Phidippus what? - Phidippus cardinalis

Phidippus what? - Phidippus cardinalis
McKinney Roughs Nature Park, Bastrop County, Texas, USA
July 29, 2010
Size: 8mm
I'd like to identify this critter from positively ID'd specimens, instead of comparing to pictures themselves identified by comparison to pictures, if possible. I suspect my photos don't provide enough info to ID from definitive keys.

I have the specimen, but I believe it's immature and plan to release it tomorrow.

Phidippus cardinalis
The only other reasonable possibility would be Ph. pius, but it should be mature now, and this is a subadult. Ph. cardinalis matures in the autumn, which looks about right for this specimen.

 
By subadult, do you mean penu
By subadult, do you mean penultimate? How can you tell? I'd like to know for myself. I assume it must be female, since the palps aren't enlarged. Thanks!

BTW, if you're G.B., we met at the Ohio AAS meeting. I was your collecting sidekick.

 
subadult/penultimate
I suspect G.B. identified it as subadult by a process of elimination. Younger Phidippus are generally yellow or yellowish brown, but begin to approach their true colors in the subadult phase. The specimen in your photographs is clearly not a mature female (no visible epigyne) and not a mature male (small pedipalps and chelicerae). Thus it is probably a subadult.

 
Similar to a Phidippus from Austin
I have a similar looking subadult Phidippus that I collected in Austin earlier this year. I believe it is P. cardinalis (as I suspect yours is). I'll post it to bugguide as soon as it matures along with the immature and subadult photos.
