Studies on Species of HolarcticPardosaGroups (Araneae, Lycosidae). I:Redescription ofPardosa albomaculataEmerton and description of two new species from North America, with comments on some taxonomic characters

Abstract

AbstractPardosa albomaculataEmerton is found to be a distinct species (previously treated as synonym toP. groenlandica(Thorell)); comments are given on synonyms, variation and distribution.P. lowrieisp.n. is described on material from Washington state, USA, and British Columbia, Canada;P. buckleisp.n. on material from Saskatchewan, Canada.P. albomaculataandP. lowrieiare closely related, differing in certain features of the male palps, notably the shape of the conductor, the terminal apophysis, and the embolus, as well as details of the epigynes. These two species andP. buckleibelong to the provisionally namedglacialis/groenlandicacomplex, including several Nearctic and Palae‐arctic species still not investigated in detail taxonomically. Comments are given on some taxonomic characters in the copulatory organs. In this respect emphasis is given to the importance of the shape of the mentioned palpal parts, which have hitherto been very little studied inPardosaspecies. Viewpoints on some species group characters are also given.
