Achaearanea is a genus of comb-footed spiders that was first described by Embrik Strand in 1929. It used to include the extremely abundant common house spider, which was transferred to genus Parasteatoda in 2006, together with many other species. A. veruculata and many more species were moved to genus Cryptachaea in 2008. Others were moved to the revived . The genus was thus reduced from about 150 species to about 22 species during major revisions. Possibly even more species should be transferred to other genera.
