Head, thorax and abdomen predominantly dark brown above but with a prominent large cream patch on either side of the pronotum (Figure 2). Small lateral pale patches also on mesonotum, metanotum and tergites. Hind femora dark above, pale below. Hind tibiae predominantly cream, slightly darker on dorsal surface. Femora without spines. Fore and mid tibiae have four apical spines each (Figure 2). Foretibiae with 1 prolateral superior linear spine, 4 prolateral and 4 retrolateral inferior linear spines. Midtibiae with 2 prolateral and 2 retrolateral superior linear spines, 4 prolateral and 4 retrolateral inferior spines. Two rows of about 10 small, pale, fixed spines along distal three quarters of superior surface. Male — with simple, oblong subgenital plate bearing small, cylindrical styles on each rounded corner. Paraprocts are short, stout and tapering abruptly, directly rearwards. Cerci pale, slender, similar in length to paraprocts. Female — ovipositor long but less than length of hind femur, pale and stout at base but tapering rapidly, gently curved upwards, and grading to orange-brown at tip, with no serrations. Subgenital plate pale, simple triangle (Figure 2). Dimensions: Holotype: HD 5.6, BL 14.2, HFL 10.7, HFW 3.3, HTL 8.8, PL 2.9, PW 3.7.

Head, thorax and abdomen predominantly dark brown, nearly black at dorsal limits, lacking pale patches on thoracic and abdominal segments. Legs dark brown on dorsal surfaces grading laterally to yellow-brown. Abdominal sternites brown including male subgenital plate, but female subgenital plate yellow. Cerci and styles (of male) yellow-brown. Numerous discrete, pale spots on dark areas of legs and posterior-lateral of abdomen.

Foretibiae with 1 prolateral superior linear spine, 4 prolateral and 4 retrolateral inferior linear spines. Midtibiae with 2 prolateral and 3 retrolateral superior linear spines, 4 prolateral and 4 retrolateral inferior spines. Hind tibiae with 2 pale prolateral and retrolateral spines on inferior surface. Two rows of about 10 small or very small, fixed spines along distal three quarters of superior surface. Male — subgenital plate in ventral view oblong, blunt, slightly longer than wide.
