A SUPPLEMENT TO THE GENUS ECTOEDEMIA BUSCK (NEPTICULIDAE: LEPIDOPTERA) IN NORTH AMERICA, DEALING WITH SOME DIFFICULT SPECIES AND ALSO SOME NEW ONES by CHRISTOPHER WILKINSON Department of Animal Systematics and Zoogeography, Vrije Universiteit, Amsterdam With nine text-figures Abstract This article attempts to shed light on some nomenclatorial problems in Ectoedemia. Since the mono-graph "The microlepidopteran genus Ectoedemia Busck (Nepticulidae) in North America" was written, approximately five hundred additional specimens have been made available which have provided new species and elucidated other information given here. Four problematic species are discussed, four new species are described and five significant specimens are detailed. Introduction In every major revision a few species names cause nomenclatorial problems. This is often because there is inadequate type material to check the names against, or no known specimens at all. The question of what to do with doubtful species usually arises during taxonomie revisionary work. The inclination is simply to cite them and leave them as doubtful in the forelorn hope that someone in the future will acquire more material. However, for the Nepticulidae it seems most unde-sirable to have doubtful species remaining in the literature when their identity has been suspect for more than one hundred years. Here the problems are explained, together with suggestions of how one might solve the doubtful identity of certain species. This is done with a view to seeking opinion, not only from other workers in the group but also of those who have dealt with similar situations. Four prob-lematic species in Ectoedemia are dealt with and another four in the revision of the genus Stigmella in North America (in press). One proposal, especially for those species described from a mine (no longer extant), with perhaps some vague reference to a larva, is to designate a neotype from an already known species — assuming that the descriptions of early stages agree. The two names then become synonymised and remain so, because of the neotype designation, and the former vague status disappears. The disadvantage is that in these cases the species may become known by the hitherto doubtful species name, if that is the older. A further suggestion which has been made to me and is an extension of the same idea, is that all already synonymised species lacking type 93
