Material. China, Yunnan Province: holotype, male, N Wexi City, right tributary of Lapugou River , 2.2 km E Jizong, c. 2705 m, N27°25΄5˝, E 99°22΄9˝, 6.VI.2015, leg. I. Belousov, I. Kabak, G. Davidian. ( ZISP) (damaged: 9 th –11 th right antennomeres and 5 th –11 th left antennomeres absent) .

Description. Male ( Figs 1, 2 ). Head, pronotum, scutellum and palpi dark brown to black lacking metallic luster, posterior side of labrum yellow, antennae dark brown, 1 st to 4 th antennomeres yellow beneath; elytra orange-yellow, impressions in apices orange-red with invagination inside yellow, appendages orange-brown. Ventral side of thorax black, abdominal ventrites with yellow comissure membranes, legs, coxae and trochanters black with comissure part yellow-brown, vesicles pale yellow, thorax mesepimere black.

Head narrow, twice slightly impressed just before the antennae, and with narrow interocular impression ( Fig. 3 ); covered with thin short goldish adpressed pubescence, the row of erect pale hairs is on the clypeus, and several black erect setae are on temples behind eyes; surface sparsely and finely punctuated with distinct microsculpture; labrum short, transversal; genae short, straight; eyes weakly protrudent, round. Palpi elongate, the 1 st segment is 1.5 times longer than the 2 nd, clavate, the 2 nd segment is 1.5 times shorter than the 3 rd, subtriangular, apical segment narrow and sinuate to the apex, subconic; surface shining with light short hairs. Antennae dentate; the 1 st segment slightly enlarged and clavate, twice longer than the 2 nd, the 3 rd is 1.3 times as long as the 2 nd, and 1.1 times as short as the 4 th; 4 th –8 th antennomeres are the same length and size, 9 th –11 th antennomeres absent, the 2 nd antennomere oval, remaining antennomeres triangular; antennomeres covered with thin light and short semi-erect hairs.

Pronotum equilateral, anterior margin arcuate, posterior straight, all angles rounded, with distinct depressions at the posterior angles ( Fig. 3 ); surface sparsely and finely punctured, microsculpture distinct, covered with dark fine and short adpressed pubescence.

Scutellum rectangular with rounded apex, small, almost completely hidden by the pronotum, flat; the surface shining, evenly punctured and pubescent with adpressed dark hairs.

Elytra parallel, narrow, not widened posteriorly; shoulders distinct; apices evenly rounded and strongly impressed ( Fig. 4 ), with elongate flat and rounded distal margin of the elytra near suture and appendages inside the impression; outer appendage lamellate and vertical, possessing curved hair tuft at the tip, located near suture, inner appendage thin, curved and consisting of two parts, pedicellum at base and an oval flat plate at apex; surface dull, looks chagrin, sparsely punctured and microsculptured, covered with fine, short goldish adpressed pubescence.

Wings well developed.

Legs long and thin, posterior femora extending over the elytral apices, posterior tibiae slightly curved outwards, covered with short adpressed dark hairs; claw tarsomeres bear elongate black setae on the upper side; tibiae thin, weakly expanded posteriorly, rounded; femora narrow, compressed, simple, all tarsi 5-segmented, narrow, 1 st –4 th tarsomeres in anterior legs, 1 st and 2 nd tarsomeres and 3 rd and 4 th tarsomeres in intermediate and posterior legs nearly equal in size, the 1 st or 2 nd tarsomeres are 1.5 times as long as the 3 rd or 4 th tarsomere in these legs; claws narrow, sharp, with distinct round pellucid lamellae at the base.

Ventral body surface sparsely and finely punctured with distinct microsculpture, shining, sparsely covered with fine, adpressed dark pubescence; metathorax slightly prominent, simple, lacking appendage of hair tuft. Pygidium (apical tergite) ( Fig. 5 ) subquadrate with rounded distal side, 1.3 as wide as long, anterior side evenly rounded; 8 th ultimate abdominal ventrite (apical sternite) ( Fig. 6 ) subtriangular, evenly narrowed and rounded at apex, with deep round emargination in the middle. Phallus ( Figs. 7 ) simple, strongly curved dorsally, widened posteriorly, with a sharp and curved downward apical lamella. Tegmen elongate, 2.2 times longer than wide, emarginate in the middle, with long thin appendages, slightly curved at the tips ( Fig. 8 ).

Length (holotype) 3.0 mm, width (at elytral base) 0.7 mm.

Female unknown.

Etymology. The species is named in honour of the famous entomologist Dr Aleksandr Georgievich Koval, All- Russian Institute of Plant Protection (FSBSI VIZR), Saint Petersburg, Russia, who pays particular attention to all material collected being available to study by specialists.

Diagnosis. The new species can be distinguished by its uniformly orange-yellow elytra, a black head and pronotum lacking metallic luster, and the shape of elytral impression and appendages in male ( Fig. 4 ); other differential characters are given in the Key below.
