Operclipygus nitidus Caterino & Tishechkin 2013

This species is extremely similar to the preceding, Operclipygus pacificus, differing only in the following characters: length: 2.12–2.56 mm, width: 1.87–2.28 mm; frons more strongly depressed, with central portion of frontal stria present as small median arc; submarginal pronotal stria obsolete in basal half of lateral margin; elytra nearly always with short apical marginal stria or apical series of punctures; prosternum narrower, with carinal striae more clearly convergent anteriorly; 1st abdominal ventrite with single lateral stria ending in small but distinct fovea behind inner corner of metacoxa, rarely continuing laterad behind coxa for short distance; pygidium with small punctures uniformly interspersed with fine, dense ground punctation. Male genitalia more or less indistinguishable from that of Operclipygus pacificus (see Figs 77A, C, H), except with S9 (Fig. 77F) more clearly desclerotized along midline, widened basally, with distinct, narrow basal emargination; tegmen widest just basad middle, weakly narrowing to apex, slightly thicker dorsoventrally; basal piece short, about one-fourth tegmen length.
