Iridescent Salticid with Enlarged Palps and White Markings - Messua limbata

Iridescent Salticid with Enlarged Palps and White Markings - Messua limbata
Sedona/Oak Creek, Yavapai County, Arizona, USA
June 12, 2011
Found in the riparian corridor along Oak Creek. Basal section of the pedipalps was very noticeably enlarged and lengthened. Is this, then, a male? I saw another iridescent salticid in the same locale recently, tho it didn't have the enlarged palps (http://bugguide.net/node/view/516236). Curious if they could be the same species. Thanks for any help.

Nice find! I think Messua sounds accurate. The males of the genus are strongly iridescent and have long divergent chelicerae.

I notice your depth of field is quite shallow. If you're using a flash, you might want to stop your aperture down a bit smaller. Like if you're at f/5, try f/9 or f/10. For most lenses, you won't see much diffraction softening at this magnification until about f/13. If you're not using a flash, nevermind, as f/10 won't give you enough light.

 
Of course, if you're doing a
Of course, if you're doing a close-up of the spider's face or something, you'll probably need to open back up to f/8 or so, since diffraction softening gets much more noticeable after you pass 1:1 magnification.

Looks like something
in the Dendryphantinae for sure. Could it be Eris, Paraphidippus, or Metaphidippus? They all have species that look somewhat close.

male with long,
divergent chelicerae (not pedipalps) - makes me think of Messua http://bugguide.net/node/view/429098, and I believe that is fairly distinctive of this genus, though there are no images of males here.
