Allocapnia illinoensis Frison .

Frison (1935) described this species from a disjunct population in Clark County in southeastern Illinois. Otherwise , the bulk of its distribution occurs in the upper Great Lakes region, eastern Canada, and from scattered locations in the Appalachian Mountains (Ross & Ricker 1971, DeWalt et al. 2010). Despite numerous attempts to recollect the species from and near the type locality, no new specimens have been found. Consequently , Webb (2002) and DeWalt et al. (2005) have listed it as extirpated from Illinois. Grubbs (2004) stated that although Finni (1973), Bednarik & McCafferty (1977), and Stewart & Stark (2002) each listed A. illinoensis from Indiana , no specific literature records or museum specimens had been found.

We present one population from northeastern Indiana and a second from central Indiana ca. 90 km northeast of the type locality.
