 This species is extremely similar to Operclipygus intermissus and Operclipygus variabilis, differing mainly in the following characters: length: 1.53–1.62 mm, width: 1.28–1.30 mm; frons always with central portion of frontal stria present, detached from sides; pronotal disk with fragments of lateral submarginal stria usually present in anterior corners; anterior stria recurved, usually complete, though rarely interrupted at median pronotal gland opening (as seen in holotype); elytra with 4th stria abbreviated basally, present in anterior one-half to two-thirds; pygidium rather wide and short, with the marginal sulcus comprising large, deep punctures, ground punctation as in Operclipygus variabilis. Male genitalia (Figs 32D–G) as for group description, with the apices of S8 vertically oriented, curved to ventral apex, bearing 4 or 5 long apical setae, with very short submarginal sclerotization along upper, apical margins; T9 with apices obliquely subquadrate, widened to inner apical edges; T10 not divided; S9 narrow, with base only slightly widened, truncate, with shallow apical emargination; tegmen with sides straight, expanded toward broadly rounded apex.
