Ochrotrichia moselyi Flint 1972

Ochrotrichia (O.) moselyi

As mentioned above, this and the preceding species are very closely related. O. moselyi may be recognized by the lack of the elongate, pointed lobe ventrally on the claspers, and in possessing only a single dark dorsal seta on the tenth tergum. However, the remaining structures of the tenth tergum and claspers appear to be identical in the two species.

ADULT.—Length of forewing, 2 mm. Color fuscous, antennae and head with white hairs; forewing with a transverse white band at midlength, white spots on anterior and posterior margins at ¾ length, and at tip. Male genitalia: Ninth tergum depressed, slightly expanded anteriad. Tenth tergum with a long, curved, dorsal process bearing basally a large black seta; left side with an apically forked process; ventrally with a scooplike lobe. Clasper with an elongate, fingerlike, dorsal lobe, midventrally with 3 heavily sclerotized spines differently placed on right and left claspers, basal portion considerably widened. Aedeagus long, threadlike.
