Mexitrichia leroda Mosely, 1937: 158 .

Mortoniella leroda is superficially most similar to, and most likely to be confused with M. mexicana , n. sp. It differs in a number of details, including the much shorter apicolateral processes of tergum X, the distinctly asymmetrically curved apicomesal process of the inferior appendage, and the possession of distinct, paired phallotremal spines, as well as a short ventral endophallic spine, both absent or inconspicuous in M. mexicana .

Adult. Length of forewing: male 3.0– 3.4 mm. Forewing with forks I, II, and III, hind wing with forks II and III. Overall color (in alcohol) medium brown. Wing bar at anastamosis not evident. Ventral process of abdominal segment VI (male) short, ventrally oriented, rounded to subtruncate apically, not or only slightly constricted basally.

Male genitalia. Segment IX nearly evenly rounded anterolaterally, length greatest midlaterally, posterolateral margin forming rounded 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 slightly produced mesal projection, or mesal margin nearly evenly excised, and projecting lateral lobes; lateral lobes short, subacute apically, slightly mesally curved. Inferior appendage with distinctly asymmetrically developed apicomesal projection, apicomesal projection narrow, relatively short, tapering and acuminate apically; basolaterally, with short, acute or subacute projections on each side; mesal pockets of inferior appendage with apical processes short, dorsally curved. Paramere appendages elongate, narrow, bases somewhat enlarged and cupped, incurving from membranous basolateral lobes, distinctly flattened over much of length, somewhat wider in distal half, acuminate apically. Dorsal phallic spine slightly enlarged basoventrally, articulating with depression in dorsal margin of phallicata, distinctly upturned apically; as viewed dorsally, with apex very narrowly acuminate. Phallicata tubular, with slight depression dorsally, sclerotized region extended ventrally, basoventrally with minute microsetae, dorsally without projections. Endophallic membrane elongate, ventrally with short spine near apex of phallicata, apicodorsally with distinct paired phallotremal spines.
