Spider ID, No pic...yet

[Sheldy]

Hi all

I was chasing after an escapee roach today and ended up finding a little spier under my bed. However, I've never seen a spider like this before in England. Anyway, ive not got a camera at the moment, so i cant take any pictures but I can describe it and will get a camera on it ASAP.
It's about 2cm long - leg to leg, with a large abdomen, about 8mm accross and 5mm high, redish-brown in colour 2 large and 1 small dots/arrows accross its back. The rest of it is small and black and has a striking resemblance to a black widow.

Anyway, can anyone give me an idea into what species this may be? To be honest im a "little" uneasy about this as im arachnophobic...

it looks kinda like the Crustulina guttata...

Crustulina guttata is very tiny. Try with Steatoda grossa.

Searched that in google, this one looks almost perfect. Assumign it is that one, is it dangerous, is it native to England etc?

In Northern Europe it lives mainly inside, in cellars etc. Not rare in Southern Britain. In Southern Europe it perhaps lives in caves. I don´t know from where it has originated but it is now found all over the world and is apparently spread by man. It is not dangerous but it is a large (compared to other European species) Theridiid and some Steatodas are known to have very painful bites. See also my comment at

And when you google you will notice that the colour varies from completely black to specimens with several white or brownish triangles and other markings on its abdomen.
