BG2269 E0016 - Zygoballus nervosus - male

BG2269 E0016 - Zygoballus nervosus - Male
Baton Rouge, Brookhollow Drive, East Baton Rouge Parish, Louisiana, USA
April 6, 2008
Size: body length 3.4 mm.
In April 2008, I received my new Canon 40D and rushed outside with a sweep net to find a test subject. I shortly collected a small non-descript Salticid and ran some test shots. Some time later, closer examination of these images suggested a more interesting creature than I had initially supposed. Unfortunately, I had failed to photograph key
features that might lead to a positive ID, and the specimen was no longer available.
Visible features suggest an adult male Zygoballus. If this is correct, it does not match Z. rufipes or Z. sexpunctatus. This leaves Z. nervosus. I could find no images of an adult male Z. nervousa, but the white stripe beneath the eyes is similar to that seen on some BG images of a female Z. nervosus. If it is a subadult Zygoballus, I suppose it might be any of the three species know for the US. If it is not Zygoballus, suggestions as to the correct genus would be of great interest to us.
Comments/confirmation/correction would be most welcome.

Zygoballus nervosus
After seeing specimens of all three species, I'm certain that this is a male Zygoballus nervosus. It's generally more of a northern species, but specimens have been reported from Mississippi and Arkansas. Compare with Dick Walton's recent specimen (confirmed by pedipalp analysis):

I would agree with Zygoballus
You said he was no longer available... did you release him?

 
subadult perhaps
If it is Zygoballus, I would suspect it is immature due to the relatively small chelicerae.
