Ornixolinae
Ornixolinae is a subfamily of leaf-mining micromoths within Gracillariidae, established in 2001. Members are characterized by specialized genital structures including hindwings with small frenular bristles along the costa in both sexes, a dorsal flap on tergum VIII in males, and a sclerotized semicircular female lamella antevaginalis. The subfamily contains approximately 30 genera distributed globally, with notable radiations in Australia, Hawaii, and Asia. Larvae are endophytic leaf miners that create diagnostic mine forms including serpentine, linear, and blotch patterns.
