Diagnosis.

Head broad, subquadrate, with lateral vertexal foveae deep, non-setose, median fovea absent; eyes protuberant, small, diameter ~ 2 / 3 of the postocular genal length; two gular fovea present; antennal bases slightly elevated, set off by striae, antennae short, antennomere III slightly longer than wide, antennomere IV – VI beadlike, rounded, VII – IX increasingly transverse, shorter, antennomere IX transverse, 2 × the size of antennomere VIII, antennomere X transverse, apically truncate, 2 × the size of antennomere IX, antennomere XI ~ 2 × as long as X, setose, rounded, no antennal differences between male and female; male pronotum (Fig. 4 C View Figure 4 ) simple without secondary sexual modifications, slightly wider than long, widest toward front, with very fine median fovea near base; prosternum with two anterior prosternal foveae present; wings present; each elytron with four basal foveae, evenly spaced; male last sternite (Fig. 5 K, L View Figure 5 ) transverse, setose, with a forked process along the inner basal margin, apical margin sinuous, with denser setae at middle; male apical tergite transverse, apically truncate, setose along posterior margin, slightly emarginate in the middle; legs simple. Aedeagus (Fig. 6 C View Figure 6 ) elongate, with separate accessory sclerites; parameres separate, thin at base, converging and fused with median lobe basad of middle; median lobe with small, obovate basal foramen; tegmen rather flat, widest basad middle, constricted, then expanded, apex asymmetrical, apical margin deeply emarginate on one side, mostly outwardly convex on the other, with bluntly produced tip between; each accessory sclerite with thick, sclerotized basal arch, with subrectangular basal part deeply separated from flatter, distal portion forming an elongate blade bearing a distal style. TL 1.53–1.71 mm, EW 0.40–0.43 mm.

Distribution.

This species is only known from grassland and shrub páramo from Mt. Mojanda, province of Imbabura, Ecuador.

Etymology.

The species is named in recognition of the unmodified male pronotum.

Remarks.

Despite a close relationship to the preceding and especially following species on the basis of male genitalic morphology, this species is amply distinguished by its unmodified male pronotum (Fig. 4 C View Figure 4 ).
