Occiput mostly gray tomentose, shiny area dorsally bordered ventrally with yellow or brownish tomentum; white setose; stout yellowish or brownish-yellow bristles dorsally.

Thorax. Black, with bluish reflections dorsally; length greater than wide. Pronotum yellow tomentose. Scutum with short decumbent setae, anterior broadly, lateral and posterior margins narrowly yellow setose, medially setae blackish in lateral view, brownish or yellowish in dorsal view; lateral bristles yellow or brownish-yellow.

Abdomen: About twice as long as thorax, narrow, 5 times as long as segment 2. Ground color black with blue reflections; yellow setose, short setae dorsally mixed with black, setae much longer laterally, those on tergites 1–2 laterally whitish.

Distribution. Captured at low to high (20–1250) elevations during June and July from

Hato Mayor, Independencia, La Altagracia, and Pedernales provinces in the Dominican

Republic and Puerto Rico. Etymology. Latin sola referring to it being the only known species of the genus in Hispaniola and Puerto Rico.

Remarks. Cerotainia sola is similar to C. laticeps Bromley (1929) but differs in the yellowish tomentum of the head, blackish setae on the face and the scutum, yellowish setae of the head, thorax, and legs, black legs, brownish wings, narrow abdomen and terminalia ( Figs. 33–36). In C. laticeps the frons is silvery tomentose, the setae of the scutum is entirely brassy, the tibiae are brown with narrow apices black, the hyaline wing, and broad abdomen.
