Diagnosis.

Head (Fig. 3 G View Figure 3 ) broad, densely setose, with lateral vertexal foveae deep, setose, closer to eyes on each side than to each other, median fovea absent, eyes protuberant but not large, diameter approx. equal to postocular genal width; two gular foveae present; antennal bases elevated, set off by oblique stria; antennae short, antennomere III slightly longer than wide, antennomere IV – VI beadlike, rounded, VII – X increasingly transverse, shorter, antennomere XI short, ~ 2 × as long as X, rounded, densely setose, with depression on inner apex; no antennal differences between male and female; male pronotum (Fig. 7 E View Figure 7 ) narrow, elongate, subrectangular, basal 2 / 3 widest, sides slightly rounded, then weakly constricted, with anterior portions of lateral margins widened slightly to front; anterior pronotal margin outwardly arcuate; posterior portion of pronotal disk with broad circular depression, lacking setae within but with small basomedial fovea, setose along lateral margins and with pair of inwardly directed setal tufts at anteromedial edge; anterior portion of pronotal disk with pair of small impressions at middle and pair of slightly larger impressions at sides; two anteroprosternal foveae present; each elytron with four basal foveae, lateral foveae evenly spaced, discal stria absent; wings present; last male sternite (Fig. 5 D View Figure 5 ) convex, male apical tergite transverse, slightly depressed in the middle, legs simple. Aedeagus (Fig. 8 F View Figure 8 ) with elongate median lobe and separate accessory sclerites; parameres not evident; median lobe with narrow, ventrally bent basal apodeme and large elongate oval basal foramen, apical 1 / 2 narrow, curved to acute apex; accessory sclerites compact, with sclerotized basal knob articulated with elongate, somewhat bean-shaped apical portion, its apex distinctly hooked. TL 1.46–1.57 mm, EW 0.36–0.39 mm.

Distribution.

This species is known only from páramo habitats on Cerro Atacazo, just southwest of Quito, in Pichincha province, Ecuador.

Etymology.

This species’ name, derived from the Latin, refers to its ‘ bowl-shaped’ male pronotal modifications.

Remarks.

This species is sympatric with Panabachia urbana . The males are easily separated by the fact that this species has strong pronotal dimorphism, being elongate, subquadrate, and deeply foveate (Fig. 7 E View Figure 7 ), while in P. urbana the males’ pronota are not modified. Both may be recognized as males by the broad and setose last abdominal tergite and ventrite (Fig. 5 D View Figure 5 ). Females of P. urbana have not been identified. But we would expect its females to be broader, especially the pronotum, and lighter.
