Steatoda lepida was first described in 1880 as Lithyphanteslepidus. In 1886, it was independently described again as Theridium triloris by Arthur Urquhart. In 1935, Elizabeth Bryant recognized T. triloris as a synonym of L. lepidus. S. lepida was independently described again in 1956 as Lithyphantes regius. In 1983, L. regius was recognized as belonging to the Steatodagenus and was subsequently named Steatoda regius. In 1994, S. regius was recognized as a synonym of L. lepidus and the two were merged to form S. lepida.
