Cephennodes (s. str.) hamatus Jałoszyński, 2007a: 51 View in CoL . Material studied. CHINA (YUNNAN Prov.): 3 ♂♂, Yunnan, Nujiang   GoogleMaps , Lisu Aut. Pref., Gaoligong Shan   GoogleMaps , valley 18 km W Gongshan, 3020 m, 27º47’54’’N, / 98º30’13’’E, mixed forest, litter, moss, wood sifted, 7.VI.2007, M. Schülke (MNB, cPJ); 1 ♂, same data except for leg. A. Pütz (cAP).

Remarks. Cephennodes hamatus was described based on specimens collected in Nujiang Lisu Aut. Pref., Gongshan Co., Gaoligong Shan, 3000–3050 m, 27°47.90’N, 98°30.19’E ”, in a valley with coniferous forest with Rhododendron and broad-leaved bushes, sifted along creek and snowfields from litter, moss and dead wood. The newly recorded specimens come from a close proximity.

Cephennodes hamatus is one of the most easily identifiable species of the C. excavatus group.Males have a minute ventral denticle on the protarsomere 5 (illustrated in Jałoszyński (2007a): fig. 75), the protibia with a submedian mesal thickening ( Fig. 48 View FIGURES 48–56 ), and conspicuously modified elytra ( Figs 49–51 View FIGURES 48–56 ), not only with apical asetose impressions accompanied by setal penicilli, but also with large patches of modified setae on slightly flattened posterolateral regions. The distal region of the aedeagus is somewhat variable; constant features, visible also when endophallic structures are everted ( Figs 52–55 View FIGURES 48–56 ) are: a pair of rounded lobes in distolateral regions of the capsular region (clearly visible in ventral view), only slightly asymmetrical, triangular ventral apical plate about as long as broad and with a pointed apex, and parameres with unmodified apices ( Fig. 56 View FIGURES 48–56 ) bearing a pair of apical setae of similar lengths. External characters of males are more important for correct identification than the rather unremarkable aedeagus.
