.09’N, 100°06.32’E, 3000-3200 m, sifted from litter debris in a cleft in mixed forest, 27.V.2007, leg. A. Pütz (cAP, cPJ) .

Remarks. Cephennodes hamatus was described based on specimens collected in Yunnan, Dali Bai Nat. Aut. Pref., Diancang Shan, 3 km W of Dali old town, in pine forest at „Cloud Road”, right upper chairlift station, 25°41.1’N, 100°06.8’E, 2650–2750 m, sifted from pine needles, dry moss, in ditches, and from mushrooms. The newly recorded specimens come from a close proximity, but the collecting site is at a higher altitude.

Cephennodes bicolor is a relatively unremarkable species, difficult to identify. Fully pigmented males ( Figs 57– 58 ) are not so ‘ bicolor ’ as the specimens in the type series, but still the head and pronotum is somewhat darker than the elytra. The main diagnostic characters are: body slender; antennomere 6 slightly asymmetrical, so that antennae appear as slightly kinked ( Fig. 58 ; in the specimen showed in Fig 57 antennae were forcefully straighten up and glued to mounting card); legs, elytra and other body parts unmodified; aedeagus with a pair of small rounded lobes in distolateral regions of the capsular region; apical structures distad the lobes longer than wide; and parameres with slightly modified apices ( Figs 63–64 ), with a rapid narrowing forming a small lateral ‘platform’ where a short and thin subapical seta is inserted, and the apex with a longer and thicker seta.
