Spider ID please?

[Allyn]

This spider is currently sitting in a glass in my kitchen. It was found in a wooden box I bought off ebay. It is brown, about an inch long including the legs and had has two lighter brown triangles on its back: the one nearest its head is slightly larger. Below the smaller triangle is a light brown brown dash, smaller than both triangles.

Many thanks.

I would go with false widow spider, Seatoda nobilis.

Looks more like Steatoda grossa, rather than S.nobilis.
It's a native species, just pop it somewhere dark, like your attic or shed.

They're selling some strange things on ebay then!

I too would suspect nobilis though it would be handy knowing the size of it (leg's exluded).

Are we looking at the same books?
Although I've chosen strong patterned images, they can vary quite a bit - some almost losing all patterning and looking quite black.
First off, where are you in the UK Allyn?

Steatoda nobilis still has a limited distribution (though it will be spreading northward due to the climate):

Steatoda grossa is more common and widespread (comparatively)

Obviously, arguing is fairly pointless as you can't confirm from a photo, you'll need to see the epigyne for confirmation.

It doesn't matter so much as to were he is from what does matter is were the box he ordered came from as that is were the spider was located.

S.nobillis are bigger we have a few in our conservatory and one of them (think it might have been killed earlier in week) has a body length of apprx 20mm. And i do live in a location were they are and have been well established for over 100 years.

Steatoda grossa will have 3 triangular patterns on its back.

Steatoda Nobilis has a mosaic pattern rather then the 3 triangles.

I hope this helps you in distinguishing the two.

This is infact a S.Grossa and not Nobilis as i had first said.
