Diagnosis.

Head broad, with lateral vertexal foveae deep, not setose, closer to eyes on each side than to each other; eyes protuberant but not large, diameter ~ 2 / 3 postocular genal length; pair of gular fovea present; antennae short, antennomere III slightly longer than wide, antennomeres IV – VI beadlike, rounded, VII – IX increasingly transverse, shorter, antennomere X ~ 2 × the size of antennomere IX, transverse, acuminate anteriorly, XI ~ 3 × as long as X, rounded; male pronotum (Fig. 4 D View Figure 4 ) wider than long, widest at base, evenly narrowed to front; posteromedial portion of disk with deep pair of well-defined, slightly elongate depressions; each posterolateral corner of pronotal disk with shallower depression; prosternum with pair anterior prosternal foveae present; first visible tergite ~ 2 × length of 2 nd or 3 rd, with close pair of abbreviated longitudinal carinae; each elytron with four basal fovea, three foveae evenly spaced and one distant; legs simple, mesotrochanter slightly toothed in the mid-section; flight wings present. Aedeagus (Fig. 6 D View Figure 6 ) elongate, with separate accessory sclerites; parameres separate, knobbed at base, contacting and articulating with side of median lobe at basal third, thence free distally, with apical setae; median lobe with small, round basal foramen; tegmen rather flat, widest at base and apex, narrower over middle 1 / 2; apex of tegmen asymmetrical, apical margin deeply emarginate on one side, obliquely rounded on other, with converging strengthening thickenings converting to tip; accessory sclerite almost symmetrical, with thick, sclerotized basal arch deeply separated from flatter, distal portion forming an elongate blade bearing a distal style. TL 1.64 mm, EW 0.49 mm.

Distribution.

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

Etymology.

The name of the species refers to the fact that several Panabachia species live ‘ amicably’ together at this locality.

Remarks.

This species follows several with very similar male genitalia, differing markedly, however, in pronotal shape. In this species the pronotum (Fig. 4 D View Figure 4 ) is widest at the base, with large median and smaller lateral basal depressions, very different from most of these that have any pronotal modifications anterior or absent.
