Diagnosis. Males of Nungara niveomaculata (Mello-Leitão) comb. nov. resemble those of Nungara anama sp. nov. by the palp with a C-shaped tegular groove (Figs. 28, 34, 50, 56) (longitudinal in N. gaturama sp. nov. see Fig. 39). They are distinguished from all other species of the genus by the embolus, arising from tegulum at 3 o’clock position (Figs. 50, 56) (2 o’clock in N. anama sp. nov., 6 o’clock in N. gaturama sp. nov. see Figs. 28, 39). The females are distinguished from those of the remaining species of the genus by the epigyne with median septum subtriangular, widest anteriorly (Figs. 52, 58) (oval in N. anama sp.nov., oblong in N. gaturama sp. nov. see Figs. 30, 41).
