Diagnostic description.
This species is extremely similar to Operclipygus farctus , differing mainly in the following characters: length: 1.87-2.03 mm, width: 1.62-1.78 mm; body rufopiceous to faintly bicolored, with sides of elytra rufescent from dorsal stria 3 laterad, broad and subquadrate; base of pronotal disk strongly flattened to weakly plicate; anterior pronotal corners curved downward, nearly vertical at sides; elytra with outer subhumeral stria present in apical third, inner subhumeral stria absent, striae 1-3 complete, 4th stria present in apical fourth to one-half, 5th stria present in apical third, sutural stria present in apical two-thirds; meso- and metaventrites wide and short, mesoventral stria complete, mesometaventral stria broadly arched to middle of mesoventral disk; propygidium with punctures moderately small, round, separated by about their diameters; pygidium as in Operclipygus farctus . Male genitalia mostly similar to those of Operclipygus farctus (see Figs 48 A–D, K), except with ventrolateral apodemes of T8 more distant ventrally, midlateral desclerotization not distinct (though it is still notched as seen in lateral view); S9 more strongly and somewhat asymmetrically expanded basally.
Remarks.
Where bicolored (Fig. 47A), this species is easy to recognize, but nearly half of available specimens are uniformly colored. In those cases the body shape, in addition to the generally short 4th dorsal stria, will distinguish it from Operclipygus farctus . We restrict the type series to specimens from the Nova Friburgo vicinity, as these are the only ones that consistently show the rufescent elytral coloration.
Etymology.
The name of this species refers to the reddish coloration of the elytra.
