Spider ID..

[james41777]

The spider was found in Stein Vally, BC, (canada..)
Replacing its first-left leg, it recently molted..really amazing with the regeneration thing!
Anyway.. can anyone Id this spider?

 

[Steven Gielis]

It looks like a lycosid to me.

 

[KUJordan]

it is indeed a Lycosid, but it'll be tough to ID to genus or species. Great spider though!

 

[james41777]

thanks alot for the answer!
oh by the way, the size is about 1.5 cm

 

[NRF]

It certainly doesn't give me the Lycosid. I think it more looks like Agelenidae. Don't know the sp. or genus though.

 

[NRF]

There is something Gnaphosidish over it as well. Would it be possible to get a close up of the eyes of the second pic?

 

[Steven Gielis]

The family Zoridae is also an option.

 

[lucanidae]

I don't see the Gnaphosid like spinnerets in the first pic... I don't have any better guess though. :?

 

[NRF]

Me too:?
I hope someone can figure it out.

 

[james41777]

I'll get a close up pic soon when I get the camera!
Thanks for all the answers!

I looked into Zoridae becuase I thought it was an excellent idea. They are characterized by two strongly recurved rows of eyes, and judging by the picture I don't see this. Also the front of the cephlathorax looks slightly wrong. However, if it is Zoridae, by locality it is one of four speices:

Katadysas pumilus Hentz, 1850
Catadysas pumilus Thorell, 1869

Anyone know what is going on with the two species listed above? Described 19 years apart by two different people with only one letter difference?

More likely to be a Zora...

Zora pumila
Zora spinimana

However, it dosen't look like Zora spinimana!!

I'm not ruling out Zoridae but until we get a better pic of the eyes..... hard to say.


Does anyone know any genera of Gnaphosids that don't display the normal conical and easily seen spinnerets?

 

[james41777]

thank u all for the identification.
I don't have the really good camera..
I might be able to get it tomorrow.
Sorry abou the delay with pix.
thank you

According to Platnick Katadysas pumilus Hentz, 1850 = Zora pumila (Hentz, 1850), and it is now placed in Zora. There seem to be no such species as “Catadysas pumilus Thorell, 1869”, at least not in Zoridae.

Of Zoridae I only know Zora, and I don't think this one looka like Zora, and I agree that it is not Zora spinimana. And if at the loc. in question only have four Zoridae which in fact are only two Zora spp., my conclusion is that it aint no Zoridae.
Waiting for more comments...:?

I photoshop zoomed in on the eyes and the don't look like Zoridae. Thanks for the taxonmic info on Zora spp. With that combined info I think we can rule out Zoridae now. How are we sure it isn't some weird Lycosid genus?

The eyes, my friend, the eyes.

Hallo,

Now, with the second picture i'm quite convinced that it's an Agelenid, Agelena sp.

1. , note that the posterior median eyes are behind the posterior lateral eyes (recurv), in Zorids and Gnaphosids it is vice versa.

   The posterior row of eyes can be either recurved, procurved or straight in Gnaphosidae. Anyway I can't really figure out which Gnaphosid genus would look like this. My first impression was also Agelenidae. But what species, what genus??? Rather short spinnerets. The specimen looks kind'a strange. :?
   May be we should try it on Bugguide and see if anyone of the arachnophils there can give us some clues.

 

[lucanidae]

I definitley agree with the spinneretes not being nearly long enough or apparent enough to be an Agelinidae. Just by the looks of it it seems to be some sort of ground spider. I'm still not sure what kind of Gnaphosid wouldn't show those characteristic spinnerets though. We've also ruled out Zoridae.... :? :? :? I'll be hitting the new Guide to North American Spiders today for inspiration.

 

[Spaceman_Spiff]

I don't want to press my opinion here, but this is ridiculous!
We can all agree that the spinerets are not really visible on these two pictures, so how do you rule out Agelenidae and on the other hand say it looks gnaphosidish?
I think the habitus fits and i've seen similar patterns on the ophistosoma of both genera Agelena and Tegenaria.

By the way, the spinerets are much more conspicuous in Gnaphosidae than in Agelenidae IMO!

I have not ruled out anything but Lycosidae and Zoridae. This one required a lot of loud thinking. My first impression, Ageleindae, was right. It's a Novalena intermedia, an Agelenid with rater short spinnerets. :worship:
