Stenothemus sepiaceus sp. nov.

( Figs. 69-70 )

Type locality. China, Yunnan Province, Daxueshan mts., NW of Menghu (S of Licang), 2400 m a.s.l.

Type material. HOLOTYPE: J, ‘ China: Yunnan prov., Daxueshan mts. , NW Menghu (S Licang), 2400 m, 9.-10.v.2003, S. Murzin lgt.’ ( NMPC).

Description. Coloration. Head, prothorax, meso- and metasternum, legs and abdomen sienna, antennae sepia, antennomeres 1 and 2 with paler bases, elytra sepia.

Male. Eyes of moderate size, protruding, head across eyes ca 1.25 times as wide as pronotum, temples almost straight and convergent posteriorly. Antennae slightly exceeding three fourth of elytral length, antennomeres 4-10 slightly flattened and each with small, oval, semilustrous impression. Surface of head finely imbricate-punctate, with brown pubescence, matt on vertex and semilustrous anteriorly. Pronotum almost 1.2 times as long as wide, its anterior margin widely rounded, anterior corners rounded, lateral margins parallel-sided, slightly sinuate before rounded posterior corners, posterior margin widely rounded. Surface of pronotum very finely puncticulate-reticulate, sparsely and finely brown pubescent, semilustrous. Elytra parallel-sided, elytral nervation absent, surface of elytra finely rugulose-lacunose and brown pubescent, matt, semilustrous basally. Aedeagus as in Figs. 69 and 70 . Female unknown.

Length J: 5.6 mm.

Differential diagnosis. Stenothemus sepiaceus sp. nov. is, given the shape of the aedeagus and the pronotum, related to S. bezdeki from Laos, from which it differs in the semilustrous pronotum and base of the elytra and in a different shape of the dorsal part of the aedeagus (cf. ŠVIHLA 2004).

Etymology. Sepiaceus (Latin) = sepia, named in reference to the colour of the elytra.

Distribution. China: Yunnan.
