Culoptila jamapa Bueno­Soria & Santiago­Fragoso 1996: 446 .

This is a distinctive species, most readily diagnosed by its phallic spines, both of which are elongate and narrow, and one of which has a row of spaced accessory spines near its apex and also a characteristic, enlarged, sclerotized base. The elongate, arched dorsal apex of the phallobase is also distinctive. The species is also characterized by males with only minimally developed tegulae and tegular glands.

Adult. Length of forewing: male 2.8–3.8 mm; female 3.2–3.8 mm. Color yellowishbrown in alcohol, appendages paler. Mesothorax of male not noticeably modified; mesoscutal wart short, subtriangular, wide at anterior margin. Mesothoracic tegulae of male flattened, only slightly enlarged; tegular gland present, very small, minimally developed.

Male genitalia. Sternum VI process short, subtruncate. Tergum IX ventral margin acutely angled, tapered from anterolateral margin, not produced posteroventrally. Inferior appendages short, narrow apically, divergent from base. Tergum X short, length slightly less than width, apex in ventral view subtruncate, slightly concavely rounded; ventrolateral processes with apices incurved, nearly planar in caudal view, mesal margin acute; apices not or scarcely posteriorly bent. Phallobase moderate in size, rounded in lateral view, apicodorsal projection arched, apicodorsal projection elongate, apex subacute. Phallic apparatus with 2 phallic spines, both very narrow and elongate, only slightly, sinuously curved; longer spine about 3/4 length of phallobase, shorter spine about 2/3 length of longer one; longer spine in apical 1/3 with row of short accessory spines, subequal in length, basally with abrupt sclerotized enlargement.
