Perlesta shubuta Stark .

This species has been reported from Mississippi north to Illinois and Iowa ( Stark 1989; Poulton & Stewart 1991; DeWalt et al. 2001; Heimdal et al. 2004). Grubbs (2004) suggested that it might be found in Indiana.

We suspect that the Midwestern P. shubuta may represent an undescribed species. Comparison with one of Stark’s paratypes males strongly suggests this, but more comparative material from the type locality and elsewhere is needed. Nymphs of the Midwestern species have a head mask composed of small freckles. Nymphs of other regional Perlesta have a solid head mask. We present several Indiana records of this species.
