The cephalothorax is moderately high, narrower than in the allied species, the quadrangle wider behind, the anterior row much curved, the S. E. small and well separated from the M.E., the eyes of second row almost twice as near to the lateral as to the dorsal. The posterior metatarsi are more slender than usual, and spined only at tip.
