Operclipygus farctissimus Caterino & Tishechkin 2013

As with the preceding, this species is very similar to Operclipygus distinctus, except as follows: length: 2.03 mm, width: 1.87 mm; body piceous with elytra faintly rufopiceous; frontal stria very nearly complete, only narrowly interrupted above antennal bases; antennal bossae weakly produced; pronotal disk with strong basal plicae, extending forward about one-third pronotal length; central part of anterior pronotal margin very weakly projecting at middle; elytral striae not very strongly impressed, but striae 1-5 widened slightly to apex, outer subhumeral stria present in apical half only, inner subhumeral stria absent, striae 1-3 complete, 4th stria present in apical third, 5th stria present in apical fourth, sutural stria present in apical two-thirds; prosternal keel very broad, emarginate at base, carinal striae strongly divergent basally; mesoventrite weakly projecting, marginal stria interrupted; mesometaventral stria arched forward at middle, sinuate near mesocoxa, extending posterad toward inner third of metacoxa; propygidium with rather small, round punctures separated by about their diameters, finer ground punctures most evident toward sides and posterior margin; pygidium with fine, dense ground punctation, and few slightly coarser punctures near basal margin; marginal pygidial sulcus fine, obsolete in basal half. Male genitalia mostly similar to those of Operclipygus farctus (see Figs 48A–D, K), except that the ventrolateral apodemes of T8 are more distant ventrally, with midlateral desclerotization not distinct (though it is still notched as seen in lateral view); S9 more strongly and somewhat asymmetrically expanded basally, indistinguishable from that of Operclipygus subrufus.
