N.B.: type species designated by Thorell, 1869: 93, see also Levi & Levi, 1962: 28; considered a senior synoym of Eucharia C. L. Koch, 1835: 134 [urn:lsid:nmbe.ch:spidergen:05890] (type E. hera C. L. Koch, 1835 = Steatoda castanea (Clerck, 1757)) by Thorell, 1869: 93; Eucharia is preoccupied in Lepidoptera by Hübner, 1820 and was replaced by Acalanthis Gistel, 1848: IX [urn:lsid:nmbe.ch:spidergen:05891], which is itself preoccupied in Coleoptera by Erichson, 1844; considered a senior synoym of Stearodea F. O. Pickard-Cambridge, 1902d: 13 [urn:lsid:nmbe.ch:spidergen:05891] (type Aranea bipunctata Linnaeus, 1758) by Simon, 1903a: 990; considered a senior synonym of Asagena Sundevall, 1833 (revalidated by Wunderlich, 2008b: 198), Lithyphantes Thorell, 1869: 94 [urn:lsid:nmbe.ch:spidergen:05301] (type L. corollatus Thorell, 1869 = Steatoda albomaculata (De Geer, 1778)) and Teutana Simon, 1881a: 161 [urn:lsid:nmbe.ch:spidergen:05310] (type  Araneus castaneus Clerck, 1757) by Levi, 1957b: 375, and of Stethopoma Thorell, 1890a: 288 [urn:lsid:nmbe.ch:spidergen:05309] (type S. cingulatum Thorell, 1890), Ancocoelus Simon, 1895g: 150 [urn:lsid:nmbe.ch:spidergen:05298] (type A. livens Simon, 1895), Steassa Simon, 1910b: 192 [urn:lsid:nmbe.ch:spidergen:05308] (type S. mormorata Simon, 1910), Argyroelos Hogg, 1922: 288 [urn:lsid:nmbe.ch:spidergen:05299] (type A. micans Hogg, 1922) and Asagenella Schenkel, 1937: 380 [urn:lsid:nmbe.ch:spidergen:05300] (type Theridion erigoniforme O. Pickard-Cambridge, 1872) by Levi & Levi, 1962: 16-28; not a senior synonym of Moero O. Pickard-Cambridge, 1904 (Griswold, 1987b: 505); re-synonymization of Asagena (Murphy & Roberts, 2015: viii) not sufficiently justified and is not accepted here; Breitling, 2019b: 26 discusses Asagena and Crustulina to be subgenera of Steatoda (based mainly on COI, see FAQ 7).
