Description
Front straight and laminar. No transverse markings on the post-frontal region. Last segment of male abdomen triangular.

The carapace is much more elongate, its length being seven eighths of its breadth, it sides are very markedly convergent posteriorly, and there are no transverse markings on the post frontal region. The front is nearly three fourths the greatest breadth of the carapace, and its free edge is decidedly laminar and nearly straight. The orbits or oblique; their major diameter is less than a third the breadth of the front and the inner angle of their lower border is not denticulate. The fingers of the chelae, though their tips are spooned, are not very blunt, the dactylus is much longer than the upper border of the palm. Except perhaps in the last pair of legs, the meropodites are narrower, their greatest breadth being decidedly less than half their length. In the male abdomen the terminal segment has a somewhat three lobed appearance.
