Cercus straight with apical region slightly curved inwards, blunt apex and numerous small rounded socket setae ( Fig. 7H–J). Subgenital plate antero-medially slightly rounded, posteriorly narrowing sharply and remaining straight to the apex ( Fig. 7I). Subgenital plate with apex bifurcated, the space between the base of stylus narrow and rounded ( Fig. 7I). Subgenital plate slightly curved in lateral view ( Fig. 7J). Stylus long, curved, separated in base with apex curving laterally until it touches apex of the other stylus in dorsal view; curved upwards in lateral view, apex broad and blunt ( Fig. 7H–J). Stylus 1.3X longer than cercus.   FIGURE 7.  Phlugiola igarape  sp. nov.(holotype male).
