Cephennodes spinosus Jaloszynski

Cephennodes (s. str.) spinosus Jałoszyński (Figs 32–37) Cephennodes (s. str.) spinosus Jałoszyński, 2007a: 54. Material studied. 1 ♂, Yunnan, Nujiang Lisu Aut. Pref., Gaoligong Shan, valley 18 km W Gongshan, 3020 m, 27º47’54’’N, 98º30’13’’E, mixed forest, litter, moss, wood sifted, 6.VI.2007, leg. M. Schülke; 1 ♂, 3 ♀♀, Yunnan, Nujiang Lisu Aut. Pref., Gaoligong Shan, valley 21 km W Gongshan, 27º47’03’’N, / 98º27’39’’E, 3320 m, moss, alder, bamboo, Rhodod., sifted, 6.VI.2007, leg. M. Schülke (MNB, cPJ). Remarks. Cephennodes spinosus was described based on a male and female collected in Nujiang Lisu Aut. Pref., Gongshan Co., Gaoligong Shan, valley, 3000–3050 m, 27°47.90’N, 98°30.19’E, in a coniferous forest with Rhododendron and broad-leaved bushes, sifted from leaf litter, moss and dead wood along a creek and snowfields. The newly examined specimens come from close proximities of this locality. The most conspicuous and unique diagnostic character of this species is a subtriangular process, a mucro, on the posterior margin of the male sternite VI (Fig. 35). Although the aedeagus, as in most members of the C. excavatus group, shows some variability in the shape of distal projections (see Figs 36–37, vs. figs 88–90 in Jałoszyński (2007a)), there is no doubt that all examined specimens belong in the same species. Fully pigmented specimens (Fig. 32) have dark brown, nearly black head and pronotum and distinctly lighter, reddish-brown elytra with infuscate suture, and males have a large and unique set of secondary sexual characters: antennomere 7 enlarged; protibia with a submedian mesal broadening; metatibia curved; elytral apex modified (Figs 33–34); and sternite VI with the posteromedian mucro (Fig. 35). Although the apical region of the aedeagus shows some variability within the studied sample, the presence of a pair of distolateral rounded lobes on the capsular region, and the conspicuously modified parameral apices, each with a subapical lateral process, are constant features.
