Yagi, Sadahisa, Hirano, Nagao & Hirowatari, Toshiya, 2019, Taxonomic notes on the Ectoedemia suberis and angulifasciella species groups in Japan (Lepidoptera: Nepticulidae), Zootaxa 4706 (2), pp. 201-230 : 208

Ectoedemia angulifasciella group

Many species in the angulifasciella group utilize Rosaceae , and almost all the described Japanese species, except E. occultella and E. ortiva , are known to utilize Rosaceae . The adults usually have a shining metallic fascia, and males have a hair-pencil, which in some species is lost secondarily ( van Nieukerken 1985). In the male genitalia, the phallus has one pair of carinae, often with additional spines, and the valva has a more-or-less straight inner margin ( van Nieukerken 1985).
