OMOPHRON VIRENS ANDREWES, 1929

Description: lenght: 6 5 mm; width: 4 mm. Colour testaceous yellow, sterna and front margin of prothorax piceous; back and sides of head, a transverse patch on prothorax, extending to base and covering the central half, extending also to a broad point at middle of apex, and an elytral pattern rather bright green.

Head flat, front smooth, some vague striae near eyes, vertex and sides punctate, clypeus quadrisetose, a little emarginate and vaguely bordered in front, clypeal suture angulate, labrum slightly emarginate, mandibles short and very sharp at apex, mentum with rounded lobes, the epilobes not projecting, subocular ridge extending beyond buccal fissure, the area in front of it coarsely, though rather vaguely, striate-punctate.

Prothorax moderately convex, rather shiny, not or only very slightly coriaceous, strongly punctate along front and hind margins, disk nearly and sides quite smooth, sides only faintly rounded and base faintly sinuate near hind angles, median line short but distinct.

Elytra ovate, convex, base unbordered, sides moderately dilated behind shoulder; 15-punctate; striate, the punctures clearly marked and rather close together intervals moderately convex, equally wide throughout, each with a row of punctures so fine as to be visible only under a strong lens. A fine microsculpture is present. The elytral pattern is as presented in Fig. 2.1.

Comparisons: afar as pattern goes, the O. virens Andr. bears a strong likeness to O. lunatus Bänn. , but it will be readily distinguished by its green colour, more elongate form, quadrisetose clypeus, and nearly smooth elytral intervals

OMOPHRON YUNNANENSE TIAN & DEUVE, 2000

Description: lenght ~ 5.5 mm; width: ~ 3.8 mm. Colour testaceous, patterns on head, pronotum and elytra dark green; feebly shiny; the patch on pronotum wide, extending sides margin; base of elytra is green to stria 11, intervals 1-2 green to preapex; the front fascia reaching stria 11, very narrow on intervals 8-9, mid fascia extending to stria 12, hind fascia only reaching stria 10.

Head moderately convex, clypeus bisetose, smooth, strongly transverse, front margin hardly bordered, slightly emarginate, and with the median membraneous base of labrum visible; clypeal sulcus very fine, almost arcuated underside of head rugose, without punctures in central area, but punctate at sides, subocular ridge nearly straight, coarsely punctate in front, glabrous in hind, rugose; tooth of mentum distinct.

Pronotum strongly transverse, moderately convex, coarsely punctate; widest at base, with fairly wide, smooth reflexed margins; sides almost straight, slightly contracted just before hind angles, hind angles subrectangular; median line feeble; base margin obliquely bisinuate; a weak break in the contour at the junction of pronotum and elytra.

Elytra convex, bordered at base, striae rather shallow, moderately and uniformly punctate, intervals smooth. Protarsi of male with joint 1 a little expanded, as long as joints 2 + 3; prosternum well bordered laterally and with moderately sparsely punctate; mesosternum rather longer, flat, glabrous; metasternum punctate; metacoxae bisetose, sternites 5-7 bisetose.

Comparisons: Among other species this species stands out because of the extended green spot on the pronotum, well marked mesisternum, peculiar pattern on the elytra and the form of aedeagus.
