Identification

Det. P. W. Messer, 2013 (based on microscopic examination of this specimen)
Distinguished from juxatapostional species in Ball & Anderson (1962) by combination of:
large size (elytra length = or > 8 mm)
elytra without (or rare) punctulae
hind tarsi dorsally impunctate and glabrous (or rare setae).
The latter diagnostic character I find especially useful. Other large Pseudoophonus have hind tarsi with obvious dorsal pubescence or at least show numerous punctulae under high power. (per Peter W. Messer, 26 January, 2013)
Range
AZ-TX-OH-ID (+PA?) / AB-SK / Mex. (1)
Habitat
primarily a prairie species (1)
