Isoperla mormona Banks 1920 .

Holotype ♀, Utah, Utah County, Vinyard.

Male. Aedeagus: sclerotized posterior process absent; body a long recurved tube with one small dorsoanterior lobe, tapering to a multi-lobed apex ( Figs. 10 View Figs a-b); a thin light dorsoapical band of fine spinulae concentrated somewhat above bi-lobed tip ( Figs. 10 View Figs a-b). Mesoposterior area of ninth tergum with bipartite patches of stout dark spinulae and long fine scattered setae, tenth tergum without spinulae ( Fig. 10c View Figs ). Posterolateral margins of at least abdominal segment 8 with scale-like setae clustered in brushes of several setae. Paraprocts: curved dorsally, length if straightened subequal to combined first and second cercal segments, tapering abruptly to blunt apices ( Fig. 10c View Figs ). Vesicle: trapezoid shaped, length subequal to width, constricted near base with tapered and straight lateral margins (base wider than apex), apex truncate ( Fig. 10d View Figs ).

Isoperla mormona is most similar to I. acula and I. quinquepunctata ( Table 1 View Table 1 ). See comments under I. acula .
