Austin, Travis County, Texas, USA
November 13, 2010
Size: 9mm
Found by spider enthusiast Joel Hallan in his home. This spider has a strong preference for vertical surfaces. I would chase it around and around the outside of the jar, trying to get it onto a flat surface for photographing. Whenever I enclosed it with another container, it would immediately take to its vertical surface. This repeated in the 2nd photo session as well.

Maevia poultoni -- is my hunch
Hi Joe,

Nice specimens (and images) -- wouldn't mind getting a closer look at these under the microscope!

Relying on Robert J. Barnes's description (1955), I would say that the large size, the large median epigynal opening, and the location all point to Paramaevia poultoni. (Perhaps someone else is willing to confirm or deny.)

I will add that his description doesn't quite match in all respects to this specimen (although certainly in the key points -- e.g., the thin oblique lines on ventral distal end of femur I), but this is most likely because he was describing preserved specimens, and as you know, salticids in particular, look much different when viewed under the microscope).


[I should add that the latest edition of the World Spider Catalog still includes the species under Maevia -- I suspect this is because Hill has already transfered some of Barnes's Paramaevia specimens back to Maevia. So this should really be Maevia poultoni, for now.]

Thank you!
Thank you Kevin! Maevia poultoni was our best guess going in. I'm hearing indirectly from someone that this could also be a "new species" that's been found further north in Texas. Not sure what that means yet - probably means new-to-Texas.

Sounds interesting -- let us
