A review of genus Omophron Latreille, 1802 (Coleoptera: Carabidae) Palearctic fauna and distribution Author Valainis, Uldis text Baltic Journal of Coleopterology 2010 10 2 105 128 journal article 10.5281/zenodo.13204399 1407-8619 13204399 OMOPHRON CHELYS ANDREWES, 1921 Description: lenght: ~ 4 mm , width: ~ 2.7 mm . Colour very dark metallic green, shiny; sterna piceous, clypeus, middle of front, and venter (except last segment) brown; labrum, palpi, antennae, side margin of prothorax, a pattern on elytra, and legs testaceous. Head moderately punctate at sides and back, front nearly smooth, clypeus smooth, bisetose, suture very fine, forming; an obtuse angle in middle, mentum with a rounded tooth, epilobes projecting, subocular ridge extending beyond fissure, coarsely punctate in front, impunctate behind. Prothorax transverse, convex, moderately and nearly uniformly punctate, base bisinuate on each side, sides gently and evenly rounded, with a smooth, explanate margin, slightly reflexed, median line obsolete. Elytra oval, convex, base unbordered, sides slightly widened behind shoulders, with reflexed margin narrower than that of prothorax; 15-striate-punctate, striae evanescent towards apex; intervals flat and smooth. No microsculpture. The elytral pattern is as presented in Fig. 1.6 . Comparisons: O. chelys Andr. is similar to O. brettinghame Andr., which is distributed in the Oriental region . In comparison with this species O. chelys Andr. has a little bigger and more prolonged body form, coarser punctation on its head, pronotum and elytral striae.

Colour moderately bright metallic green, shiny; sterna piceous, venter rather lighter; clypeus and labrum dark red; palpi, antennae, middle of front, side margins of prothorax and elytra, and legs testaceous. Head moderately punctate, more sparsely on middle of front, clypeus smooth, bisetose, suture very fine, almost arcuate, mentum with rounded lobes, epilobes forming a sharp point at extremities, subocular ridge extending beyond fissure, coarsely punctate in front, impunctate behind. Prothorax moderately punctate, rather sparsely on disk, base bisinuate on each side, sides evenly rounded, with smooth, slightly re- flexed margin, median line nearly obsolete. Elytra oval, con-vex, base unbordered, sides slightly widened behind shoulder, with narrow reflexed margin; 15-striate-punctate intervals flat and smooth. No microsculpture. The elytral pattern is as presented in Fig. 2.2 . Comparisons: O. gemmeum Andr. is similar to O. brettinghame Pasc., which is widespread in the Oriental region . In comparison with the species O. brettinghamae Pasc. , the side margins of pronotum and elytra of O. gemmeum Andr. do not merge into one line. The side margins of pronotum and elytra of O. gemmeum are narrower; the pronotum punctation is coarser. O. gemmeum has a visible middle segment of the elytra pattern, but in the case of O. brettinghamae it is almost reduced.

Colour testaceous, dull, front of head pale yellow, sterna piceous, ventral side, patch of pronotum, patches on back and side of head, central pronotum and elytra dark green. Head with narrower green patch along base, only extending to the half of eyes, front margin arcuate backward at sides. Pronotum hardly depressed along base, moderately and irregularly punctate, but not so at sides. Sides very slightly rounded, faintly constricted near hind angles, which are nearly rectangular but rather blunt. Patch on pronotum ocuppying only the central half, attacking base, apical pointed but not extending frontal margin. Elytra oval, strongly convex, base unbordered, sides distinctly but not strongly dilated behind shoulders; 15-punctate-striate, punctures moderate; intervals rather flat, not convex at sides, smooth, with isodiametric microsculpture.

Color flavous, beneath testaceous, an ill-defined transverse patch on middle of prothorax light brown; a narrow border at back of head and along internal margin of eye, a very small central basal patch on prothorax, and an elytral pattern very dark green. Head flat, smooth, faintly striate near eyes, clypeus smooth, bisetose, widely emarginate in front, suture with an obtuse angle in middle, labrum emarginate, mentum small, deeply emarginate, lobes rounded, tooth acute, subocular ridge visible only as a short furrow behind buccal fissure, area behind eye lightly striate-punctate. Prothorax coriaceous, moderately convex, base bisinuate, sides almost straight, hind angles not much rounded, median line distinct, the dark colour at base extending along it to apex. Elytra short oval, moderately convex, base with an ill-defined border at sides, sides not much dilated behind shoulder, border minutely and incon-spicuously dentate in front; 15-punctate-striate, intervals, flat and smooth on disk, convex, narrower, and slightly rugose at sides. A fine microsculpture is present. The elytral pattern is as presented in Fig. 2.4 .
