description: <b> <i>Apodrosus epipolevatus</i> Girón &amp; Franz sp.n.</b> (Fig. 9) <i>Diagnosis</i> <i>Apodrosus epipolevatus</i> is characterized by the combination of subplane to convex dorsal outline in lateral view, an indistinct nasal plate, a slightly tuberculate surface of the elytra, an alternating color pattern of scale vestiture on the legs, a strongly produced surface of the elytra basad of the midpoint of interval X, a complete separation of elytral striae IX and X along their entire length, and a vestiture composed of brown and light brown to white, iridescent (greenish, yellowish to reddish) scales, and with recurvate, semi-erect setae.

There is also slight variation in the degree of projection of the elytral elevations. <i>Etymology</i> Noun in apposition. Named after the Greek <i>epipole</i> signifying “surface” and the Latin <i>levatus</i> signifying “raise” (Brown 1956), thus referring to the characteristic elytral elevations of this species. <i>Natural history</i> <i>Apodrosus epipolevatus</i> occurs at some of the highest elevations of the Puerto Rico Central Cordillera (Cerro de Punta, Monte Jayuya, Carite) (Fig. 19A). Under laboratory conditions the oviposition pattern corresponds to “type a” according to Emden (1950; cited by Marvaldi 1999), in which the eggs are laid separately and randomly; the egg shell is white when recently oviposited, becoming darker during subsequent days. The observed eggs hatched within 14-16 days. Only first instar larvae were obtained at that time. The host plant associations remain unknown.
