Not H. unca?
I'm not entirely convinced about how you ended up with grisea. Brady (1964) says "the AME of H. grisea form a straight line with the ALE at their lower edges, but in H. unca the AME are below".

Doesn't it look like the small AME are lower here? (Oh, but for a front view.) I only nag because the location seems awfully close to Brady's H. unca cluster in map 5.

(H. grisea does, however, appear to be the far more common species.)

Hah, did you see Allen's comment on the AAS list? Guess that takes care of my second-guessing. :-)

Nope didn't see it
I was just focusing on the shape of the abdomen and the description of the carapace. H. unca didn't have the brown markings on the sides of the carapace in the description. What did they say on the AAS list? I'm not currently on it... got kicked off because of bouncing email and I haven't gotten back on yet.

Cameron and Hidalgo counties
Allen Dean wrote that "the species [unca] has only been collected in Cameron and Hidalgo Co. in south Texas".

Moved from Hamataliwa. I read descriptions for both other species and it doesn't match either.

Moved from Oxyopes. Based on eye arrangement & body shape this has to be Hamataliwa. It appears all three species are possible in that area of TX. I'll have to look at the PDF more closely to see if we can guess species. Right now I think body shape alone says it's H. grisea, but I don't know a lot about the other two species.

Aha, of course. Easy to forget about this genus, but you're right. (Funny to have only this dorsal view of such a photogenic genus.)

Moved from Spiders.

Oxyopes sp.
You can't see much of its characteristic posture and form from this perspective but I believe that is an Oxyopes species -- a lynx spider.

Looks adult, should be determinable or perhaps someone knows which species are found in your area?


In retrospect, I am not sure why I wrote that it looks adult... :-/
