When viewed dorsally the projections of AB 1-7 in P. scotti are less developed than those observed in P. proteus , outer margins of largest projections appearing nearly straight in dorsal view ( Figs. 59 , 62 , 66 ). Viewed laterally the spines of AB5-7 appear as low rugose ridges that are nearly indiscernible, projecting past the posterior margin of the segment minimally in lateral view ( Figs. 58, 61 ). Measured in dorsal view AB4 POM/SW <0.15; AB6 ≤ 0.12 ( Figs. 10 , 59 , 62 ). Additionally, this species lacks the distinctive medial yellow antennal band that is present in P. proteus ( Figs. 64 , 66 ). This species is restricted to the Appalachians with records available from Pennsylvania, Virginia, North Carolina, Georgia, South Carolina , and Tennessee ( Nelson 2000 ). Fig. 62-65.
