Pronotum (Figs. 1, 3): convex, wider than long at middle. Surface densely punctate, punctures ocellate, setose, moderate in size (0.038–0.046 mm). Marginal bead present; anterior margin concave; lateral margins slightly angulate, setose, setae hair-like, long; posterior margin slightly defined at middle. Anterior angles rounded; posterior angles broadly rounded. Scutellum (Fig. 1): surface opaque, densely punctate, setose; punctures ocellate, moderate in size (0.016–0.020 mm), scutellar apex rounded. Elytra (Fig. 1): Convex, elongate, subparallel. Surface opaque, densely punctate, setose; punctures moderate in size (0.03–0.05 mm); setae long, hair like. Elytra with 8 striae. Elytral margins setose, setae long, hair-like. Hind wings (Fig. 8): subcostal and radial vein well sclerotized, not reaching radial sector vein at wing apex; radial sector vein forked at apex; medial vein well developed; medial loop short; cubital vein slightly sclerotized apically from medial loop connection; anal veins 1, 2 not connected, not forming a basal cell. Venter: prosternal process absent, on the side slightly concave, surface densely setose; setae slender short, tawny. Mesosternal surface sparsely setose, slightly concave at middle. Metasternal surface densely punctate, punctures ocellate, setose; setae slender and long; metasternal apex divergent. Propygidium slightly convex at middle. Pygidium: recumbent, surface densely punctate, punctures ocellate; with moderately long, slender setae. Legs (Figs. 10–12): coxae sparsely setose, setae long.

Elytra (Fig. 2): convex, elongate. Surface shiny, densely punctate, setose; punctures moderate in size (0.066–0.100 mm); setae long, hair like. Elytra with 8 striae. Elytral margins setose, setae long, hair-like. Venter: surface setose, setae moderately dense, slender, short, tawny. Metasternal surface sparsely setose, punctate; punctures moderately dense, ocellate, setose; setae slender, long; metasternal apex divergent in middle. Pygidium: not recumbent; surface densely punctate; punctures ocellate, setose; setae slender, moderately long. Legs (Figs. 18–21): coxae sparsely setose, setae long. Femora with surface sparsely setose; setae long. Protibia with 3 teeth, basal tooth small, dorsal surface with a line of setae from base to apex. 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.
