Distribution

West of Leander Point and NE of Rowley Shoals, Western Australia; also Christmas Island in the eastern Indian Ocean. Elsewhere, the species is widespread on the continental slope in the tropical Indo-west Pacific, depth range 395–1880 m. 

Features

Dorsal fin 6; Anal fin 4; Pectoral fin 14-16; Vertebrae 16-18. Cephalic lateral line scale counts: preopercular 2-4; subopercular 4-6; dorsolateral branch of subopercular 4-6; supraorbital 7-10.

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.

Colour

Body pale with black tips on pelvic fins.

Etymology

The specific name is from the Greek mikros (= small) and pous (= foot) in reference to the minute pelvic fins of this species.
