(DNA analysis has been completed)

The verdict is:

   A new species  - Oecanthus walkeri - published in the May 2012 issue of Journal of Orthoptera Research


Male:  Note the pale green proximal portions of the limbs;  white mid-portions; and black distal portions.  Note the bright yellow eyes, the whitish pedicel and scape, and the black antennae.  Note the large amount of hemolyth pattern, and the macropterous character of the tail (long).  These characteristics were found on many of the individuals encountered thus far.



Note the nigricornis group type pattern of the antennal markings.



This is a female.


This female has a spermatophore attached.
