Type material.

Holotype ♂ (MHBU): CHINA, Yunnan, Yunlong, Tianchi Nat. Res., 9.VII.2011, leg. Hao-Yu Liu. Paratype: 1♂ (MHBU): same data as holotype. [Both transliterated from Chinese labels].

Distribution.

China (Yunnan).

Description.

Male (Fig. 2). Body black, mandibles dark brown, pronotum red, with a large black marking in center of disc, elytra red, black almost along the whole length of the first and second elytral interstices, more or less darkened at the third and fourth elytral interstices.

Head evenly narrowed behind eyes, surface densely and finely punctate, semilustrous, covered with dense, fine, yellowish brown decumbent pubescence; eyes moderately protruding, head width across eyes moderately wider than anterior margin of pronotum; terminal maxillary palpomeres long-triangular, arcuate and sharp at apical one-third length of inner margins; antennae (Fig. 8) extending to apical one-third length of elytra, antennomeres II nearly as long as wide at apices, III–XI flattened, III–VIII obliquely widened apically, nearly long-triangular, III about twice as long as wide at apices, IV slightly longer than III, IX–XI nearly parallel-sided, XI slightly longer than X and pointed at apices, IV–XI each with an oval to round smooth impression at apical part of outer margin.

Pronotum nearly as long as wide, widest near posterior margin, anterior margin arcuate, anterior angles rounded, lateral margins slightly diverging posteriorly, posterior angles rectangular, posterior margin slightly arcuate and narrowly bordered, disc moderately convex at posterolateral parts, surface punctate and pubescent like that of head, semilustrous.

Elytra about 5.8 times longer than pronotum, 4.0 times longer than humeral width, which about one-third wider than posterior margin of pronotum, lateral margins nearly parallel, elytral venations moderately developed, slightly costate.

Pro- and meso-outer tarsal claws each with a basal projection.

Abdominal sternite IX long-triangular. Aedeagus (Figs 19-21): ventral process of each paramere normal and rounded at apex, distinctly narrowed at base and slightly bent dorsally in lateral view; dorsal fig distinctly shorter than ventral process, evenly narrowed apically, with inner angle widely rounded, outer angle obtuse-angled, inner margin nearly arcuate, apical margin rounded, around with long pubescence; laterophyse with apex pointed laterodorsally to outer angle of dorsal fig.

Female. Unknown.

Body length (males): 8.0-9.0 mm; width: 1.8-2.0 mm.

Etymology.

This specific name is derived from Latin longus (long) and hirtus (hairy), referring to its aedeagus: dorsal fig of each paramere covered with long pubescence along apical margin.

Diagnosis.

This species is similar to Lycocerus gracilicornis sp. n., but the antennomeres III–VIII widened apically, nearly long-triangular; elytral venation moderately developed, slightly costate; aedeagus: dorsal fig of each paramere evenly narrowed apically, inner margin arcuate, apical margin around with long pubescence.
