Smaragdina quadrimaculata Lopatin , new species

( Figs 1, 2 )

Holotype male, China, Yunnan, env. of Lijang, Tiger Leaping Gorge , 2000 m, N 27°04'53" E 100°04'31", 25.05.2002, A. Konstantinov & M. Volkovitsh leg. ( IZAS) . Paratype female, the same label as holotype ( USNM) .

Body length 3.0 mm, width 1.5 mm. Body color orange-yellowish, vertex, two spots on each elytron (at basal one third and posterior of middle), metasternum and abdomen black with metallic luster. Three basal antennomeres orange-yellow, rest of antennomeres reddish-brown. Legs orange-yellow, only claw brown.

Frons convex with small impression in middle, covered with small dense punctures. Antennomere three very small, round, much shorter than either two and four. Antennomere four ax-shaped. Antennomeres five to nine wider than long, ten slightly narrower than nine, 11 elliptical with acute apex.

Pronotum twice as wide as long, convex, smooth, with widely rounded posterior corners. Basal margin widely protruding above scutellum.

Elytra 4.7 times as long as pronotum and 1.4 times longer than wide, slightly constricted posterior of humeral callus, widening posteriorly. Elytral apex narrowly rounded. Elytral punctures distinct, relatively deep basally, shallower apically, in some places forming irregular striae.

Ventral side of body with tiny and dense punctures. Abdomen with thin, white, appressed hairs, denser at sides. Aedeagus as in Figs1 and 2 .

Comments: Smaragdina quadrimaculata is similar to S. nigrosignatus Pic from Fuxian but can easily be differentiated by the color pattern of elytra and the shape of the aedeagus.

Etymology: This species name refers to its body color and the pattern of the elytra.
