Type material. Holotype male at IAVH labeled: “ Colombia, Tolima, Mariquita. / Trampa de Luz. / 5º 15’ 00.43” N; 74º 55’ 01.71” W. / 380 m. 23-X-2005. Coll. J.C. Neita Leg.”

Type locality. Colombia, Tolima, Mariquita.

Description of holotype. Male. Length 7.83 mm, width 3.81 mm. Head, pronotum, elytra, venter, and legs dark brown. Head ( Fig. 25 ): surface convex, setose, densely punctate; punctures small (0.16– 0.02 mm); interocular width 0.7 mm. Eye canthus rounded with sparse, long, slender setae. Frontoclypeal suture well defined, complete. Clypeus parabolic; surface concave, densely punctuate; punctures moderate in size (0.022–0.040 mm) ( Fig. 25 ). Clypeal margin reflexed. Clypeal ventral surface setose, setae slender and long. Labrum reduced, conical, setose; setae moderately long. Labium with poorly developed ligule, prominent. Maxillae with galea poorly developed, lacinia not developed, maxillary palpus with 4 palpomeres; palpomere 4 as long as 1–3 combined. Antennae with 9 antennomeres; antennomere 1 robust; antennomere 2 globose; antennomeres 3 and 4 with base cylindrical, apex broad; antennal club with 4 antennomeres with few setae ( Fig. 25 ). Pronotum ( Fig. 25 ): Convex, wider than long at middle. Surface densely punctate, ocellate, setose; punctures moderate in size (0.02–0.05 mm). Marginal bead present; anterior margin concave, with membrane; lateral margins nearly smooth, setose; setae hair-like, long; posterior margin slightly defined at middle. Anterior angles rounded; posterior angles broadly rounded. Scutellum ( Fig. 25 ): Surface opaque, densely punctate, setose; punctures ocellate, moderate in size (0.015–0.025 mm), center smooth; apex rounded. Elytra ( Fig. 25 ): convex, elongate, subparallel. Surface opaque, densely punctate, setose; punctures moderate in size (0.04–0.06 mm); setae long, hair like. Elytra with 4 striae, interstriae well developed, wide. Elytral margins setose; setae long, hair-like. Hind wings: subcostal and radial veins 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 and 2 not connected, not forming a basal cell. Venter: prosternal process absent; slightly concave on sides, surface with dense setae; setae slender, short, tawny. Mesosternal surface sparsely setose, slightly concave at middle. Metasternal surface densely punctate, ocellate, setose; setae slender, long; metasternal apex divergent at middle. Abdomen with 3 exposed ventrites medially; ventrite V longer than ventrite IV; prepygidium slightly convex at middle. Pygidium: recumbent; surface densely punctate; punctures ocellate, setose; setae slender, moderately long. Legs: 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 carinae, carinae with 4–5 spine-like setae; apex semicircular, transversely truncate. Tarsal claws bifurcated, symmetrical. Genitalia ( Figs. 26 a-b): parameres simple, symmetrical, elongated, tapered toward apex; parameres shorter than phallobase, with a setose sulcus on outer surface; phallobase slender.

Female. Unknown.

Distribution. The species is known only from the type locality, which is a tropical dry forest from the inter- Andean valleys of Cordillera Oriental in Mariquita, Tolima, Colombia ( Fig. 29 ).

Locality records. (1 adult, male). Colombia: Tolima, Mariquita.

Temporal distribution. October.

Diagnosis. Males of this species are easily distinguished from E. pentaphylla by the following combination of characters: Antennal club with 4 antennomeres, antennomeres 3–5 slender, cylindrical; antennomeres 3 and 4 similar in length, antennomere 5 longer than 3 and 4; elytra with 4 striae, striae widely separated. The unique form of the parameres, which has a sulcus from base to apex on outer margin, is also diagnostic.

Etymology. We are pleased to name this species after the senior author’s (JCN) father Pedro Antonio Neita Rodriguez.

Natural history. All that is known about the natural history of this species is that the only known specimen was attracted to lights in a dry forest in the Colombian Andes at 380 m ( Fig. 28 ).
