Web of P. projectivulva

Cryptachaea is a genus of spiders in the Theridiidae (tangle web spider) family. ^[1]

Taxonomy

Many species in this genus used to reside in Achaearanea , ^[1] which received a major revision in 2008 by Hajime Yoshida. ^[2] The genus was originally established as a subgenus of Theridion . ^{[1] [2]}

Distribution

This is mostly a New World genus, with many species in South America. One species is cosmopolitan, one species occurs in the whole Palearctic, another only in China. ^[1] C. veruculata was introduced to Europe from New Zealand.

Name

The genus name is a combination of Achaea, the old name of the genus Achaearanea, and Ancient Greek κρυπτός "hidden". The genus is called Iwama-himegumo zoku in Japanese. ^[2]
