Distribution.

China (Sichuan).

Diagnosis.

This new species is similar to Fissocantharis semifumata (Fairmaire, 1889), but differs in the following characters: elytra with different coloration in both sexes, mixed black with light yellow in male, while entirely lightly yellow in female, lateral margins nearly parallel in male; aedeagus: conjoint dorsal plate of parameres with median emargination of apical margin slightly narrow, protuberances between median and lateral emarginations slightly wide.

Description.

Male (Fig. 7).Head reddish brown, clypeus light yellow, mouthparts dark brown, antennae black, pronotum and scutellum reddish brown, elytra black, light yellow at bases and lateral margins, of which inner margins wider than outer ones, legs black, femora light brown at inner sides, ventral parts of thorax and abdomen black, last 2 abdominal ventrites light yellow.

Head subquadrate, evenly narrowed behind eyes, dorsum densely and finely punctate, eyes moderately protruding, breadth across eyes slightly wider than anterior margin of pronotum, terminal maxillary palpomeres long-triangular, widest near apices, antennae filiform and simple, extending to apical one-third of elytra, antennomeres II about 1.5 times as long as wide at apices, III one-third longer than II, V longest, XI slightly shorter than X.

Pronotum subquadrate, slightly wider than long, widest at base, anterior margin arcuate, lateral margins diverging posteriorly, posterior margin almost straight, anterior angles rounded, posterior angles nearly vertical, disc densely and finely punctate as that on head, distinctly convex on posterolateral parts.

Elytra about 5 times longer than pronotum, 4 times longer than humeral width, lateral margins nearly parallel, disc slightly sparsely and largely punctate than that on pronotum.

Legs: all tarsal claws bifid, with upper claws almost as long as lower ones.

Aedeagus (Figs 20-22): conjoint dorsal plate of parameres with median emargination of apical margin slightly narrow and deeper than lateral ones, protuberances between median and lateral emarginations slightly wide and rounded at apices, about half length of ventral process of each paramere in dorsal view; ventral process of each paramere narrow, slightly turned outwards at apex in lateral view; median lobe without any sclerotized projection in dorsum.

Female. Body larger, eyes less protruding, antennae narrower and shorter than that of males, pronotum distinctly wider than long, elytra entirely light yellow, with lateral margins diverging posteriorly, tarsal claws with lower claws distinctly shorter than upper ones.

Body length: 8.0-11.0 mm; width: 1.5-2.5 mm.

Etymology.

This new specific name is derived from Latin bi- (two) and color (coloration), referring to it being sexually dimorphic in coloration of elytra.
