Redescription.

Male (Fig. 1A). Head black, mouthparts blackish brown, light brown at bases of mandibles and labium, antennae black, yellow at ventral sides of antennomeres I‒II, prothorax orange, pronotum sometimes with a large black marking in middle of disc, which extending from anterior to posterior margin, scultellum black, elytra dark purple, with weak metallic shine, legs black, yellow at pro-coxae, trochanters and basal parts of femora, meso- and metasterna and abdomen black. Body densely covered with short decumbent light brown pubescence, also mixed with slightly long semierect pubescence along anterior margin of labrum and on disc of elytra.

Head subquadrate, temples evenly narrowed posteriad, surface semilustrous, finely and densely punctate; eyes strongly protruding, head breadth across eyes distinctly wider than anterior margin of pronotum; maxillary palpomeres IV longer than wide, widest at apical one-third, arcuate and sharp at apical parts of inner margins; antennae almost extending to apical one-third length of elytra, antennomeres II slightly longer than wide at apices, III‒X slightly flattened and obliquely widened apically, III about twice as long as II, IV slightly longer than VIII, V‒VIII each with a longitudinal smooth impression at apical part of outer margin, XI parallel-sided, slightly longer than X and pointed at apices.

Pronotum about 1.10 times longer than wide, widest near base, anterior margin rounded, anterior angle rounded, lateral margins sinuate, slightly diverging posteriad, posterior angle nearly rectangular, posterior margin arcuate and slightly bordered, disc distinctly convex on postero-lateral parts, surface semilustrous, punctate like that on head.

Elytra about 3.7 times longer than pronotum, 2.8 times longer than humeral width, lateral margins nearly parallel, disc surface semilustrous, rugulose-lacunose and finely punctate.

All tarsal claws bifid, upper claws nearly as long as lower claws.

Aedeagus (Fig. 3A‒C): conjoint dorsal plate of parameres well-developed, about half length of ventral processes, nearly parallel-sided, with apical margin tapered apically; ventral process of each paramere evenly narrowed apically, largely hooked at apex.

Female. Similar to male, but eyes not so protruding; antennae shorter, extending to elytral mid-length, antennomeres III‒X nearly parallel-sided, V‒VIII without impressions; pronotum slightly wider, about 1.05 times longer than wide, moderately convex at posterolateral parts of disc; legs black at profemora. Abdominal sternite VIII (Fig. 8A) slightly emarginated on both sides of posterior margin, middle part between lateral emarginations slightly acute at apex, latero-apical angles widely rounded. Internal organ of reproductive system (Fig. 9A): 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 distinctly thicker and shorter than diverticulum; spermatheca composed of a spiral tube which is distinctly longer than 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: 6.5‒8.0 mm; width: 1.2‒1.7 mm.

Distribution.

China (Guangxi, Sichuan).

Remarks.

In the original publication ( Wittmer 1988), some characteristics of antennae for the male is not indicated, which however is important for diagnosis of Fissocantharis species. Herein it is redescribed and also provided with some supplementary characters for abdominal sternite VIII and genitalia of the female.
