Derivation of Name. The specific epithet is the Spanish word for cloudy or gloomy, and refers to the cloud-forest habitats (‘‘bosques nublosos’’) of the species. It is used as a noun in apposition.

Diagnosis. The short antenna, and the narrowly rounded tip of the aedeagus in dorsal view distinguish the species.

Antenna short ( Fig. 12 View Figs ), not reaching base of pronotum when laid back; segments 4–10 shorter than wide, segment 7 nearly quadrate, 8 very transverse. Pronotum widest at base, with fine dense transverse striae. Elytra with fine dense oblique striae. Flight wings functional. Mesosternal carina present, of medium development in profile. Aedeagus small, curving to sharper tip in lateral view ( Fig. 13 View Figs ), tip in dorsal view narrower, rounded ( Fig. 14 View Figs ); internal sac (flagellum) broad and elongate at base, elongate, thin and straight at apex.
