This species is distinguished by the antero-lateral borders being distinctly continued beneath the orbits to the angles of the buccal cavern. The carapace is two-third as long as broad, with numerous short, transverse rows of bead-like granules on its anterior half. These are more scattered on the hinder regions, but are distinct on the posterior borders and between the four antero-lateral teeth.
The anterior male abdominal appendages have their sides with backward projecting spinules. Near the tip are numerous barbed hairs. The appendages show a marked resemblance to those of Xantho (Lophoxanthus) scaberrimus baccalipes
