Discussion. Keilbachia demissa is similar to K. scutica and K. flagrispina Mohrig by having its tegmen broadest subbasally, but it differs in having the mesial megaseta of the gonostylus much shorter and less strongly curved ( Figs. 5 View FIGURE 5 , 7 View FIGURE 7 ). Keilbachia demissa differs from K. flagrispina also by having the sensory pit of the maxillary palp much wider ( Figs. 1 View FIGURE 1 C, 2B).
