Culoptila tarascanica Flint 1974a: 9 .

This is in some respects a relatively nondescript species of Culoptila , with a short tergum X, only very slightly incised apically, and short, blunt inferior appendages. The most diagnostic characters are the shape of the phallobase, which is more or less inflated basally and has a straight­projecting posterodorsal apex, and the possession of a single short curved phallic spine.

Adult. Length of forewing: male 2.7–3 mm. Color brown; wing nearly uniformly colored, indistinctly marked at anastomosis by paler coloration, wingbar scarcely evident. Mesothorax of male narrow anteromesally; mesoscutal wart elongate, narrowed, rounded anteromesally; mesoscutal setae long. Mesothoracic tegulae of male flattened and weakly cupped, distinctly enlarged; tegular setae long; tegular gland present, length not ascertained because gland not everted.

Male genitalia. Sternum VI process short, subtruncate. Tergum IX ventral margin rounded, tapered from anterolateral margin, distinctly produced posteroventrally. Inferior appendages short, truncate apically. Tergum X short, length slightly less than width, apex in ventral view subtruncate, slightly concavely rounded; ventrolateral processes with apices incurved, mesal margin acute, or nearly so, apices slightly posteriorly bent. Phallobase large, very broadly rounded anteriorly, narrowing slightly posteriorly, lateral margins distinctly compressed in ventral view, apicodorsal projection moderately elongate, straight, apex subacute. Phallic apparatus with 1 phallic spine, short, about 1/4 length of phallobase, curved.
