Description.
Male (
Fig. 1
A). Head black, mandibles dark brown, maxilla, labium and gula yellow, darkened at maxillary and labial palpi, antennae black, prothorax yellow, pronotum black, more or less yellow at margins and sometimes on posterior part of middle line, scutellum yellow, elytra black, legs black, yellow at coxae, trochanters and basal halves of femora, meso- and metasterna and abdomen yellow. Body densely covered with recumbent dark brown pubescence, mixed with slightly long semierect pubescence on elytra and a few long hairs along anterior margin of clypeus.
Head rounded, surface densely and finely punctate, lustrous; eyes distinctly protruding, head breadth across eyes distinctly wider than anterior margin of pronotum; terminal maxillary palpomeres widest nearly in middle, arcuate and sharp at apical halves of inner margins, rounded at apices; antennae extending to about basal two-fifths length of elytra, antennomeres II about 3 times as long as wide at apices, III slightly shorter than II, IV about twice as long as III, V‒XI each with an oblong to narrow longitudinal impression near middle of outer margin, XI slightly shorter than X and pointed at apices.

Scale bars: 1.0 mm.
Pronotum subquadrate, about 1.23 times as wide as long, anterior margin slightly arcuate, lateral margins nearly parallel, posterior margin arcuate and narrowly bordered, anterior and posterior angles nearly rectangular, disc convex at posterolateral parts, surface punctate like that on head, lustrous.
Elytra about 4.7 times longer than pronotum, 3.0 times longer than humeral width, lateral margins nearly parallel, disc coarsely and densely punctate, matt.
Aedeagus (
Figs. 3
A‒C): ventral process of each paramere narrow and nearly straight, with apex globally expanded on dorsal side and slightly hooked on ventral side in lateral view; conjoint dorsal plate of parameres slightly shorter than ventral processes, evenly narrowed apically and wider than distance between the ventral processes, largely and triangularly emarginated in middle of apical margin, each side distinctly convex at apical part of inner surface; laterophyses flattened and adhered to dorsal side of median lobe, with inner margins evenly diverging apically, outer apical angles widely triangular.

Female (
Fig. 1
B). Similar to male, but eyes less protruding, head breadth across eyes slightly wider than anterior margin of pronotum; antennae narrower and shorter, extending to basal one-fifth length of elytra, antennomeres V‒XI without impressions; pronotum about 1.17 times as wide as long, with lateral margins slightly diverging posteriorly, disc slightly convex at posterolateral parts; elytra about 2.9 times longer than humeral width, with lateral margins slightly diverging posteriorly. Abdominal sternite VIII (
Fig. 5
A) narrowly emarginated in middle of posterior margin, which is nearly truncated at apex of lateral portion beside middle emargination. Internal reproductive organ of genitalia (
Fig. 6
): vagina stout, with diverticulum and spermatheca situated at apex, median oviduct in middle of ventral side; diverticulum moderately long tube-shaped, slightly narrowed apically and rounded at apex; spermatheca long sac-shaped, slightly expanded apically and rounded at apex, which is nearly as long as diverticulum, and provided with a long and thin accessory gland near base; diverticulum and spermatheca surrounded with a strongly sclerotized ring at base, which is confluent in middle and extending to median oviduct on ventral side, the opening of spermatheca arising from middle of the sclerotized ring on dorsal side.
Body length: 17.0 ‒22.0 mm; width: 4.5‒6.0 mm.

Remarks.
In the original publication (
Fairmaire 1889
), this species was described on the female
type
located in “Thibet, Tatsiénlou” [now in
China
, Sichuan, Kangding]. In our study, materials including both sexes from the
type
locality were available, so we described the male and added some additional description for the female.
