Genus Lasius Fabricius ^HNS

A close relationship between Acanthomyops Mayr ^HNS and Lasius ^HNS has long been recognized (Creighton 1950a, Wilson 1955a, Wing 1968a). Recent molecular studies (Savolainen 2002, Janda et al. 2004) demonstrate that Acanthomyops ^HNS is nested phylogenetically within Lasius ^HNS. To maintain monophyly for Lasius ^HNS, Acanthomyops ^HNS cannot be treated as a separate genus. It is here returned to the status of subgenus ( stat. rev.) in Lasius ^HNS, which generates revised or new combinations in Lasius ^HNS for the following species names: arizonicus ^HNS comb. rev., bureni ^HNS comb. nov., californicus ^HNS comb. rev., claviger ^HNS comb. rev., clavigeroides ^HNS comb. rev., colei ^HNS comb. nov., coloradensis ^HNS comb. rev., creightoni ^HNS comb. nov., interjectus ^HNS comb. rev., latipes ^HNS comb. rev., mexicanus ^HNS comb. rev., murphyi ^HNS comb. rev., occidentalis ^HNS comb. rev., parvula ^HNS comb. rev., plumopilosus ^HNS comb. rev., pogonogynus ^HNS comb. rev., pubescens ^HNS comb. rev., and subglaber ^HNS comb. rev.
