Genus Aulocara

Aulocara Scudder, 1876. Type species: Aulocara coerulipes S.H. Scudder, 1876 (= Aulocara elliotti)

Oedicara Scudder, 1876. Type species: Oedicara strangulatum S.H. Scudder, 1876 (= Aulocara elliotti)

Coloradella Brunner von Wattenwyl, 1893 [synonymy based on original description; no type designated; no species listed]

Drepanopterna Rehn, 1927. Type species: Aulocara femoratum Scudder, 1899

Large rounded head; long dark antennae; pronotum usually with pale margins on top pinched closer in middle (vaguely "X"-shaped); median carina very low and weak, cut behind middle by principal sulcus; usually with pale stripe down middle of back (especially along top of folded wings); "knees" of hind femora (in adults) in large part dark (usually nearly black); hind tibiae blue.

Closely related similar genera do not show the above combination of characteristics, though they may share some. Similar-looking Spur-throat Grasshoppers have a distinct "spur" between the bases of the front legs below.

Encoptolophus species can look similar, but have a low but distinct median carina on pronotum cut once at or in front of middle; the outer part of yellowish hind wings are clouded dark (wings are tranparent bluish in Aulocara).
