Neotrichia gotera Flint 1983

Neotrichia gotera

This appears to be related to N. noteuna (Mosely) on the basis of the general form of the genitalia; however, N. noteuna bears only one long spine in the aedeagus and a long, heavily sclerotized internal tubule, which in lateral aspect appears to be a second spine. Actually, N. gotera and N. brevispina are much more closely related, as both bear two spines in the aedeagus. In N. gotera these spines are subequal in length and evenly tapering.

ADULT.—Length of forewing, 2.5 mm. Completely cleared, in alcohol.

Male Genitalia: Ninth segment with anterolateral angle produced into a long, slender process slighly upcurved. Tenth tergum membranous. Subgenital plate bearing a distinct ventromesal appendage at midlength. Bracteole membranous, slender. Clasper elongate, tapering in both lateral and ventral aspects. Aedeagus with a distinct spiral process; apical portion short, tubular with a distinct internal tubule and a pair of dark spines, subequal in length and evenly tapered.
