Description

 This species is extremely similar to the preceding, differing significantly only in the following characters: length: 1.78–2.22 mm, width: 1.47–1.87 mm; frontal stria usually present at middle, interrupted only over antennal bases; labrum broader and more distinctly emarginate; marginal pronotal stria not descending onto hypomeron; lateral submarginal pronotal stria obsolete along most of lateral margin, present only in anterior corners; anterior submarginal stria broadly arched across anterior margin, recurved posterad one-fifth to one-fourth pronotal length; prosternum and mesoventrite not as distinctly depressed, posterior half of metaventrite only weakly convex; propygidium with vestigial fragments of microsculpture; pygidium lacking microsculpture, with relatively conspiuous fine ground punctation and coarser punctures rather dense in basal corners, smaller and sparser toward apex; marginal pygidial stria fine, present on apical half to two-thirds of margin. Male genitalia very similar to those of Operclipygus hamistrius (see Figs 57A–D), differing as follows: T8 with sides subparallel; S8 shorter, with apices bluntly subacuminate, ventral creases conspicuous; tegmen shorter, widest distinctly basad middle, with sides rounded, not as strongly narrowed to apex; tegmen like that of Operclipygus arquus (see Fig. 57K).
