Culoptila montanensis Flint 1967: 2 .

This species is most similar to Culoptila vexillifera , n. sp. In both species the large, inflated phallobase has a laterally flattened apodeme extending from its anterordorsal margin. This apodeme is short and subtriangular in C. montanensis , but very elongate and rounded in C. vexilliferea . An additional difference is that the phallic spine of C. montanensis is considerably shorter than C. vexillifera .

Adult. Length of forewing: male 3.5 mm. Color dark brown; wing with small whitish mark at arculus, anastomosis indistinctly marked. Mesothorax of male not noticeably modified; mesoscutal wart obscured by pin. Mesothoracic tegulae of male with elongate setae, not evidently modified (specimen on pin); 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 moderately long, subtruncate apically. Phallotremal sclerite heavily sclerotized. Tergum X short, length slightly less than width, apex in ventral view truncate to subtruncate; ventrolateral processes with apices incurved, nearly planar in caudal view, mesal margin acute; apices not or scarcely posteriorly bent. Phallobase large, broadly rounded in lateral view, anterior margin compressed and keel­like, extending dorsally to form acute, trianguloid projection, apicodorsal projection moderately elongate, straight, apex subacute. Phallic apparatus with 1 phallic spine, very short, about 1/4 length of phallobase, weakly sinuous, widened at middle.
