Diagnosis

Male imago.

Female imago. (1) Forewing veins C, Sc and R 1 areas brown pigmented ( Figure 26G View Figure 26 ); (2) marginal intercalary veins single ( Figure 26G View Figure 26 ); (3) hind wing hyaline ( Figure 26H View Figure 26 ); (4) costal process of hind wing compound ( Figure 26H View Figure 26 ); (5) abdominal sterna with black anterolateral marks ( Figure 26I View Figure 26 ).

Mature nymph. (1) Labrum with small medial emargination (fig. 1 in Salles et al. 2003); (2) distal margin of labrum with long and simple spine-like setae (fig. 1 in Salles et al. 2003); (3) maxillary palp subequal in length of galea-lacinia; (4) glossa subequal in length than paraglossa; (5) forefemur with short spine-like setae near ventral and dorsal margin (fig. 8 in Salles et al. 2003).
