in males; dark areas on dorsal pronotum and on lateral lobes; uncommon; central mountains
|Top view of pronotum||Hind femur||Tegmen|
[Hind tibiae of specimens of Psoloessa spp. from Arizona occasionally are orange; Psoloessa lacks large rectangular cells on tegmina and has dark spots largely confined to a longitudinal central row; spots on tegmina of Stenobothrus are scattered.]
G' Lateral carinae of pronotum absent, or marked by color but not by structure.

[Phlibostroma quadrimaculatum may key to this point if the lateral foveolae of vertex are determined to be visible from above. The three or four large, distinct, dark spots on the tegmina will indicate P. quadrimaculatum.]
H' Lateral carinae absent; hind femora usually with bands on outer face; cells of tegmina irregular in shape; pronotum may be dark brown; wings may be pale blue or colorless; widespread in eastern Colorado but usually not abundant.
