Prosoma yellowish, appendages slightly darker, with a pair of setae on ocular area. Without eyes. Median groove invisible, cervical grooves and radial furrow distinct, pale brown. Clypeus 0.13 high, slightly sloped anteriorly. Chelicera ( Fig. 64C) dark yellow, with six promarginal teeth, the distal one largest and five small retromarginal teeth.
