Distribution. China (Zhejiang, Anhui).

Description. Male ( Fig. 1 View FIGURE 1 D). 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, slightly darkened at tarsi, prosternum yellow, meso- and metasterna and abdomen black, yellow at lateral margins of abdominal 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 slightly 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 part; antennae extending to elytral mid-length, antennomeres II nearly twice as long as wide at apex, III‒VII obliquely widened apically and distinctly roundly protruding at outer apical angles, III about one-third longer than II, IV slightly shorter than III, VII ( Fig. 2 View FIGURE 2 F) widest, slightly longer than wide at apex, VIII slightly shorter than VII, distinctly protruding at inner angles, bald on surface of outer sides and ridged at outer margins, IX lengthened and widened, parallel-sided, about twice as long as wide, oblongly concaved and bald on outer parts of dorsal sides, X‒XI parallel-sided, XI about one-third longer than X and pointed at apex.

Pronotum about 1.10 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 matt, punctate like that on head.

Elytra about 4.1 times longer than pronotum, 3.3 times longer than humeral width, lateral margins nearly parallel, disc surface semilustrous, rugulose-lacunose and finely punctate.

Aedeagus ( Figs. 4 View FIGURE 4 G‒I): ventral process of each paramere abruptly narrowed apically and largely hooked at apex in ventral view; conjoint dorsal plate of parameres about one-third length of ventral processes, strongly obliquely narrowed apically, narrowly rounded at apical margin.

Female. Similar to male, but eyes less protruding, antennae filiform and black, antennomeres I‒II orange, pronotum slightly convex on disc, legs with lower claws distinctly shorter than upper claws. Abdominal sternite VIII ( Fig. 5 View FIGURE 5 C) moderately and subtriangularly emarginated on both sides of posterior margin, middle portion between lateral emarginations rounded at apex and slightly longer than lateroapical angles, which are rounded at apices. Internal organ of reproductive system ( Fig. 6 View FIGURE 6 C): vagina stout and abruptly narrowed and extended into a long duct above median oviduct; diverticulum and spermathecal duct arising from the end of the long duct of vagina; diverticulum moderately long, thin and spiral; spermathecal duct slightly thicker and shorter than diverticulum; spermatheca composed of a spiral tube which is nearly as long as diverticulum, provided with a very long and thin accessory gland which is much longer than the spiral tube of spermatheca; median oviduct situated in middle of vagina.

Body length: 7.0‒9.0 mm; width: 1.2‒1.7 mm.

Diagnosis. This species is similar to F. pallidiceps ( Pic, 1911) in the body coloration and shapes of aedeagi, but differs in the characteristic antennae of male, of which antennomeres III‒VII obliquely widened apically and distinctly roundly protruding at outer apical angles, VIII distinctly protruding at inner angles, bald on surface of outer sides and ridged at outer margins, IX lengthened and widened, parallel-sided, oblongly concaved and bald on outer parts of dorsal sides, while in the latter species, the antennae of male are filiform and simple.

Etymology. The specific name is derived from Latin novem (ninth) and oblongus (oblong), referring its antennomeres IX oblongly concaved on outer parts of dorsal sides in male.
