Abdomen brown to black; subgenital plate elongated upward, 2.2 times longer than cerci ( Table 1 ), indentation 2 times deeper than broad, indentation edge little or more concave; styles almost nil. Cerci not reaching half of the subgenital plate, rather thick at the base, abruptly thinned, curved laterally and internally towards the apical third, the apex ending in fine points and cross ( Fig. 3c ) or almost touching ( Fig. 4b ). Fore and mid legs long, reddish brown to black.
