Diameter of the disc (d.d.) = very small to 2 mm.

Dorsal disc scales distinct, central ones a little larger than the rest. Radial shields large, half the disc radius in length, twice as long as wide, contiguous. Ventral disc scales smaller, imbricate. Oral papillae three on each side of the jaw – one infradental and two lateral papillae, the distal papilla operculiform, twice as broad as middle one – together closing the oral slit. Adoral shields meeting in front of the oral shields. Dorsal arm plates wider than long, distal margin convex. Arm spines three, as long as the segment. Two tentacle scales.
