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

Taxonomy

Many species in this genus used to reside in Achaearanea, which received a major revision in 2008. The genus was originally established as a subgenus of Theridion.

Cryptachaea

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. C. veruculata was introduced to Europe from New Zealand.
