Martarega oriximinaensis was described from Pará State (Figure 14B). This species is apparently more closely related to M. hungerfordi . This species shares with M. oriximinaensis the hind trochanter with a sharp concavity at its distal end (compare Figures 6D,E and 7B ) and a median narrow stripe not bifurcated at apex of hemelytra ( Figure 6A,B ). Martarega oriximinaensis can be easily recognized by (1) the presence of one or two groups of short bristles near the lateral margin of the mesotrochanter ( Figure 6C ), (2) the distinct acute shape of right clasper, slightly larger than left, never longer than wide, and (3) the more rounded shape of left clasper ( Figure 6F,G ).
