Abstract. Two new species of stoneflies, Haploperlaparkeri Kirchner and Kondra-
tieff and H.fleeki Kondratieff, Kirchner, and Lenat, are described from Haywood Co.,
Macon Co., and Hoke/Moore Co., North Carolina, USA, respectively. Diagnostic char-
acters are given to separate these two species from the three other known eastern North
American species of Haploperla.
