Body blackish; antennae with scape reddish brown, becoming darker apically, antennomeres II to XI mostly light brown except for extreme apices of III to XI which are dark brown, but become less distinct toward apical antennomeres; legs mostly reddish brown, except for extreme apices of femora, extreme bases and apices of tibiae, and tarsi which are dark brown. Head and pronotum sparsely covered with white to yellowish pubescence, relatively dense and dark on antennal tubercles. Antennae with scape clothed with fine brown pubescence; antennomeres III to XI clothed with fine pale pubescence on basal parts. Scutellum densely clothed with yellowish pubescence, obscuring integument. Elytra covered with sparse pale pubescence forming mottled pattern. Legs and ventral surface moderately covered with pale pubescence, relatively dense on extreme apices of femora. Head slightly wider than pronotal base; frons and vertex deeply and coarsely punctate; eyes weakly emarginate; lower eye lobes vertical, ca. 2.0 times as long as width, 2.2 times as long as genae. Antennae 2.1–2.2 times as long as body length; scape clavate, broadest near apical third, smooth on surface, without apical cicatrix; antennomere III longest, 1.7 times as long as scape, 1.3 times as long as IV, antennomeres IV to X gradually decreasing in length. Pronotum cylindrical, subequal to basal width; each side provided with short lateral spine slightly before mid-length; disk as deeply and coarsely punctate as head, with exception of smooth bases of lateral spines, with three weakly elevated calli arranged in inverted triangle. Scutellum semicircular. Elytra elongate, 2.1 times as long as humeral width, 1.7 times wider than pronotal base; subparallel-sided in basal two thirds, then gradually convergent toward conjointly rounded apices; disk provided with a few granules in basal sixth, deeply and coarsely punctate throughout, punctures comparatively sparser than those on head and pronotum and becoming shallower near apical one fourth. Hindwings developed. Legs moderately long, femora strongly clavate. Male genitalia. Tergite VIII (Fig. 6a) roughly trapezoid with apical margin bearing sparse long setae. Tegmen (Fig. 6b) moderately curved in lateral view, rhombic in shape and widest near middle in ventral view; lateral lobes thickened at bases, provided with fine short setae on apices. Median lobe (Fig. 6c) robust with subacute apex, subequal to length of tegmen, moderately curved in lateral view. Endophallus in everted condition (Fig. 6d) arched, long and slender, about three times as long as median lobe; moderately curved ventrally before midlength; MPH subdivided into MT, CT and PB by weak constrictions; relative lengths of APH: MPH: BPH: PB: CT: MT = 1.0: 4.7: 0.8: 0.7: 1.4: 2.8. MT roughly cylindrical, CT provided with small ventral swelling near midlength, PB moderately swollen; APH elongate, gradually constricted distally, with developed bb; apical furrow with internal membrane developed; spicules mainly distributed on most parts of CT and surround ab; ejaculatory ducts paired, gn situated at dorsal side of bb which is associated with pair of long rod-like sclerites (Fig. 6e). Female (Fig. 4). Body length 9.9–13.5 mm, elytral maximum width 3.2–4.5 mm. Similar to male in general appearance except for the following: the main pubescence of body light brown, body relatively stouter, antennae ca. 1.5–1.6 times as long as body length, elytra broadest in apical two fifths and legs relatively shorter. Differential diagnosis. This new species is somewhat unique even among Lamiini by the main pubescence of body showing sexual dimorphism (pale in male and light brown in female). Additionally, it can be readily distinguished from F. griseofasciatus by the scape distinctly clavate, eyes only weakly emarginate and elytra without transverse bands of dark pubescence. The clavate scape of this species may be confused with members of the genus Rhodopina. However, the tarsi are pentamerous in Rhodopina. This species can be distinguished from members of Granulorsidis by the scape lacking a cicatrix. However, the resemblance of the endophallic structures of this new species, F. griseofasciatus and Granulorsidis cf. puncticollis (cf. Figs 5–7d) indicates potentially more complex relationships between these two genera which require further study. Etymology. The new species is dedicated to our friend, Mr. Chao Li, the collector of the holotype of the new species. The specific epithet is a noun in the genitive case. Distribution. China: Yunnan (Pingbian County).
