Black Widow - Latrodectus

September 14, 2014
Sorry, no ventral view. I was thinking male black widow due to large palps, but the abdomen is round, which I have read is more typical of female.

is a well fed subadult male, probably was consuming beetle at bottom right of image.

Moved from Spiders.

Moved from ID Request.

Looks like a female
Latrodectus mactans to me.
