Figs. 5 View FIGURES 1 – 9. 1 – 9 , 38–40 View FIGURES 38 – 50. 38 – 40 .

Type locality. Northern Thailand, Chiang Mai province, Chiang Mai, Mt. Doi Pui, 1400–1500 m a.s.l.

Type material. Holotype ( NHMB), male, “N. THAILAND, Chiang Mai, Mt. Doi Pui, 1400–1500 m, 8-V- 1982, T. Shimomura leg. [white label, printed]”.

Description. Coloration ( Fig. 5 View FIGURES 1 – 9. 1 – 9 ). Head, sternal part of thorax and elytra black, mandibles and claws sienna, antennae, pronotum, legs and ventral part of abdomem sooty.

Male. Eyes large and protruding, head across eyes slightly wider than pronotum, sides of head behind eyes very slightly concave, strongly converging posteriorly. Antennae reaching almost elytral apex, antennomeres moderately widened and flattened, antennomeres 4–10 with very small, oval, semilustrous impression. Surface of head finely and densely punctate, with brown, fine, semirecumbent pubescence, matt. Pronotum very slightly wider than long, anterior margin convex, anterior corners quite rounded, lateral margins straight, very slightly concave in anterior half, posterior corners sharp, nearly rectangular, posterior margin widely convex, very slightly sinuate before posterior corners. Surface of pronotum very finely coriarious-punctate, with brown, fine, semirecumbent pubescence, matt, velvety. Claws simple. Elytra parallel-sided, surface of elytra sculptured and pubescent like that of head, matt, velvety, elytral venation moderately costate. Aedeagus as in Figs. 38–40 View FIGURES 38 – 50. 38 – 40 .

Female unknown.

Length (male). 7.7 mm.

Differential diagnosis. Lycocerus nigrosericeus sp. nov. can be because of its coloration (especially dark abdomen) compared with Lycocerus milosi ( Švihla, 2004) (Sichuan) , from which it differs by moderately widened and flattened antennae, comparatively shorter pronotum, velvety elytra, slightly curved parameres and nearly truncate apices of divided portions of dorsal part of the aedeagus (cf. Švihla 2004).

Etymology. Derived from Latin niger = black and sericeus = silky, named according to the surface of pronotum and elytra.

Distribution. Northern Thailand.
