Description

Schizocosa mccooki is a large wolf spider with the body length ranging between 9.1–15.5 mm (0.35–0.61 in) for males and 9.6–22.7 mm (0.37–0.89 in) for females.[5]

Similar species

S. maxima and S. mccooki are virtually indistinguishable except by size.[5] S. maxima have a body length ranging between 16.1–20.3 mm (0.63–.08 in) for males and 21-28.4 mm (0.82–1.11 in) for females.[5][6] Recent phylogenomic work suggests that S. maxima may be a junior synonym of S. mccooki, however formal nomenclatural changes are pending future studies.[7]

Habitat

S. mccooki are widespread in open habitats such as grasslands, chaparral, the desert, and pinyon pine forests, among others.[8] Some populations of this species have been observed digging burrows.[9][8]
