Nymphs of four western Nearctic Sweltsa species (Plecoptera: Chloroperlidae)

Associations were made for four species of western Nearctic Sweltsa nymphs, and a comparative study of selected specimens was initiated to locate characters that might have potential systematic value. Nymphs of S. fidelis (Banks), S. pacifica (Banks), S. revelstoka (Jewett) and S. townesi (Ricker) w...

Description
Summary:Associations were made for four species of western Nearctic Sweltsa nymphs, and a comparative study of selected specimens was initiated to locate characters that might have potential systematic value. Nymphs of S. fidelis (Banks), S. pacifica (Banks), S. revelstoka (Jewett) and S. townesi (Ricker) were successfully distinguished using chaetotaxic features of cerci, mouthparts and femora in combination with pigment patterns of the frons.
