There are no distinct transverse ridges behind the level of the last spine of the antero-lateral borders. The first spine of this border is anteriorly truncated. The major diameter of the orbits is one-third the width of the inter-orbital space. The propodite of the last pair of legs bears one or two inconspicuous denticles near the far end of its posterior border. In the male abdomen the sixth segment is much broader than long and has curved and gently convergent sides.
The anterior male abdominal appendages are more or less straight, with the tip bluntly pointed. There is a thick fringe of hairs on the distal part of the outer margin, and a few short scattered hairs on the upper surface also.
