Western Palaearctic Ectoedemia (Zimmermannia) Hering and Ectoedemia Busck s. str. (Lepidoptera: Nepticulidae): five new species and new data on distribution, hostplants and recognition Author van Nieukerken, Erik Naturalis Biodiversity Center, Leiden, Netherlands Author Laštůvka, Aleš Mendel University of Agriculture & Forestry, Brno ,, Czech Republic Author Laštůvka, Zdeněk Mendel University of Agriculture & Forestry, Brno ,, Czech Republic text ZooKeys 2010 2010-01-08 32 32 1 82 journal article 10.3897/zookeys.32.282 d33a3344-7f9a-4028-8569-2b7643d9b43f 1313–2970 576594 9CACC88D-12A3-4FEC-948E-90365B649BB6 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. Checklist of West Palaearctic species
