A revision of the genus Achaearanea (Araneae: Theridiidae)

Abstract

The genus Achaearanea Strand, 1929 (Theridiidae) is revised. Two genera, Henziectypus Archer, 1946 and Cryptachaea Archer, 1946, are revived from the synonymy of Achaearanea. Parasteatoda Archer, 1946 is recognized as an independent genus. Redefinitions and species lists of four genera, Achaearanea, Henziectypus, Cryptachaea and Parasteatoda, are given. Nine species of Henziectypus, 61 species of Cryptachaea, and 37 species and a subspecies of Parasteatoda, are respectively transferred from Achaearanea to the suitable genera.
