Nearctic Species of the Wolf SpiderGenus Trochosa (Araneae: Lycosidae)

This is the first in a projected series of systematic studies of the Nearctic Lycosidae described in the genra Trochosa and Lycosa.One important aspect of the proposed series of revisions will be an attempt to delimit generic taxa within the Lycosidae, with special reference to Nearctic species.Over 50 species of North American Lycosa have been described and most of the medium to large- bodied wolf spiders are included in this genus at present.However, preliminary studies indicate that several distinct species groups, which may well represent different genera, have been assembled
