''Attulus inexpectus'' was first described in 1997 by Dimitri Logunov and Torbjörn Kronestedt (as ''Sitticus inexpectus''). The specific name ''inexpectus'' means "unexpected"; the species was separated from '' Calositticus rupicola'' (then ''Sitticus rupicola''), the authors stating, for example, that all spiders previously identified as ''S. rupicola'' in England were in fact the new species ''A. inexpectus'' (then ''Sitticus inexpectus''). The two species can be distinguished by the pattern of white hairs on theDistribution and habitat
''Attulus inexpectus'' is found from southern England through central and northern Europe (Germany, Austria, Sweden, Poland, Estonia and Russia) to central Asia (Kazakhstan and Kyrgyzstan). It is a lowland species (thus contrasting with ''A. rupicola''), typically found near to water, either coastal or inland. In southern England, where the species is found from April to October, it lives in coastal shingle and tidal litter, often adjacent to saltmarshes.References
