Type material.

Holotype ♂ (IZAS): CHINA: Guangxi, Napo, Nonghua, 1000m, 14.IV.1998, leg. C.S. Wu.

Description.

Male (Fig. 1C). Head black, mouthparts blackish brown, light brown at bases of mandibles and labium, antennae black, yellow at ventral sides of antennomeres I‒II, prothorax yellow, pronotum 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 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 posteriorly, 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 filiform, almost extending to apical one-third length of elytra, antennomeres II slightly longer than wide at apices, III‒XI parallel-sided, III about twice as long as II, IV‒XI each with a narrow longitudinal smooth impression at basal part of outer margin, IV about one-third longer than III, XI 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 posterolateral parts, surface semilustrous, punctate like that on head.

Elytra about 3.7 times longer than pronotum, 3.0 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 (Figs 4A‒C): conjoint dorsal plate of parameres greatly reduced, slightly emarginated in middle of apical margin; ventral process of each paramere evenly narrowed apically, largely hooked at apex.

Female. Unknown.

Body length: 6.0 mm; width: 1.5 mm.

Diagnosis.

This species is similar to Fissocantharis sinensis , but can be distinguished by the antennomeres IV‒XI each with a narrow longitudinal smooth impression along basal part of outer margin in male; aedeagus: conjoint dorsal plate of parameres greatly reduced, slightly emarginated in middle of apical margin.

Distribution.

China (Guangxi).

Etymology.

The specific name is derived from Latin mimus (similar, imitating something), referring to its similarity to Fissocantharis sinensis (Wittmer, 1988).
