Diagnosis. Tegmina widened, apex rounded, posterior margin curved, forming an angle of 130° in cubital region ( Figs. 2 View FIGURE 2 and 6 View FIGURE 6 ), giving a unique aspect to this katydid among Microcentrini genera. Mesosternum and metasternum laterally compressed ( Figs. 1E View FIGURE 1 , 7E View FIGURE 7 and 10E View FIGURE 10 ).
