Isoperla namata Frison View in CoL .

States bordering Illinois, except Iowa and Wisconsin, support populations of I. namata ( Frison 1942; Poulton & Stewart 1991; DeWalt et al. 2010). As noted above, there is some doubt about the taxonomic boundary and distribution of this species. A single Illinois female in the INHS collection has been tentatively identified as I. namata by S. W. Szczytko. A male paratype from Indiana was re-examined and the aedeagus everted revealing two basal spurs and confirming the existence of this species in the state.
