Eye tubercle low, median only slightly depressed, unarmed except for two or three small granules above each eye. First to fourth areas, hind margin of scute and free tergites with a row of small granulations. Lateral ridges of scute also with a row of small granules.
  • Venter Surface of first coxa with a row of coarse tubercles, and two enlarged teeth, one of which of bizarre contour, on the front edge. Second and third coxae with small tubercles, tubercles mostly confined to proximal region; a row of small humps present on anterior and posterior edges of the third. Fourth smooth, some coarse teeth on the retrolateral edge. Spiracles concealed. Genital plate and free sternites smooth, only hairy.
