Diagnosis.

Head broad, sparsely setose, with lateral vertexal foveae deep, not setose, closer to eyes on each side; median fovea absent; eyes protuberant but not large, diameter ~ 2 / 3 of postocular genal width; two gular foveae present; antennal bases elevated, set off by oblique stria; antennae short, antennomere III slightly longer than wide, IV – VI beadlike, rounded, VII – IX increasingly transverse, X 2 × the length of antennomere IX, transverse, XI ~ 2 × as long as X, rounded, densely setose, with depression on inner apex; male pronotum (Fig. 4 I View Figure 4 ) approx. as long as wide, sides just slightly wider in anterior 1 / 2, weakly constricted basally; disk weakly depressed along basal margin, posterior 2 / 3 almost evenly convex, with fine mediobasal fovea; most of disk sparsely and finely punctate, with long, slightly flattened setae in punctures; small, oval median depression present just behind anterior margin, with interior circular carina within, setose within this circle and along upper margin of depression; oblique lateral depressions present extending posterolaterad from median depression, these with denser series of setae along anterior and lateral edges; two anteroprosternal foveae present; each elytron with four basal foveae, three foveae evenly spaced and one disjunct, discal stria absent; apical elytral stria incomplete; wings present; male last sternite (Fig. 5 B View Figure 5 ) flattened, setose along apical margin, with small bifid process on apical margin (this is the external manifestation of a larger, internal, forked lever that articulates outward when genitalia are everted), flanked by modified setae; legs simple. Aedeagus (Fig. 6 H View Figure 6 ) with base curved ventrad, flattening out and widened apically, with separate accessory sclerites; parameres long, connected at sides of basal foramen, free to setose apex; median lobe with basal apodeme curved underneath and slightly distad; basal foramen ovate; median lobe slightly narrowed beyond foramen, then expanded widely to subtruncate, brushy apex, with pads beneath; accessory sclerites complex, asymmetrical, associated with base of median lobe rather than apex; left side with short clubbed process at base, and long thin, apically curving distal process; right side with strong basal arch dividing into two thin, curved distal processes, neither as long as thin process of other side. TL 1.34–1.69 mm, EW 0.32–0.47 mm.

Distribution.

This species is only known from grassland and shrub páramo around the Atillo lakes, province of Chimborazo, Ecuador.

Etymology.

The name of this species comes from a Kichwa word meaning hole, referring to the male pronotal modification.
