Mexitrichia leei Flint 1974

Mexitrichia leei

This species appears to be closely related to M. atenuala Flint. Mexitrichia leei is distinguished, however, by possessing a thin basolateral lobe and only a single pair of lateral spines in the aedeagus.

ADULT.—Length of forewing 3.5 mm. Color in alcohol brown; forewing with a narrow, transverse white line at anastomosis; male fore and hind wing covered with flattened, scalelike hairs. Male genitalia: Ninth segment with anterolateral margin strongly produced and rounded; posterolateral margin strongly sclerotized and slightly flared. Tenth tergum in lateral aspect trianguloid in outline, with apex slightly produced, and with a midventral knoblike process; in dorsal aspect with apices truncate, with a lateral angulate shoulder and a deep U-shaped mesal excision. Aedeagal complex with apical half of dorsomesal process angled sharply dorsad, lateral process short, with apex angled Iaterad; central tube mostly membranous, with a pair of short sclerotized apicodorsal spines, basoventrally with a pair of short rodlike appendages, with a thin, narrow lobe laterally, with apicoventral angle produced into a sharp spine.
