This species is very similar in most characters to Operclipygus mirabilis and is only described to the extent that it differs from the above. Length: 1.62–1.93 mm, width: 1.37–1.65 mm; pronotum with well developed basal plicae; anterior submarginal pronotal stria present, recurved with ends divergent; anterior marginal stria complete or barely interrupted at middle; male with divergent, sublinear depression on each side laterad and parallel to divergent arm of anterior submarginal stria, these depressions bearing median pronotal gland openings near their posterior-most ends; lateral submarginal pronotal stria similarly complete in both sexes; elytron lacking inner subhumeral stria, sutural stria obsolete in basal third, not meeting basal arch of 5th stria; pygidium with marginal stria faintly impressed along apical third of margin, rarely obsolete. Male with apical guides of S8 slightly narrower apically than in Operclipygus mirabilis; aedeagus more strongly hooked at apex.
