Tridentaforma
Tridentaforma is a genus of micromoths constituting the sole genus of the family Tridentaformidae. It was historically classified within Incurvariidae and Prodoxidae, but molecular studies led to its elevation to a distinct family in 2015. The genus currently contains two described species: T. fuscoleuca from California and western Canada, and T. browncopper from south-central British Columbia. Both are small moths with wingspans under 21 mm.
