Isoperla quinquepunctata (Banks)

( Figs. 12 View Figs a-d)

Chloroperla 5-punctata Banks 1902.

Holotype ♀, New Mexico, Las Vegas, Gallinas River .

Isoperla patricia Frison 1942 .

Holotype ♂, South Dakota, Lawrence County, Spearfish River, Spearfish .

Male. Aedeagus: sclerotized posterior process absent; body of aedeagus with a small posteromedian lobe covered with minute spinulae, one posteroapical lobe, one dorsal lobe, and an anterior lobe ( Fig. 12a View Figs ). Posterolateral margin of ninth and tenth terga with patches of long stout setae, fewer and smaller on tergum ten ( Fig. 12c 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 gradually to blunt apices ( Fig. 12c View Figs ). Vesicle: rounded lobe, widest at base with broadly rounded apical margin ( Fig. 12d View Figs ), sometimes appears constricted along inner sclerotized lateral margins with wider and broadly rounded membranous outer lateral margins.

The live everted aedeagus agrees generally with the previous description ( Szczytko & Stewart 1979, fig. 36). In this study, the small lobe A is covered with minute spinulae ( Fig. 12a View Figs ) vs. devoid of spinulae ( Szczytko & Stewart 1979, fig. 36 D), and a truncated dorsal lobe C is present ( Fig. 12a View Figs ) vs. absent in Szczytko & Stewart (1979, fig. 36).

Isoperla quinquepunctata , a geographically widespread western Nearctic species ( Szczytko & Stewart 1979) is most similar to I. acula and I. mormona ( Table 1 View Table 1 ). See comments under I. acula .
