Description
editSchizocosa mccooki is a large wolf spider with the body length ranging between 9.1–15.5 mm (0.36–0.61 in) for males and 9.6–22.7 mm (0.38–0.89 in) for females.[6] The carapace ranges in color from gray to light brown with a pale median band, black lateral bands, and pale submarginal bands that sometimes extend to the margins.[6][7][8] The dorsum of the abdomen typically has a demarcated heart mark and dark transverse bars with a series of paired white spots, while the lateral areas are mottled yellow, brown, and black, with a few oblique black lines.[6][7][8] The venter ranges in color from reddish-brown to dark orange, but may also have may extensive black areas, particularly under the abdomen.[6][7] Males and females have similar appearances, with the exception of darker tipped forelegs in females.[10]
Similar species
editS. maxima and S. mccooki are virtually indistinguishable except by size.[6] S. maxima have a body length ranging between 16.1–20.3 mm (0.63–0.80 in) for males and 21–28.4 mm (0.83–1.12 in) for females.[6][7] Recent phylogenomic work suggests that S. maxima may be a junior synonym of S. mccooki, however formal nomenclatural changes are pending future studies.[9]
Habitat
editS. mccooki are widespread in open habitats such as grasslands, chaparral, the desert, and pinyon pine forests, among others.[7][8] Some populations of this species have been observed digging burrows.[11][8]
