portion ; tibiae nearly straight; tarsi tapering apically ; claw large

 of the different parts of the hind leg are: Coxa, 60 /*; trochanter 

 and femur, 87 /*; tibia, 72 /*; tarsus, 66 ^ claw, 21 ^ Small 

 pores and fine spiny hairs are sparsely distributed over the 

 dorsum. Anal cleft not deep. Anal plates (Plate 1, fig. 1, d)
