Psilochorus is a genus of spiders in the family Pholcidae.

Description

The abdomen of Psilochorus species is humped and oval. The eight eyes are located in two rows.

Distribution

Most described species are found in the New World, especially from Mexico and the United States, but other species occur in South America. P. simoni is found only in Europe. P. nigromaculatus was described from New Guinea, but is certainly misplaced.

Name

The first part of the genus name is from Ancient Greek psilos "naked". The second part could be derived from a Greek word for "dance", or "separate".
