Lycocerus unguiformis sp. nov.

Figs. 4 View FIGURES 1 – 9. 1 – 9 , 35–37 View FIGURES 28 – 37. 28 – 29 .

Type locality. China, Sichuan province, Emei Shan Mts., 2400–2800 m a.s.l.

Type material. Holotype, male ( NMEG), “ CHINA, Sichuan, Emei Shan, 2800– 2400 m, 22.–23.VII.1992, leg. C. Holzschuh [white label, printed]”.

Description. Coloratoin ( Fig. 4 View FIGURES 1 – 9. 1 – 9 ). Body entirely sooty, mandibles and claws sepia.

Male. Eyes comparatively small but protruding, head across eyes by ca one fifth wider than pronotum, margins of head behind eyes nearly straight, converging posteriorly. Antennae reaching almost elytral apex, filiform, antennomeres moderately flattened, antennomeres 4–10 with very small longitudinal impression. Surface of head very finely punctate, with fine, brown, semirecumbent pubescence, semilustrous. Pronotum longer than wide by ca one fifth, anterior margin convex, anterior corners distinct, obtuse, lateral margins diverging posteriorly, shallowly sinuate in anterior half, posterior corners distinct, nearly rectangular, posterior margin only slightly convex. Surface of pronotum punctate and pubescent like that of head, semilustrous. All claws simple. Elytra very slightly narrowing posteriorly, surface of elytra finely rugulose, with fine, semirecumbent brown pubescence, matt, elytral venation slight but visible. Aedeagus as in Figs. 35–37 View FIGURES 28 – 37. 28 – 29 .

Female unknown.

Length (male). 13.8 mm.

Differential diagnosis. Lycocerus unguiformis sp. nov. is very similar in body form and coloration to Lycocerus milosi ( Švihla, 2004) (Sichuan) , but it is considerably larger and with eyes comparatively smaller than in the latter species. Further distinguishing characters can be found in the shape of the aedeagus, apices of divided portions of the dorsal part of it are shallowly emarginate with slightly, but distinctly protruding inner corners, and laterophyses are basally dilated in lateral view in L. unguiformis sp. nov. (cf. Švihla 2004).

Etymology. Derived from Latin unguiculus - claw and forma - shape, named in reference to the shape of the laterophyse, which is very similar to the claw in lateral view.

Distribution. China: Sichuan province.
