A 9 from Nebraska has the ocellar basin very poorly defined, but 

 otherwise seem to agree.

 the lateral lobes of the mesonotum are dark brown, not reddish-yellow.

 the broad, high middle carina the supraclypeal area is depressed into a 

 fovea ; clypeus truncate ; third joint of antennee ciliate beneath ; thorax
