Black Widow 1 - Latrodectus mactans

Black Widow 1 - Latrodectus mactans
Cass County, Texas, USA
April 30, 2008
Size: 1/2 inch
Not sure if this is a male or a female. I suspect that what appears (at first glance) to be very bulbous bulging eyes are actually pedipalps and therefore it is a male but I do not known if males have the red hourglass shape on the bottom. Any help is appreciated..

After some further research
I an inclined to believe it is a Southern Black Widow (Latrodectus mactans).

its
a mature male but i couldnt say which species of widow it is

 
yes
agreed, and it's also correct about the pedipalps. However, I believe you may have 3 different species of Widow in TX. I'm not sure how to distinguish between them either. If you don't get a comment from Jeff H. or someone else who knows for sure in the next few days, you should move this to the widow guide page here. That way it won't get buried and forgotten in the ID Request.
