Disk almost globe-shaped, trapezoidal in outline with a flattened ventral surface. Illicial cavity very large. Lower jaw projecting relative to upper jaw. Dorsal surface of rostrum broad, flat with a slightly concave anterior margin and no enlarged median spine. Gill rakers as triangular plates with tiny teeth at distal angle.

Fins weak, pelvic fins extremely small. Tail relatively short and slender. Esca with paired and rounded ventral lobes, and a broad, relatively low dorsal lobe. Skin translucent, flabby, almost velvety - covered in small tubercles with slender spines.
