Diploperla robusta Stark & Gaufin .

This species is known from Illinois east to Connecticut and south to Alabama (Stark & Gaufin 1974; DeWalt et al. 2010). It was recently reported from Illinois ( DeWalt et al. 2005) and was listed by that state as “endangered” due to it inhabiting only a single springbrook system in east-central Illinois ( Illinois Endangered Species Protection Board 2009). This location appears to be its westernmost extent. Grubbs (2004) listed it from several counties in southern and central Indiana.
