Diagnosis.

Head (Fig. 3 D View Figure 3 ) broad, sparsely setose, with vertexal foveae deep, non-setose, closer to eyes on each side than to each other; 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 IX, transverse, bluntly acuminate, with setose depression on anterior surface, XI ~ 2 × as long as X, rounded densely setose with depression on inner apex; male pronotum (Fig. 4 J View Figure 4 ) almost as long as wide, sparsely and finely punctate and setose, setae slightly denser in anterior 1 / 3, widest behind midline, narrower at apex than base, anterior margin slightly rounded; posterior 1 / 2 of disk evenly convex, with fine median fovea; bifid depression (broad depression slightly constricted along midline) present in anterior third, anterior edge a little more abrupt than posterior; shallower, slightly oblique lateral impressions present alongside median ones; two anteroprosternal fovea present; each elytron with four basal foveae, evenly spaced; elytra sparsely setose, discal stria absent, apical stria incomplete; wings present, male last sternite flattened, transverse, sparsely setose; male apical tergite transverse, slightly convex in the middle, sparsely setose; legs simple. Aedeagus (Fig. 6 I View Figure 6 ) flat, with separate accessory sclerites; parameres separate, thin at base, briefly fused to median lobe subbasally, then free to apex, expanded; median lobe with basal apodeme distinct, T-shaped; basal foramen small, ovate; median lobe slightly narrowed beyond foramen, then expanded widely to weakly rounded, brushy apex, with setose apices of parameres alongside; accessory sclerites complex, asymmetrical, associated with base of median lobe rather than apex; both with tightly coiled base opening into elongate, sinuate distal processes, one much longer and thinner than other. TL 1.31–1.82 mm, EW 0.37–1.41 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 refers to the ‘ uneven’ anterior portion of the male pronotal disk.

Remarks.

This species is sympatric with P. uktu , and the two exhibit similar male genitalia (Fig. 6 H View Figure 6 vs Fig. 6 I View Figure 6 ). Yet there are clear differences in the more basally simpler median lobe of P. salebrosa , in its flatter median lobe, and in its more prolonged left accessory sclerite, as well as in minor differences of male pronotal morphology.
