Operclipygus juninensis Caterino & Tishechkin 2013

This species is extremely similar to Operclipygus sejunctus, differing only in a few characters as follows: length: 1.44–1.75 mm, width: 1.28–1.34 mm; body uniformly rufo-piceous; frons depressed, with coarse punctures intermingled with fine ground punctation; supraorbital stria interrupted; pronotal disk with slightly broader band of lateral punctures; elytra with sutural stria frequently longer, present on apical two-thirds to three-fourths; coarser elytral punctures densest at apex, but with few coarse punctures extending up the apical thirds of interstriae (as they do in Operclipygus pecki); sterna quite variable, but generally similar to Operclipygus pecki, the mesoventral disk with few coarse punctures at sides; metaventral disk with strong ground punctation, with coarser punctures gradually becoming larger and denser toward metacoxae; secondary lateral metaventral stria longer, extending from mesometaventral suture about halfway to metacoxa; pygidia also as in Operclipygus pecki, with very dense punctation. Male genitalia (Fig. 20F): as in Operclipygus sejunctus except S9 shorter, more markedly expanded to base, with basal margin varied from truncate to broadly rounded, lacking apical emargination, lateral flanges wide and strongly recurved at inner corners; tegmen with sides more or less evenly rounded from base to apex, apex subacute, medioventral process short, wide, slightly sinuate, with strong apical point located just basad tegmen midpoint, projecting beneath; median lobe about one-fourth tegmen length.
