Dysdera sp, ID please

Hi Guys,
Iv'e taken a few shots of Dysdera sp , it was under the lid of the water butt along with 2 other species which I will post later, I am trying to Id it but I'm not sure if it's crocata or erythrina, It's a female, and on pic No3 I think there are spines on 4 femur,The last pic shows the underside but the epigyne isn't too clear, but lends itself more to erythrina, I can't get a site on line that can compare the epigyne of crocata to erythrina, I would apperciate any guidance, ..Cheers.
Duncan

I've enlarged the photograph as best as I can and there doesn't appear to be any dorsal femoral spines on femur IV which would put it being Dysdera erythrina.
You won't find any distinguishing epigyne in Dysdera species!

It's more widespread in the South, and does not occur as far North as Dysdera crocata, which although reaching into Scotland is quite sparsely distributed.

I have seen them in Scarborough (walking in the sunshine, eating ice cream

) and I have had them brought to me dead in Malton, so chances are that they could well be somewhere near you. They are very nocturnal and spend lots of time under things, so you might find one by searching. They are a great spider to find! (D. crocata)

Harsh but fair.

There is quite a good population in SBC nurseries, along with Lariniodes sclopetarius, Uloborus plumipes and lots of plants.

Actually, once the sea-fret goes it can be very nice.

Really nice shots of my favourite spider ( it eats woodlice hooray! )
Just look at those mandibles, armour piercing

I resent that!

(What's your "beef" with woodlice anyway?)

@Action_man: I'd say that the way you're looking for animals (woodlice etc) you should have an encounter sooner or later if they are around in your area. But maybe they're more inclined to "natural" habitats (a.o. to fresh pine boards

) - I seem to find them more in piles of (lime)stones, than under wood, but that may just be a correlation with the locations that I visited in the areas where they are to be found at all.
