Genus Ectoedemia Busck
Ectoedemia Busck, 1907: 97 . Type species Ectoedemia populella Busck, 1907: 98 by original designation and monotypy; see Van Nieukerken 1986: 75 for synonymy.
The genus Ectoedemia has been divided in five subgenera (Van Nieukerken 1986): the two treated here, Ectoedemia s. str., Zimmermannia Hering, 1940, further Etainia Beirne, 1945, Fomoria Beirne, 1945 and Laqueus Scoble, 1983 . Th e latter, which is also preoccupied, has later been synonymised with Fomoria (Van Nieukerken 2008; Puplesis 1994). Preliminary molecular analyses (E.J. van Nieukerken, personal data) indicate that the monophyly of Ectoedemia in this wide sense is problematic in relation to Parafomoria Borkowski, 1975 and Acalyptris Meyrick, 1921 . However, in all analyses, Ectoedemia s. str. and Zimmermannia remain closely related.
Diagnosis. The two subgenera here are recognised from other Nepticulidae by the collar comprising hairscales (lamellar scales in Stigmella and most Bohemannia), bifurcate Rs+M in hindwing (trifurcate in Trifurcula) and absence of uncus in the male genitalia. Males often have a hairpencil on the hindwing, forewing cilia line usually conspicuous.
