Neoperla occipitalis (Pictet) .

The distribution of this species is generally east of the Mississippi River across to Maine and south to South Carolina (Stark 2004). DeWalt et al. (2002) first recorded the species from Illinois from a single female from Vermilion River drainage of eastern Illinois. Grubbs (2004) tentatively listed the species from Indiana, but Stark (2004) provided a historical record from Petersburg.

We present a second historical Indiana record. IN, Warren Co., 6/30/1935, D.W. LaHue, ♂ (PERC) .
