Diagnosis.

Head broad, subquadrate, with two vertexal fovea, deep, not setose, closer to eyes on each side than to each other; eyes protuberant but not large, diameter ~ 1 / 2 post-ocular genal length; antennal bases slightly elevated, set off by striae; antennae short, antennomere III slightly longer than wide, antennomeres IV – VI weakly transverse, VII – IX increasingly transverse, shorter, antennomeres IX – XI forming loose club, IX and X slightly shorter along inner margins, X 2 × as long as IX, transverse, XI ~ 3 × as long as X; male pronotum (Fig. 4 B View Figure 4 ) approx. as long as wide, sides almost evenly rounded, widest at middle, evenly depressed along basal margin; anteromedian portion of disk with large cordate depression, with additional, large anterolateral depressions in each corner; anterior marginal portion of pronotal disk transversely convex, with distinct posterior margin overlapping median and lateral depressions, this swelling relatively densely punctate and setose, with row of particularly elongate setae at lateral corners, two anteroprosternal foveae; each elytron with four basal foveae, three foveae evenly spaced and one more distant; legs simple; last abdominal ventrites missing (lost during extraction). Aedeagus (Fig. 6 B 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, ovate basal foramen, narrowed toward apex, distal portion dorsoventrally flattened, asymmetrical, apical margin obliquely subtruncate on one side, emarginate on the other; each accessory sclerite with thick, sclerotized basal arch, with a thin, distal portion forming a laminate, elongate semicircle with distal style. TL 1.58 mm, EW 0.47 mm.

Distribution.

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

Etymology.

The species is named for its tripartite pronotal depressions.

Remarks.

As discussed above, this species is similar in male genitalia (and presumably closely related) to the preceding and two following. However, it is readily identified by external characters, with the three anterior pronotal depressions (Fig. 4 B View Figure 4 ) and the unique punctate / setose anterior marginal band in front of them.
