Diagnosis: Male. Length (1.50–1.81 mm). Width (1.00– 1.31 mm). Subovate, cuticle orange, legs, antenna and apex of rostrum yellow. Vestiture of ochreous to brown scales, recumbent and appressed, mesanepisternum and mesepimeron bearing appressed scales. Rostrum, antenna and scrobes as in P. velizi . Pronotum oval, transverse, annulate anteriorly, punctate, three dorsal vittae of ochreous scales, other scales brown, postocular lobes, postocular lobe with vibrissae. Elytral with humeri produced, in some males enlarged as wing-like shape, tubercles several within base of elytra to base of elytral declivity, two subconical tubercles at base of elytral declivity, punctate-striate, punctures deep, slightly compressed laterally. Abdominal ventrites punctate, punctures with setae, abdominal ventrite 2 as large as abdominal ventrites 3 and 4, ventrite 5 without tufts of setae or at least not evident, apex rounded. Metanepisternal suture swollen. Femora unarmed, tibiae uncinate, pro– and mesocoxae with plumose scales. Pedon subparallel, moderately curved in lateral view; temones 3.1X longer than pedon; anterior genital sclerite short, strong, with two anterior claw like projections, posterior genital sclerite flagellate.

Female. Length (1.75–2.06 mm). Width (1.00– 1.25 mm). As for the male except humeri sharply pointed but not wing-like, rostral scales only at base not reaching antennal insertions, tubercles smaller.

Geographic Distribution. Costa Rica (Heredia, Monteverde and Puntarenas).

Derivation of the specific name. Patronym, named after Angel Solís, a scarabaeidologist at the National Museum of Costa Rica.
