One new species,
The recent visit of the first author to the IZAS Collection (Institute of Zoology, Chinese Academy of Sciences, Beijing), enabled the identification of many
See “Diagnosis” below.
Ground integument color bluish green, more intensely bluish and with long silvery pubescence underneath; antennae and legs bluish black; tarsi black, except slightly reddish onychium; head and pronotum shiny golden green; scutellum bluish green; elytra bluish green broadly along suture, with golden green dorsal longitudinal stripe, reaching from base to apex of elytra, cupreous golden sides from humeri to apex, and bluish epipleural margin.
Head large, transverse, strongly punctured, longitudinally furrowed from interantennal space to epistome; epistome short, straight, strongly punctured. Mandibles short, thick, slightly bent apically. Labrum trapezoidal, free, covered by fossulae and abundant golden setae. Eyes microfaceted, weakly protruding; upper lobe much smaller than lower. Antennae long, covered by long black setae and reaching apical 1/5 of elytra in males and apical quarter in females; segments saw-like beyond fifth antennomere, each segment (except first and second) with strong longitudinal outer margin demarcating two longitudinal porous areas.
Pronotum transverse (17:24), with strong transverse anterior depression on disc and two posterior transverse medially prominent humps; anterior border simple, posterior border weakly margined; sides armed with short median smooth bulge and smaller protuberance close to anterior angle; surface of pronotum strongly punctured, with golden setae at sides. Prosternum nearly smooth, shiny, with transverse striation at anterior half; prosternal process broad, punctured, expanded posteriorly to enclose procoxal cavities behind. Mesoventrite short, transverse, strongly punctured, wide between mesocoxae. Metaventrite longitudinally furrowed, finely punctured, covered by dense silvery white pubescence. Abdominal ventrites rather smooth and glossy, weakly punctured, sparsely pubescent; puncturation on pygidium stronger.
Scutellum triangular, margined laterally, smooth, depressed medially. Elytra long, narrow (11:4), sides subparallel; humeri round, protruding; suture fine, unmarginated; apex of elytra broadly round, with slightly marked sutural angle; surface of elytra rough, particularly at basal third, less so at apical quarter, covered by very sparse short, fine silvery tomentum; pubescence in apical area longer, denser and black.
Legs short and slender; profemora enlarged medially, meso- and metafemora widened apically; mesotibiae slightly arched, metatibiae flattened; pro- and mesotarsi short and wide; first metatarsomere laterally compressed, and remaining metatarsomeres short and broad.

The species is named after the type locality “Yunnan”.
China: Yunnan.
This species is very typical with sexual dimorphism represented by larger mandibles in males than females.

This is a very rare species only known from China, Myanmar and Vietnam. It is close to

This is a typical oriental species. Very common in Laos and Vietnam and should be common in South China too.
China (
This species is highly polymorphic in elytral and pronotal coloration. The IZAS collection contains specimens showing the base of elytra completely red, and the series from Yunnan includes specimens with their pronotum black and reddish.
