Mexitrichia rancura Mosely, 1954: 345   .

This species is most readily diagnosed by the unique wing-like appendages of the phallicata. The short, apically invaginated inferior appendage and relatively short paramere appendages are useful ancillary characters. The species is only known from the type specimen, with the genitalia mounted as a slide preparation, in a more or less dorsoventral orientation. An illustration of the lateral view is found in the original description, which was used, in part, in the following description.

Adult. Length of forewing: male 4.0 mm. Forewing with forks I, II, and III, hind wing with forks II and III. Color (wing setae) brown. Wing bar at anastamosis lacking pigmentation, distinctly evident. Ventral process of abdominal segment VI (male) short, ventrally oriented, subtriangular, subacute apically, not constricted basally.

Male genitalia. Segment IX nearly evenly rounded anterolaterally, length greatest midlaterally, posterolateral margin forming rounded or slightly angular projection in dorsal half, narrowing ventrally; segment deeply mesally excised dorsally and ventrally, dorsal excision narrow, much less than half width of segment. Tergum X with acute mesal projection and projecting lateral lobes, lateral lobes with apices narrowed, acute, and mesally curved. Inferior appendage short, concave apicomesally, without apicomesal projection; basolaterally, with rounded projection on each side; mesal pockets of inferior appendage with apical processes short, dorsally curved. Paramere appendages relatively short, emerging from membranous lateral projections, sinuously incurved, apices slightly expanded, acute. Dorsal phallic spine weakly sinuous in lateral view, apex nearly linearly projecting, not strongly upturned; as viewed dorsally with apex acute. Phallicata with distinct inflection, dorsally with apicolateral, setose, wing-like projections. Endophallic membrane with single prominent curved spine.
