DeWalt (2002) described <i>P. napacola</i> from eastern Illinois, yet first reported this species as <i>P.</i> nr. <i>teaysia</i> in DeWalt et al. (2001). DeWalt (2002) indicated that <i>P. napacola</i> was distinct from <i>P. teaysia</i> only in the egg stage, noting that males and females of the two species were morphologically inseparable. <i>Perlesta teaysia</i> was later reported as new to Maryland (Grubbs &amp; Stark, 2001), Pennsylvania (Grubbs &amp; Stark, 2001) and West Virginia (Tarter &amp; Nelson, 2006) based solely on male morphology. Stark (2004), in his key to the Perlidae of the eastern Nearctic region, separated the males of the two species only by geographic differences (i.e., Illinois vs. Virginia). Grubbs (2004) and Tarter et al. (2006) have subsequently reported <i>P. napacola</i> from Indiana and Kentucky, respectively, based on SEM work with eggs. Eggs from multiple series of <i>P. teaysia</i> collections from western Maryland were examined recently with SEM, surprisingly revealing an identical pattern of chorionic sculpturing to <i>P. napacola</i> eggs, yet also very distinct from <i>P. teaysia</i>. This discrepancy raised a question regarding the true identity of <i>P. teaysia</i> because the Maryland location and the Virginia type locality both lay within the Ridge and Valley Physiographic Province. Eggs from paratype females of <i>P. napacola</i> were examined with SEM and compared to eggs from Indiana, Kentucky, and Maryland. Eggs were not present in the type series of <i>P. teaysia</i>, yet gravid females were collected in July 2008 from each of three sites near the type locality. The egg shape, collar characteristics and chorionic sculpturing pattern were identical for all eggs examined (Figs. 1–15), revealing that the egg depicted in Kirchner &amp; Kondratieff (1997; Fig. 10) does not represent the true <i>P. teaysia</i> and that <i>P. napacola</i> must be a junior synonym. The combination of (a) a long tubular aedeagus lacking a caecum, (b) dense, separated patches of sensilla basiconica on the 10 th tergum, and (c) paraprocts lacking a spine is now considered distinctive for the male of <i>P. teaysia</i>. The egg presented in the original description belongs to an undetermined species. In addition, it should be noted that the egg shown in Stark (2004; Fig. 7.407) for <i>P. teaysia</i> also is of undetermined identity. All previously documented records of <i>P. napacola</i> from Illinois (DeWalt et al., 2001; DeWalt, 2002), Indiana (Grubbs, 2004), and Kentucky (Tarter et al., 2006) are now referable to <i>P. teaysia</i>, while the collection from Tennessee represents a new state record.
