The New Synonymy of the Spider Genus Argyrodes (Araneae: Theridiidae) and a Description of a New Species from Japan

Abstract

The spider genus Spheropistha Yaginuma, 1957 is newly synonymized with the genus Argyrodes Simon, 1864. A new species of the genus is described from Japan. It can be easily separated from the closely related Argyrodes melanosoma (Yaginuma, 1957), comb. nov. by general appearance.
