A List of the Species of Craspedolepta Enderlein Recorded from North America (Homoptera: Psyllidae: Aphalarinae) Louise M. Russell Systematic Entomology Laboratory, Agr. Res. Serv., U. S. Department of Agriculture, Beltsville, Md. 20705 ABSTRACT Craspedolepta is recognized as a valid genus. The list of North American taxa assigned to the genus includes 53 specific or varietal names. Of these, 35 names are treated as representing valid taxa and 17 represent misidentifications, synonyms or nomina nuda. Thirty new name combinations are proposed. In this article I recognize Cras- pedolepta Enderlein as a valid genus distinct fxom. Aphalara Foerster, reassign to Craspedolepta 2 North American species placed in the genus by Enderlein but excluded from it by American workers, and propose 31 new name combinations for Nearctic species or varieties originally placed in Aphalara and here transferred to Craspedolepta. I also dispose of 17 names that represent misidentifications, synonyms or nomina nuda, but I do not comment on the validity of presently recognized species or indicate new synonymy. My purpose is to modernize the nomenclature of one group of North American Psyllidae, and thus provide more meaningful names to persons concerned with this group of psyllids. Enderlein (1921) established the genus Craspedolepta and designated Aphalara artemisiae Foerster (1848) as its type- species. He also transferred the Nearctic species angustipennis Crawford and veaziei Patch from Aphalara to his new genus. With the exception of these 2, North American species that are con- generic with artemisiae have invariably been described in Aphalara, and have not been transferred to Craspedolepta. The reason for the disregard of Craspedolepta by Americans is not clear. It is unlikely that all American describers were unaware of the genus even though they did not mention it and continued to place angustipennis and veaziei in Aphalara. It is possible that Americans considered differences between species insufficient for separation into two genera, and choose without stating it, to ignore Craspedolepta. Craspedolepta and Aphalara are closely related and though most species are readily assignable to one or the other genus, a few North American species are placed less easily. Enderlein separated the genera on one unsatisfactory character, stating that the costa was not thickened distad of Ri in Craspedolepta, and that it was thickened distad of Ri in Aphalara . Later workers, including Dobreanu and Manolache (1962), Heslop-Harrison (1949), Loginova (1961, 1963), Von- dracek (1957) and Wagner (1947), have provided more reliable characters for the separation of the genera and have furnished new and useful information on the hosts, biology and relationships of members of the group. North American species of Cras- pedolepta can be separated from those of Aphalara as follows: Clypeus subglobose or pyriform, not tapered from base to apex, not approaching or attaining front margin of head; vertex merging smoothly into the slightly convex genae with- 156 J.
