Subgenus Zimmermannia

Zimmermannia Hering, 1940: 266 . Type species Ectoedemia liebwerdella Zimmermann, 1940: 264 by original designation and monotypy.

Diagnosis. Most species relatively large for Nepticulidae, wingspan 6–10 mm. Colour pattern either absent or restricted to small dorsal spot and rarely a costal spot. Vestiture often rather dark brownish. Males often with conspicuous humeral lobe on hindwing around hairpencil, females often with very hairy abdominal tip. Pale headed species may resemble Trifurcula species, but males of those always with velvet patch of raised scales on hindwing underside or black androconials on forewing underside (in T. (Glaucolepis) melanoptera Van Nieukerken & Puplesis, 1991). In females genitalia dissection may be necessary when the venation is not clearly seen.
