Culoptila costaricensis Flint 1974a: 9 .

This species is superficially most similar to C. unispina, n. sp. Both species have a similarly shaped phallobase, elongate and parallel­sided with an elongate projecting posterodorsal apex, and also a relatively short, apically acute tergum X. It differs from C. unispina in possessing 2 phallic spines rather than 1, and also by possessing shorter inferior appendages and a slightly shorter tergum X.

Adult. Length of forewing: male 3.5 mm. Color yellowish­brown in alcohol, appendages paler. Mesothorax of male not noticeably modified; mesoscutal wart short, heart­shaped; mesoscutal setae short. Mesothoracic tegulae of male rounded, small, unmodified; tegular setae short; tegular gland not discernable.

Male genitalia. Sternum VI process short, subtruncate. Tergum IX ventral margin rounded, tapered from anterolateral margin, distinctly produced posteroventrally. Inferior appendages short, subacute apically. Tergum X short, about as long as wide, apex in ventral view narrowed, subacute; ventrolateral processes with apices incurved and posteriorly bent, bend preapical and relatively weak, inner margin of apex subacute. Phallobase elongate, dorsal and ventral margins subparallel in lateral view, apicodorsal projection elongate, straight, apex acute. Phallic apparatus with 2 phallic spines, elongate, about 3/4 length of phallobase, narrow, subequal in length, one nearly straight, the other strongly recurved at base.
