Supplementary description.

Male terminalia directed caudally. Tergite 9 fused with gonocoxite at base (Fig. 26C View Figure 26 ); caudal margin of tergite 9 with prominent lateral lobe, finger-like in lateral view (Fig. 26C View Figure 26 ), elongated, triangular in dorsal view (Fig. 26A View Figure 26 ); posterior margin with additional small, triangular outgrowth (Fig. 26A View Figure 26 ). Sternite 9 membranous (Fig. 26B View Figure 26 ). Gonocoxite 1.3-1.5 × longer than tergite 9 (including lobe); ventral lobe relatively small, triangular both lateral and ventral views, covered by few setae (Fig. 26B, C View Figure 26 ); inner surface of gonocoxite with hairs, proximal corner with hairless, paler area (Fig. 26A View Figure 26 ). Gonostylus simple, tapering to distal end. Aedeagus complex very large, 1.8-1.9 × longer than gonocoxite, in lateral view (Fig. 26C View Figure 26 ); ejaculator apodeme large, not covered by paramere in lateral view (Fig. 26F View Figure 26 ); tip of interbase directed inward in dorsal view (Fig. 26D View Figure 26 ), and ventrally in lateral view (Fig. 26F View Figure 26 ); dorsal lobe between interbases small, membranous, hardly noticeable (Fig. 26F View Figure 26 ); aedeagus long, trifid, median branch slightly shorter (Fig. 26D-F View Figure 26 ); lateral branch prolonged ventrally/caudally (Fig. 26F View Figure 26 ); tips of branch flattened; sperm ducts branching from elongated portion of sperm pump, branching area dark (Fig. 26F View Figure 26 ).

Female terminalia: Tergite 8, ~ 1.7-1.8 × wider than tergite 9 in lateral view (Fig. 27B View Figure 27 ), not divided medially (Fig. 27A View Figure 27 ). Triangular sclerite ~ 1/4 of length of tergite 10; sclerite separated from tip of tergite 10; lateral lobe of tergite 10 medium sized, 2 × as long as wide, with few long hairs (Fig. 27B View Figure 27 ). Cercus wide, with blunt notches on dorsal, close to tip and ~ 1/3 of mid-length on ventral margin. Hypogynial valve relative long, dorsal margin close to tip concave (Fig. 27B View Figure 27 ). Common spermathecal duct recognisable; sperm ducts simple, narrow tubes, (Fig. 27C View Figure 27 ); three round spermathecae with curved, suddenly tapering ducts (Fig. 27D View Figure 27 ).

Distribution: Canada and USA from (Alberta to Newfoundland, south to South Dakota, South Carolina and Georgia) ( Oosterbroek 2021).
