Perlesta teaysia Kirchner & Kondratieff .

DeWalt (2002) described P. napacola from eastern Illinois. In all respects it resembled P. teaysia with the exception of the egg, which lacked an erect egg collar, a structure clearly present in a scanning electron micrograph in the original description (Kirchner & Kondratieff 1997). Grubbs & DeWalt (2008) demonstrated that an erect collar was not characteristic of P. teaysia eggs, but were identical with those studied by DeWalt (2002) for P. napacola . Consequently, Grubbs & DeWalt (2008) synonymized P. napacola with P. teaysia . No additional populations of the species have been found in Illinois. Grubbs (2004) presented records for Harrison and Jackson Counties in Indiana.
