Etymology

The genus ''Crosbycus'' is named after the arachnologist Cyrus Richard Crosby (1879–1937). Gender masculine.

Taxonomy

The genus ''Crosbycus'' securely contains one species ''C. dasycnemus'', although historically several other species have been proposed to belong to the genus. These include ''C. goodnighti'' Roewer, 1951, ''C. pentelicus'' Roewer, 1951 and ''C. speluncarum'' Roewer, 1951. ''C. goodnighti'' Roewer, 1951 was indicated as ''species inquirenda'' by Cokendolpher & Lee 1993, and arguably "should be deleted from North American faunal lists" (per Shear, 2008). For other species from Eurasia, the affinies are even less certain, notably ''C. pentelicus'' was considered a junior subjective synonym of ''Nemastoma thessalum'' Simon, 1885 by Rambla (1968). Another, ''C. speluncarum'' Roewer, 1951, might be best considered ''nomen dubium'' (after Schönhofer 2013).
