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

Taxonomy

[edit | edit source]

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

[edit | edit source]

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.

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]
