Diagnosis. Breda bistriata differs from the other species of the genus by having an elongate carapace and a strong tranverse stripe of yellowish scales on the distal portion of the dorsal abdomen in both sexes (Fig. 57). The male is similar to that of Breda apicalis by the tibial apophysis distally dilated in the palp (Fig. 59), but differs from this species by having the embolus tip straight (Figs 37, 58).
