Abstract Pardosa albomaculata Emerton is found to be a distinct species (previously treated as synonym to P. groenlandica (Thorell)); comments are given on synonyms, variation and distribution. P. lowriei sp.n. is described on material from Washington state, USA, and British Columbia, Canada; P. bucklei sp.n. on material from Saskatchewan, Canada. P. albomaculata and P. lowriei are 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 and P. bucklei belong to the provisionally named glacialis/groenlandica complex, 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 in Pardosa species. Viewpoints on some species group characters are also given.
