Operclipygus confluens Caterino & Tishechkin 2013

This species is very similar to the preceding, differing as follows: length: 1.68–1.97 mm, width: 1.37–1.62 mm; body larger, broader; 5th and sutural elytral striae slightly longer and more broadly impressed; elytral striae 3-5 expanded at apex, striae 4-5 usually joined in apical arch; mesoventrite less deeply emarginate at middle; lateral metaventral stria extended more posteriorly; lateral striae of 1st abdominal ventrite closer to each other, subparallel; pygidial disk with coarser punctures sparser though slightly larger at middle; marginal pygidial sulcus deeper and coarser. Male: basal genitalic segments identical to those of Operclipygus diffluens (see Figs 40A–D); tegmen (Fig. 40J) shorter, sides subparallel in basal three-fourths, rounded to wider apex; basal piece shorter, less than one-third tegmen length.
