Mesotibiae and metatibiae with medial transverse carina, carina with 6–8 spine-like setae; apex semicircular, transversely truncate. Genitalia: as in ( Fig. 22 ).

Variation. Five male paratypes do not differ significantly from holotype; length ranges from 7.81–8.52 mm, width 2.85–3.51 mm. Two specimens have elytra that are lighter in color than holotype. One specimen has 9 elytral striae.

Distribution. The species is known from Villa de Leyva and Iguaqué (Boyacá, Colombia).

Locality records \ (6 adults, 5 males and 1 female). Colombia: Boyacá, Municipio de Villa de Leyva. Boyacá, Municipio de Villa de Leyva, Santuario de Flora y Fauna de Iguaque ( Fig. 29 ).

Temporal distribution. October, November.

Diagnosis. Males of this species are most easily recognized by the following combination of characters: clypeus rounded; antennal club with 5 antennomeres, elytra with 8 striae. The unique form of the parameres is also diagnostic.

Etymology. From the latin “ penta -” and “- phylla ”, referring to the five antennomeres on the antennal club of this species.

Natural history. Specimens of E. pentaphylla have been attracted to lights in a dry forest ( Fig. 27 ) in the Andes at elevations between 2,100–2,800 m.
