I collected this insect near Pena Blanca Lake during Bugguide Gathering 2013. I've ID'ed it as Parabacillus hesperus since the Parabacillus Info page states that it is found in southern AZ, and that the only other species in our area (P. coloradus) occurs northeast of this.

Note that right leg II is significantly shorter than left leg II. This is developemental defect (vs. a perspective illusion). The specimen was desiccated with and retains a relatively flat profile. It is supported by two 0.003 inch diameter tungsten wires, to which it is glued with Bioquip #1157 insect repair adhesive on its dorsal surface.
