Figs. 1 View FIGURE 1 C, 2E, 4D‒F

Type material. Holotype male ( IZAS): CHINA, Guizhou, Zunyi, Neiyang, Kuankuoshui Nat. Res., 3.VI.2010, 1400‒1514m, leg. Z.L. Wang [transliterated from Chinese label].

Distribution. China (Guizhou).

Description. Male ( Fig. 1 View FIGURE 1 C). Head and mouthparts orange, slightly darkened at terminal maxillary and labial palpomeres, dark brown at apices of mandibles, antennae orange, darkened at antennomeres X‒XI, pronotum, scutellum and elytra black, legs orange, black at tarsi, prosternum orange, meso- and metasterna and abdomen black, light yellow at posterior margins of ventrites and apical part of sternite IX. Body densely covered with light yellow recumbent pubescence, mixed with slightly long semierect pubescence on elytra and along anterior margin of clypeus.

Head subquadrate, temples evenly narrowed posteriorly, surface matt, finely and sparsely punctate; eyes distinctly protruding, head breadth across eyes distinctly wider than anterior margin of pronotum; terminal maxillary palpomeres long-triangular, nearly widest at apical one-third, with inner margins arcuate and sharp at apical parts; antennae extending to elytral mid-length, antennomeres II nearly twice as long as wide at apex, III‒VII obliquely widened apically, III about twice as long as wide at apex, III‒VI each slightly roundly protruding at outer apical angle, VII ( Fig. 2 View FIGURE 2 E) about 1.5 times longer than wide at apex, straight at apical margins, obtuse at outer apical angles, VIII thickened and slightly widened apically, distinctly longer than wide at apex, distinctly protruding at inner apical angles, bald on surface of outer sides, with a shallow longitudinal groove at outer margin, IX lengthened and widened, about twice as long as maximal width, with outer margins triangularly protuberant and curled dorsally in middle, inner margins slightly arcuate, dorsal sides excavated and bald on the whole surface, also distinctly grooved along basal halves of outer margins, X‒XI parallel-sided, XI about one-third longer than X and pointed at apex.

Pronotum about 1.08 times as long as wide, anterior margin rounded, anterior angles rounded, lateral margins slightly sinuate and diverging posteriorly, posterior angles nearly rectangular, posterior margin arcuate and slightly bordered, disc moderately convex on posterolateral parts, surface semilustrous, punctate like that on head.

Elytra about 4.0 times longer than pronotum, 3.0 times longer than humeral width, lateral margins nearly parallel, disc surface semilustrous, rugulose-lacunose and finely punctate.

Legs with all tarsal claws bifid, upper claws nearly as long as lower claws.

Aedeagus ( Figs. 4 View FIGURE 4 D‒F): ventral process of each paramere evenly narrowed apically and slightly hooked at apex in ventral view; conjoint dorsal plate of parameres about half length of ventral processes, evenly narrowed apically, widely rounded at apical margin.

Female unknown.

Body length: 8.0 mm; width: 1.5 mm.

Diagnosis. This species is similar to F. septangula sp. nov. in the antennae, but can be easily distinguished from the latter by the body coloration and aedeagus: conjoint dorsal plate of parameres evenly narrowed apically and widely rounded at apical margin.

Etymology. The specific name is derived from the name of its type locality, Guizhou province, China.
