All males collected in northwestern Argentina and Bolivia, and the males compared with holotype by Flint at the National Museum of Natural History (NMNH) bears ventral and dorsal spines in the dorsal and ventral area of phallus (Figure 5J–L). In the original description of Martynov, the apex of phallus is invaginated as in Figure 5J,K.
