Alepia copelata Quate, 1999: 422 –423, figs. 3E–F.

Type material. Argentina . Misiones province. Corpus. 27º7’51.03’’ S; 55º30’26.46’’ W, male, 29.VI.2005. CDC light trap. Leg. Stetson ( MLP).

Diagnosis. Interocular distance equal to the width of 6 or 7 ommatidia. Aedeagus symmetrically bifurcate, branches of aedeagus narrow at base, widening at apex, with a small constriction subapically, terminating in a triangular lobe.

Description. MALE: Head: rounded. Eye bridge composed of 3 facet rows, interocular distance equal to the width of 6 or 7 ommatidia; medial margin of eye bridge angulate, but may be tapered to the width of only 1 facet on medial margin. Interocular suture arched. Patch of setae alveoli on vertex divided medially. Antenna: scape cylindrical, 0.5 times longer than wide (0.14 mm), pedicel spherical (0.07 mm), flagellum with 14 fusiform flagellomeres. Flagellomere 14 with apiculus, smaller compared to preceding flagellomeres. Ascoids not distinguishable from setae on the slide-mounted specimen. Palp segment 1 shorter than remaining segments, palpus formula = 1.0:2.1:2.4:2.9.

Wing: Measures of length and width: 2.32 mm and 0.85 mm respectively. Wing membrane infuscate with a pattern of lighter spots along the wing margin, with small bristles distributed evenly across the surface of the wing; base of veins R2+3 and M1+2 with small darker spots; also with darker spots at apices of all veins except R5; R5 ending at wing apex; Sc short (0.19 mm).

Male terminalia: Hypandrium reduced, only a post-hypandrial plate present, wider at the apex than at the base, rectangular; aedeagal apodeme ovoid; gonostylus two times longer than gonocoxite, sligthtly curved, hooked apically; cerci triangular, narrow apically and wide basally, without apical tenacula, with two apical spines and large spines along the inner margin; cluster of accesory tenacula inserted in dark elliptical area near the base of cerci; tenacula with umbellate tips; aedeagus forked, 2.5 times longer than gonocoxite, wider at apex than at the base, sclerotized, dark. Both arms of the aedeagus are of similar shape, slender at the base and widening at the apex, with a slight constriction near the apex, ending in a triangular lobe. Epandrium hardly visible due to the position of the specimen on the slide-mounted. Hypoproct poorly visible, ending in a rounded shape.

Distribution: Panamá, Barro Colorado Island; Argentina , Misiones province.
