03C087BC815DFFD7FE98FDD7DECB1C5C.taxon	discussion	Remarks and Distribution. Previous descriptions of the larva of this species are adequate. The first description was provided by Smith (1917). Claassen (1931) later provided a more detailed description. This species can be reliably separated from other members of the genus based on the presence of the conspicuous abdominal projections on abdominal segments 1 - 8 (Figs. 13, 14), the lack of a prominent acute lateral projection on the mesothorax (Fig. 15), and the acute angle (APP> 55) of the anterior pronotal projection (Figs. 15, 17). The distribution of this species extends from Canadian Maritime Provinces south to Alabama (Nelson 2000).	en	Myers, L. W., Kondratieff, B. C.

It can be separated from larvae of other Pteronarcys based on the absence of lateral abdominal projections (Figs. 18, 23), welldeveloped, acutely pointed pronotal projections (Figs. 20, 23), pointed triangular wing pads (Figs. 21, 23), and a pointed, semi-lunate, conical supraantennal process (Figs. 19, 22).

The geographical range of this widespread species extends from eastern North America south to Florida and Louisiana and across Canada to Alaska (Earle 2009, Nelson 2000, Stewart & Oswood 2006).

03C087BC814FFFC7FC27F8A9D93D1CAE.taxon	discussion	Remarks and Distribution. This species ranges from Quebec south along the Appalachians to West Virginia and Kentucky (Nelson 2000). Larvae of this species are most similar to P. scotti but can be distinguished by the spines on the abdominal segments. In P. proteus, spines of AB 1 - 7 are well developed with the largest projections possessing a convex outer margin and appearing hook-shaped in dorsal view (Figs. 51, 54, 57). When viewed laterally, the spines of AB 5 - 7 are well defined, rugose, triangular shaped projections, the dorsal edge projecting caudally, parallel to the lateral surface of the segment (Figs. 50, 53). Measured in dorsal view AB- 4 POM / SW ≥ 0.15; AB- 6 POM / SW> 0.12 (Care should be used in the use of these ratios due to marginal overlap in observed measurements with P. scotti) (Figs. 10, 51, 54). Live and recently preserved specimens also possesses a distinctive median yellow antennal band that is absent in P. scotti (Figs. 56, 57).	en	Myers, L. W., Kondratieff, B. C.

03C087BC814BFFC4FC0DF97CD9E1193A.taxon	discussion	Remarks and Distribution. 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 AB 5 - 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 AB 4 POM / SW <0.15; AB 6 ≤ 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).	en	Myers, L.
