( Figs. 13 View Figs a-d)

Isoperla rainiera Jewett 1954 View in CoL .

Holotype ♂, Washington, Pierce County, Mount Rainier National Park.

Male. Aedeagus: sclerotized posterior process present; body of aedeagus with one small posterior lobe, one dorsal lobe, and one anterior lobe ( Fig. 13a View Figs ); sclerotized process length <0.5 mm, recurved, crescent shaped, apex broadly rounded with two lateral sharp hook-like projections directed anteriorly ( Figs. 13 View Figs a-c). Abdominal terga 8-9, 9, 9-10: without stout spinulae or long stout setae. Posterolateral margins of at least abdominal segment 8 with scalelike 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 sharp apices ( Fig. 13c View Figs ). Vesicle: pedunculate, length subequal to width, constricted near base with curved lateral margins, wider and rounded at apex ( Fig. 13d View Figs ).

Isoperla rainiera shares several characters with species of the I. sordida complex ( Table 1 View Table 1 ). It differs from these species in paraproct shape and aedeagal characters. The paraprocts taper gradually to sharp apices and the apex of the sclerotized process is crescent shaped. This species is not known from California, recorded from Oregon and Washington ( Szczytko & Stewart 1979).
