Caught this spider in Concarneau, France, last week. Any idea on the species? Sorry for the bad quality picture, I will try to get better ones if I see it out and about.
Spider from France - ID?

Segestria sp. (Segestriidae). Looks like a male, could be either S. senoculata or S. bavarica (im slightly leaning for the second). Got any clearer shots of the abdominal pattern?
hi,
just a guess because i am breeding segestria florentina.
the slings and juvs are looking quite similar than yours !
and it seems that your specimen just starts to get it's colour - take a look at the chelicerae, seems like there comes a touch of green like in s. florentina.
ciao, oliver
edit : maybe your location of found was to much in the north, s. florentina is a mediterranian species !

Hey Oli. 
Yeah i'm breeding S. florentina too, and the juveniles do look like S. bavarica up until the last molt (apart from the green chelicerae which im not sure of seeing in this specimen, might be wrong but it looks like the normal shine that is in the other 2 species). However, they appear to have darker legs and prosoma, though that is probably not always the case.
I didnt say S. florentina to begin with cause i was thinking this specimen to be a mature male (judging by the lenghts of the legs I). However we can't really be sure unless we see the palps.
I agree with you anyways, that we should leave S. florentina as a possibility.
By the way, S. florentina is not strictly Mediterranean, in the sense that it can be found also in most of central Europe, including the Uk where it was introduced.

Thanks for the thoughts so far, i will try to get better shots soon. I am sure that it is not an adult male, there are no bulbi on the pedipalps yet. I might have overlooked them if they are very small in this species?
How do you keep yours? I have this one in a semi-moist setup right now, but I am considdering giving it abit dryer surroundings with more ventilation.
Edit: After looking at some pictures, I would say it looks alot like S. senoculata. The abdominal pattern does not look anything like the one on bavarica. None of the photos I made showed any green coloration on the chelicerae, they always look shiny black. But i will keep an eye on it when making more pictures.
Btw, do you know any good general literature on true spiders in europe? A "university-level" book would be realy nice.

The bulbs, if present, should be clearly visible. So apparently it's not a male, which makes everything harder. We have to consider all the 3 species, but i think it's not S. senoculata. More probably S. bavarica or a young S. florentina (as revilo stated). What size is it (bodylenght)?
As for the keeping part, its fairly easy. They are highly adaptable so no need to worry about humidity or venitilation (i dont even use substrate). They are crevice weavers. The best thing you can do is take a piece of wood, thick and wide enough, and drill a hole in it which the spider will use. Spray it once every while (i do so more frequently which juveniles, very rarely with adults).
