03AAFB7E6A0AFF8ACAA8F920EFADFCDC.taxon	description	Adult. A distinct sclerotized line is present on the meso and meta thorax that intersects the center of the large U-shaped mark at the base of the segment. This appears as a W in contrast to the U commonly seen in Suwallia and makes it easy to separate adults quickly. Male. Five basal segments of cerci modified into clasper-like structures (Figs. 1 - 4). First segment very large, curved outward and heavily sclerotized (Fig. 4), with large inward directed, triangular – shaped process at base (Figs. 4, 7). Segments 2 - 5 smaller, forming stout inward pointing lobes, sharp apically, and bearing many large setae, which cover irregular grooves (Figs. 4, 7). Ninth segment enlarged, about length of segments 7 and 8, tergum covered by large plate-like structure (Figs. 3, 8), base broadly rounded, tapered to narrow pointed tip, which extends anteriorly to segment 8 (Figs. 3, 7). Lateral margins of tergum 10 formed into inward curved lobes, bluntly truncate apically, with irregular grooves, bearing few long hairs near base, with narrow patch of shorter hairs near apex (Fig. 6). Aedeagus. Stout and capped by dorsal medial hump, when recurved, composed of densely compacted hair-like structures. Aedeagal base with pair of sclerotized hook-like processes that are visible through the ventral cuticle of sternum 9. Processes composed of numerous flat sclerotized tubercles that join together to form a comma-shaped structure (Fig. 9). Female. Cerci with first segment elongate, much longer than remaining segments and slightly concave inwardly (Fig. 10). Larvae. Head and prothorax heavily covered with long hairs (Figs. 11, 12). Basal cercal segment of mature larvae long, with whorl of stout setae that is not associated with segment margins (Fig. 15). Egg. Collar with two layers and chorion smooth.	en	Baumann, Richard W., Lee, Jonathan J. (2014): Neaviperla Is A Valid Stonefly Genus In North America (Plecoptera: Chloroperlidae).
