Help with Washington state spider ID

[GWENHA]

This large spider was found in an outdoor shed in the city of Edmonds WA. Size is approximately 3 inches, and the color is black with the brown markings on abdomen. Can you tell me what kind of spider this is?

 

[loxoscelesfear]

Eratigena atrica, other names Tegenaria duellica or T. gigantea

 

[The Snark]

Eratigena atrica, other names Tegenaria duellica or T. gigantea

Or T Agrestis (aka Hobo). Both been introduced in the Pacific north west and are now well established.

I would say T, Dullica house spider or T,Agrestis,..Although most of them look the same?? to a degree, I've got one T,Dullica+False widow sp just now both around 3-3.5" leg span and another female Dullica in my gallery from 2013, she produced an egg-sac that i let them all free last year.

Soz my post maybe confusing lol.

It does look exactly like T,Dullica (house spider) that has been all over the EU/US etc and is a UK spider from what i know, all they need is food and nice temperature they are hardy and can live almost anywhere,, given the abdomen pattern i'll get a pic of mine 2 moz and put it I'm my gallery, could be the same or completely different.

Other than what i said in my post.. I do agree with The Snark.

There is no such thing as T.duellica. It's E.atrica now.
Also Mark, your post is a bit hard to understand or are you claiming to have a 3" false widow?

 

[MarkmD]

Hanska T, Dullica does exist and mostly a UK spider, look up wiki page etc or even my T gallery on here. well unless its changed its name for some strange reason its still T, Dullica?? (to me) and they very vicious spiders that grow large as a UK house spider plus have migrated a lot.

I do understand the "to me" factor. But for some reason is, if I'm not too wrong DNA-tests that found T.gigantea, T.atrica and T.duellica to be the same species and not that related to other Tegenaria so it got a new genus.

 

[MarkmD]

Ok the (to me) is T,Duellica was always the name since i was 5-6 yr old and I've had house spiders/True spiders/OW and NW between that time now I'm 28, that's why it's name to me is the same, you are right as each genus is from a different continents although the family do consists of being the same spider but different abdomen pattern's, I did have a false widow sp but sadly she died last year after having her over 11 months.

Oh Hanska they are all family members in some respect, Hobo spider, Gigantea, Duellica.

 

[Hanska]

I've got false widows and the real ones but 3"? Must have been a typo.

 

[The Snark]

Let's just leave it at Eratigena. Snerk snerk.

 

[GWENHA]

Thanks! Always something new to learn on arachnoboard. I have read that the E. Aratica keep the Hobo's from being house spiders. The males kill other Hobo males. This is clearly a male, so maybe he is an old Hobo warrior. Good information everybody.

That is definitely a giant house spider (Eratigena atrica). there are Thousands of these spiders across Western Washington. Also the spider is a female. (males have longer legs and have diff. pedipalps than females.) these spiders spin funnel webs to catch prey, but i think they are a bit lazier than grass spiders, grass spiders can spin a huge web in 1 DAY !!!!:wideyed:
