( Figs. 16 View Figs a-d)

Isoperla sordida Banks 1906   .

Holotype ♂, California, Los Angeles.  

Male. Aedeagus: sclerotized posterior process present; body of aedeagus with two posterior lobes, one dorsal lobe, and one anterior lobe ( Fig. 16 a View Figs ); sclerotized process length approaching 0.5 mm, partially recurved and rod-like, apex expanded, flattened and projecting dorsally in lateral view ( Figs. 16a View Figs ), bifurcate subapically with two ventrally directed rounded lobes in posterior view ( Fig. 16b View Figs inset), width of lobes 0.18-0.20 mm. Abdominal terga 8-9, 9, 9-10: without stout spinulae or long stout setae. 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 gradually to long blunt apices ( Fig. 16c View Figs ). Vesicle: rounded lobe, widest at base with broadly rounded apical margin ( Fig. 16d View Figs ).

Isoperla sordida   has been recently collected in two high elevation (above 1524 m), spring fed or snow melt eastern Sierra Nevada streams ( Sandberg 2011b); and shares similar characters with other species from the I. sordida   complex and I. umpqua   ( Table 1 View Table 1 ). It is most similar to I. denningi   . See comments under I. denningi   .
