1F042B4C6109FF9AFC23FE91FDBEFA5C.taxon	description	Male. The dorsal abdominal process of the 8 th abdominal tergum emanates anteriorly, extending ca. ½ length of the segment and terminates on the posterior margin as a raised, bilobed process with small, distally rounded or subtriangular lobes (Figs. 13 – 15). The dorsal abdominal process of the 7 th abdominal tergum is nearer the anterior margin of the segment and raised as a bar with smaller, distally rounded lobes (Figs. 13 – 15). The paired dorsal processes exhibit variation, namely in the distance between lobes and “ scaly ” nature of the lobes that can be seen only with SEM (Figs. 13 – 15). The specilla are broadest medially in lateral view due to an expanded keel, noticeably thickened in dorsal ½, and taper very little distally (Figs. 1 – 6); the outer margin has low, tooth-like tubercles present along the outer distal ⅓ (Figs. 7 – 12); in caudal view the basal ⅓ is concave (Figs. 7 – 9, 11). The subanal lobes are widest basally, narrow and tapering slightly along entire length, slightly recurved anteriorly in distal ½, and extend nearly to the distal tip of the specilla (Figs. 1 – 6). The vesicle base is short, body expanded medially and ovoid in shape, and entire surface covered in long, socketed bristles (Fig. 16). Female. The 8 th abdominal sternum bears a prominent, broadly-rounded medial tubercle on the anterior ½ that occupies the medial ca. ½ of the segment (Figs. 17 – 26). The subgenital plate terminates in large, broadly rounded or subtriangular lobes separated by a v-shaped notch (Figs. 17 – 26).	en	Grubbs, Scott A., Wei, Summer (2017): Morphological Systematics Of Leuctra Duplicata Claassen, 1923 Species Group (Plecoptera: Leuctridae).

1F042B4C610FFF98FEC9F994FB6DFA0D.taxon	description	Male. The dorsal abdominal process of the 8 th abdominal tergum emanates anteriorly, extending ca. ½ length of the segment and terminates on the posterior margin as a raised, bilobed process with small, distally rounded lobes (Fig. 30); the distance between the lobes is consistently ca. equal to lobe width (Fig. 30). The 7 th abdominal tergum lacks dorsal processes, bearing only a thin, unraised sclerotized band anteriorly. The specilla are very broad basally and medially in lateral view, tapering distally to an acute apex (Fig. 27); the dorsal margin is essentially straight (Fig. 27); in caudal view the specilla bear prominent troughs from near the base to the tips, giving a distinct concave appearance (Figs. 28 – 29); the medial margin of the trough has low, tooth-like tubercles present along the distal ⅓ (Figs. 28 – 29). The subanal lobes are broadest basally, slightly recurved anteriorly in distal ½, and subequal in length to the specilla (Figs. 27 – 28). The vesicle base is short, body expanded medially and ovoid in shape, and entire surface covered in long, socketed bristles (Fig. 31). Female. The 8 th abdominal sternum bears a broadlyrounded medial tubercle on the anterior ½ that occupies the medial ca. ½ of the segment (Fig. 32). The subgenital plate terminates in large, broadly rounded or subtriangular lobes separated by a vshaped notch (Fig. 32).	en	Grubbs, Scott A., Wei, Summer (2017): Morphological Systematics Of Leuctra Duplicata Claassen, 1923 Species Group (Plecoptera: Leuctridae).
