Operclipygus subviridis Caterino & Tishechkin 2013

Length: 2.06–2.56 mm, width: 1.81–2.31 mm; body rufobrunneus, generally with a very faint, dull greenish tinge, elongate oval, strongly convex; frons depressed at middle; frontal stria rounded at sides, broadly interrupted above antennal bases, with a short sinuate fragment at middle; supraorbital stria weak, detached from sides of frontal stria; labrum narrow, less than twice as wide as long, weakly emarginate at apex; left mandible untoothed, right with small, subacute basal tooth; pronotal disk weakly depressed basomedially, but lacking distinct prescutellar impression, with very fine, inconspicuous ground punctation and ~10 larger, shallow punctures at sides; marginal pronotal stria interrupted behind head; submarginal pronotal stria continuous across front and along anterior half of lateral margin, obsolete basally; elytron with two complete epipleural striae, outer subhumeral stria absent or represented as very short fragment in apical half, inner subhumeral stria absent, striae 1-2 complete, 3rd stria present in basal third, and as short apical fragment, striae 4-5 represented by short apical fragments only, sutural stria present in apical three-fourths; elytral disk with crenulate, frequently fragmented apical marginal stria; prosternal keel broad, truncate at base, carinal striae converging almost straight to narrow anterior arch; meso- and metaventrite together convex; mesoventrite short, wide, not projecting anteriorly, marginal stria broadly interrupted; mesometaventral stria broadly arched forward to near mesoventral margin; lateral metaventral stria short, not extending past middle of ventrite; 1st abdominal ventrite with single, abbreviated lateral stria, with small fovea behind inner corner of metacoxa; propygidium and pygidium with dense, fine, shallow ground punctation; propygidium with coarse basomedial punctures, sparser laterally and posteriorly; pygidium with few very small, interspersed coarse punctures; apical marginal stria absent. Male genitalia (Figs 77B, D, G, I): accessory sclerites absent; T8 short, sides subparallel in basal two-thirds, convergent to apex, apical emargination narrow, basal emargination deep, broad, nearly reaching basal membrane attachment line, ventrolateral apodemes separated beneath; S9 with sides subparallel to weakly convergent with narrowly rounded apices, ventral halves approximate at base, diverging weakly to apex; T9 subparallel in basal two-thirds, apices narrow; T10 with halves separate; S9 strongly narrowed at middle, with sides subparallel in basal fourth, base narrowly subtruncate, apex with very narrow median emargination, apical flanges interrupted; tegmen widest near base, very gradually narrowed to apex, with little dorsoventral curvature, medioventral process visible from above as a narrow ‘V’-shaped sclerotization, mostly contained in ventral membrane, very weakly projecting beneath; median lobe about half tegmen length, very thin; basal piece about one-third tegmen length.
