Phylum: Arthropoda
Class: Arachnida
Order: Araneae
Family: Theridiidae
Genus: Cryptachaea 

Cryptachaea is a genus of spiders in the Theridiidae (tangle web spider) family found around the world. 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. This genus includes small and large theridiids. The legs are medium long, with spines and usually many hairs. Their web is an irregular network of threads, usually in a sheltered place.

This is a small 4mm long spider of the genus Cryptachaea. It might be Cryptachaea blattea (a cosmopolitan species) as it has a wee bump on the rear of the abdomen that suggests it.
