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 View Figs ); the distance between the lobes is consistently ca. equal to lobe width ( Fig. 30 View Figs ). 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 View Figs ); the dorsal margin is essentially straight ( Fig. 27 View Figs ); in caudal view the specilla bear prominent troughs from near the base to the tips, giving a distinct concave appearance ( Figs. 28–29 View Figs ); the medial margin of the trough has low, tooth-like tubercles present along the distal ⅓ ( Figs. 28–29 View Figs ). The subanal lobes are broadest basally, slightly recurved anteriorly in distal ½, and subequal in length to the specilla ( Figs. 27–28 View Figs ). The vesicle base is short, body expanded medially and ovoid in shape, and entire surface covered in long, socketed bristles ( Fig. 31 View Figs ).

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 View Figs ). The subgenital plate terminates in large, broadly rounded or subtriangular lobes separated by a vshaped notch ( Fig. 32 View Figs ).
