Segestria help

Is this a Segestria senoculata or is it Segestriabavarica?

[No.9 Spider]

I'd personally go for Segestria florentina at first glance, but will look again shortly.

Well I have many Segestria florentina living around my patio doors and windows, in fact I have seen dozens of them recently, but none with such blatant markings. Mostly they appear black but have very faint markings upon close inspection, certainly not like this guy

I agree that spider in photo does not look like a S.Florentina mainly because its abdomen is too light and has such obvious markings.

After looking at pictures of segestria senoculata i would say it looks like your spider is indeed most likely segestria senoculata

Few S. florentina have a distinct marking and usually appear black, though if you look very closely you'll sometimes pick up a feint pattern on the dark ones.
S. bavarica is more like S. senoculata in appearance, though larger and light grey in colour and relatively indistinct abdominal pattern and doesn't have the 'front end' of your specimen which I think is distinctly S. florentina.

If this is a S.florentina how come the abdominal pattern is so light and so visible. All the other specimens I have seen are like the pic below. Sorry to ask so much, Im just trying to understand a bit more

I will want to retract my earlier assesment... this spider you have is a S.Florentina.... if you look at the legs they have some metallic shine to them.

also this spider in this picture shows the pattern on a S.Florentina

your spider is more likely a juvenile as the adults are said to be almost completely black.

I dont dispute anyones ideas, as I clearly am not an expert lol. I have seen juvenile and adult S.florentina and in my cases they have always appeared black and up close are a very dark brown (all over) with faint patterning. This pic is just confusing me as the abdomen is so pale. It feels like a S.florentina has had its front chopped off and stuck to the abdomen of another Segestria species, lol.

Other than juvenile, is there any other reason a S.florentina would have such a pale abdomen? I know spiders shouldnt really be Id by there abdomens (in most cases) as they are very variable, but this is a huge variance compared to all other specimens I have come across

hmmm..... perhaps a florentina got its groove on with another species of Segestria

[sebastianbawn]

Thats a thought! I know Tegenaria seem to enjoy mixed-species relations!
