Operclipygus atlanticus Caterino & Tishechkin 2013

This species is very similar to the preceding, differing in a few characters as follows: length: 1.81–1.93 mm, width: 1.50–1.59 mm; body slightly less strongly convex; anterior submarginal pronotal stria more nearly straight across the front, not strongly arched into anterior corners; elytra with outer subhumeral stria present in apical half only, inner absent; propygidium with punctures more nearly round, sparser, separated by slightly more than their diameters; pygidium not strongly convex, with marginal sulcus obsolete in basal corners. Male: genitalia extremely similar to those of Operclipygus farctus (see Fig. 48A), except S8 (Fig. 48F) with apices of guides more strongly protuberant at inner angles; T9 (Fig. 48G) with bulbous basolateral angles; tegmen (Fig. 48M) slightly broader toward apex, more gently curved ventrad, not strongly bent.
