Stonefly Species Soliperla sierra (Roachflies)

Male aedeagus. The structure and similarity of the aedeagus for this species to that of Soliperla campanula was documented by Stark (1983). Both species have a median row or grouping of relatively short, thick setal-spines on the ventral aedeagal surface (Fig. 10), and both have an anterolateral lobe with a close-set cluster of several additional short, thick setal spines (Fig. 11). The organization of the ventral setal-spine grouping for Soliperla sierra is not clearly in two well-organized rows, whereas in Soliperla campanula the two median rows are usually distinct. In addition, the anterolateral spine clusters are set on partially sclerotized lobes for mature specimens of Soliperla sierra, but these lobes are membranous for specimens of Soliperla campanula we have examined. Larval abdominal pigment pattern. The larva of Soliperla sierra is similar in body size and general features to those of known species. However, in the small sample available to us, the abdominal pigment pattern appears distinct from that of other Soliperla larvae known from California. Prominent, median longitudinal pale spots on terga 3, or 4 - 6 form an almost continuous median pale stripe on those segments. Tergum 7 often has a well defined circular median spot and the lateral pale spots on tergum 5 are much smaller than those on terga 2 - 4 (Fig. 15).Source: California Soliperla Ricker, 1952 (Plecoptera: Peltoperlidae), Distribution And Taxonomic Characters
