Rhagonycha bimucronata sp. nov.

( Figs. 1-3 )

Type locality. China, Sichuan Province, Maoxian env., 1500 m a.s.l.

Type material. HOLOTYPE: J, ‘ China: Sichuan prov., Maoxian env., 1500 m, 29.vi.2003, S. Murzin lgt.’ ( NMPC) . PARATYPES: same data, 13 JJ 26 ♀♀ ( NMPC).

Description. Coloration. Body pale lemon yellow, elytra moderately transparent and darkened in posterior portion, tarsi and mandibles rusty, antennae chestnut brown, meso- and metasternum and abdomen black.

Male. Eyes protruding, head across eyes as wide as pronotum, temples straight, convergent posteriorly. Antennae reaching almost elytral apex, filiform. Surface of head very finely rug- ulose-lacunose, sparsely and finely yellow pubescent, matt. Pronotum ca 1.25 times as wide as long, its anterior margin widely rounded, anterior corners rounded, lateral margins strongly divergent posteriorly, straight, only very slightly sinuate before sharp posterior corners, posterior margin widely rounded. Surface of pronotum very finely and very shallowly ruguloselacunose, very sparsely and finely yellow pubescent, lustrous. Elytra rather widened posteriorly, elytral nervation not developed, surface of elytra finely rugulose-lacunose, sparsely and finely yellow pubescent, semilustrous. Aedeagus as in Figs. 1-3 .

Female. Body wider than in male. Eyes smaller and less protruding, head across eyes moderately narrower than pronotum, antennae reaching two thirds of elytral length. Pronotum ca 1.33 times as wide as long.

Length J ♀: 5.3-7.5 mm.

Differential diagnosis. Given the shape of the aedeagus, Rhagonycha bimucronata sp. nov. is related to R. flava Wittmer, 1997 and R. bifurcata Wittmer, 1997 , both occurring in Sichuan; it differs from the former in the rounded apex of the paramere in lateral view and from the latter in the narrower and shorter branches of the dorsal part of the aedeagus (cf. WITTMER 1997).

Etymology. Derived from Latin bis = double and mucro = spike; named in reference to the shape of the branches of the dorsal part of the aedeagus.

Distribution. China: Sichuan.
