Soyedina washingtoni Group

http://lsid.speciesfile.org/urn:lsid: Plecoptera .speciesfile.org:TaxonName:50713 6

Three species are proposed for this group: S. carolinensis, S. merritti, and S. washingtoni . In ventral aspect the epiproct dorsal sclerite is open distally, revealing a sclerotized inner member which is flared apically, directed slightly to the left, and the flange lip is approximately the same size radially (Figs. 26–28, 36–38, 44–46). The paired ventral sclerites are asymmetric with right member distinctly longer than left (Figs. 25–26, 35–36, 43–44). The paired dorsal sclerites are also asymmetric (Figs. 29–30, 39–40, 47–48). The outer paraproct lobes are variable between species. This is mainly an Appalachian-distributed species group (Fig. 80).
