Redescription. Male ( Fig. 3 ). Body black, except mandibles brown, antennomeres I brown on ventral sides, pronotum orange, slightly darkened at anterior margin or and posterior margin, abdominal sternite IX and tergite IX yellow. Body densely covered with dark brown to black pubescence, clypeus sparsely and pronotum, coxae, trochanters and ventral sides of femora and abdominal sternite IX and tergite IX densely with pale yellow pubescence, of which slightly longer on clypeus, pronotum and pro-legs than other parts.

Head sub-rounded, surface finely and densely punctuate, width across eyes distinctly wider than anterior margin of pronotum, eyes distinctly protruding; terminal maxillary palpomere nearly triangular, widest in middle, apical half of inner margin arcuate; antennae ( Fig. 11 ) extending to middle of elytra when reclined, antennomere II slightly longer than wide at apex, III −XI flattened, III −X slightly widened apically, long-triangular, VI longest, XI nearly parallel-sided and acute at apex, slightly longer than X.

Pronotum subquadrate, nearly as long as wide, widest near base, anterior margin arcuate, lateral margins diverging posteriorly and slightly sinuate, posterior margin nearly straight, anterior angles rounded, posterior angles nearly rectangular, disc slightly convex on posterolateral parts, surface finely and slightly sparsely punctuate than that on head.

Elytra about 4 times longer than pronotum, 3.5 times longer than width across humeri, humeral width distinctly wider than posterior margin of pronotum, outer margins nearly parallel, disc mat, coarsely and densely punctuate, present with two slightly distinct longitudinal costae near inner margins. Legs slender, all tarsal claws simple.

Abdominal sternite IX long-triangular. Aedeagus ( Figs. 20–22 ): ventral process of each paramere nearly straight, with apex rounded, almost as long as dorsal plate, dorsal plate with apical margin nearly straight, with inner angle slightly extended and bent ventrally, outer angle rounded, outer margin nearly straight, basal piece large, with outer margin nearly extending to bottom of the emargination between ventral process and dorsal plate; laterophyse with apex slightly hooked, nearly as long as ventral process of each paramere.

Female. Similar to the males, but eyes less protruding, antennae ( Fig. 12 ) shorter and narrower, extending to basal one-third length of elytra when reclined, pronotum wider than long, disc indistinctly convex, all tarsal claws simple, abdominal sternite VIII and tergite VIII yellow, sternite VIII ( Fig. 30 ) wide, with a middle and two lateral large emarginations at posterior margin, the middle emargination slightly shallower than lateral ones, the portion of posterior margin between middle and lateral emarginations obtuse at apex respectively.

Body length: 10.0− 10.5 mm; width: 2.2−2.4 mm.

Distribution. China (Fujian, Guangxi).

Remarks. This species was synonymized with L. kiontochananus by Wittmer (1982). In the present study, it is reinstated to be a valid species, since its abdominal sternite VIII and antennae of the holotype are found to be different from that of the latter species. Furthermore, the aedeagus of the additional material is shown to be definitely different. Therefore, we suggest L. perroudi ( Pic, 1937) be resurrected from synonymy with L. kiontochananus .
