Diagnosis.

Body (Fig. 3 E View Figure 3 ) dark reddish, densely covered with short, semierect setae; head broad, subquadrate, densely setose, with lateral vertexal foveae deep, not setose, closer to eyes on each side than to each other; eyes protuberant but not large, diameter slightly greater than postocular genal width; genal carinae not exaggerated; two gular foveae present; antennal bases slightly elevated, set off by oblique stria; antennae short, antennomere I short, cylindrical, II similar in width, ovoid, III – VI, beadlike, rounded, VII – IX increasingly transverse, shorter, X short, XI ~ 2.5 × as long as X, narrowly rounded, densely setose, with depression on inner apex; no pronotal dimorphism, pronotum (Fig. 4 K View Figure 4 ) slightly wider than long, widest near middle, slightly constricted before the base; median pronotal fovea fine, deeply impressed; each elytron with four basal foveae, evenly spaced; sutural stria complete, discal stria absent; wings absent; 1 st abdominal tergite with close, short pair of curved basal carinae; pair of anteroprosternal foveae present; legs simple; 1 st male abdominal ventrite (Fig. 5 E View Figure 5 ) weakly emarginate at middle; last male ventrite wide, flattened, densely setose along most of apical 1 / 2; last male tergite with apical margin wide, setose, similar to opposing ventrite. Aedeagus (Fig. 6 J View Figure 6 ) relatively flat, with basally free parameres and separate accessory sclerites; parameres fused to median lobe at sides of large, elongate oval basal foramen; median lobe with enlarged basal knob, distally widening slightly to asymmetrically bifid apex, with left side emarginate; accessory sclerites slightly asymmetrical, with tightly coiled basal part, and enlarging, laminate distal part with curved and thickened margins. TL 1.38–1.60 mm, EW 0.35–0.41 mm.

Distribution.

This species is known only from páramo habitats at Cerro Atacazo, province of Pichincha, Ecuador.

Etymology.

This species is named for its proximity to the Quito metropolitan area.

Remarks.

This species is sympatric with P. patera , but distinctive in numerous characters. Panabachia urbana lacks male pronotal dimorphisms (Fig. 4 K View Figure 4 ) (and males can be easily recognized by modifications of the last abdominal ventrite; Fig. 5 E View Figure 5 ), and is also lighter in coloration, a bronzy brown, and broader in shape.
