Adult Male - Arctachaea

This looks very similar to something else... I just can't remember what it is. I'd like to figure it out so I can add it to the "see also" info.

sorry...

I didn't find any other specimen in my samples from Norman Wells. Not even another male. I will send the male to Don Buckle at the end of the month. I'm sorry I couldn't help more.

Awesome !

You just solved my problem ! I have a male exactly like this one and I coudln't ID it correctly. Your pictures are perfect, I recognized my spider automatically. Do you know who might be interested to have some specimen in order to describe that species ? For now, I just have one specimen, but I still have more than 200 samples from this site to look at.

(I caught a male using a yellow pan trap placed like a pitfall trap in a wet habitat in june (14-17) 2011 in Norman Wells, NT, (65.25226, -126.66128))

Hi, Sarah,

That's great that you've found another one of these! I hope more of them turn up in your samples, including females.

Don Buckle is the guy you want to talk to. I'm not sure if anyone is working on describing this new species or not, but he'd probably know. Email me and I can give you his email address.

Hi John, Thanks a lot ! I'm

Hi John,
Thanks a lot ! I'm already in touch with Don. He is helping me with some of my Linyphiidae. I'm preparing a package for him with some specimen to Id. I will include that species.... hopefully with the female :D. If I found the female, I will post a picture of the genitalia on this website.
Regards,

I've been looking for other specimens this season, but so far none have turned up. I'd love to see the female. Hope you find one!

You're working on arctic spiders for your master's degree? I'd be interested in reading your thesis after it's done. :)

Hi, Thank you for your inter

Hi,
Thank you for your interest. My master is part of a big research program called Northern biodiversity program (http://insectecology.mcgill.ca/NBP/index.html). You can find a description of the different projects.Results will be published soon. I will present my results at the ESA annual meeting this year and most of the NBP crew will present at the ESC-AM. I've done half of my samples from Norman Wells and I didn't find other specimen. I'm still looking... I guess that now it's too late to find some in the field. I will try to have more informations on the habitat (type of plants, type of shadow...) so it might help you next year to find some.

… Sarah Loboda, 29 July, 2012 - 10:24am

Interesting! Neither nordica nor pelyx? Habitus looks similar to the one and palp to the other.

BTW, Levi synomized the genus with Chrysso in 1962:

Arctachaea Levi, 1957 = Chrysso O. P.-Cambridge, 1882 (Levi & Levi, 1962: 16)

Update: Nevermind -- just remembered your helpful information here:

One major difference in this specimen from either of those species is the abdomen, which does not have a turbercle of any kind. Instead, the abdomen is oval and rounded. I thought I was looking at a Theridion male of some type before seeing the palp.

You can bet I'll be double checking every little male theridiid/arctachaeid-like spider I find in my sweep net this year! I'd like to get some live habitus photos of this species.

… John Sloan, 16 March, 2012 - 11:46am

Nice find.

It has a very round carapace too.
