Mexitrichia rovira Flint 1974

Mexitrichia rovira

This species clearly belongs to the leroda group, and is probably most closely related to M. leroda Mosely. From this species, M. rovira differs in lacking all processes from the venter of the aedeagal complex, and in possessing a large spine internally in the aedeagus.

ADULT.—Length of forewing 2.5–3 mm. Color in alcohol brown. Sixth sternum with a short, compressed mesal process. Male genitalia: Ninth segment rounded anteriorly. Tenth tergum in lateral aspect produced into a darkened apical point, and a small ventrolateral lobe; in dorsal aspect with a broadly U-shaped apicomesal excision. Aedeagal complex with a dorsomesal process, whose tip is slender and upturned, and a pair of long, slender lateral appendages, which are widened subapically and end in a sharp point; central tube apicodorsally produced into a sharp point, with an internal, apical sclerite curled in lateral aspect; basoventrally with a pair of short, rodlike appendages and a small, thin, curved plate, whose apical margin is slightly bilobed in ventral aspect.

MATERIAL.—Holotype, male: PANAMA, CHIRIQUI: David, Rovira, 13 July 1964, A. Broce, USNM Type 72734.
