Description Description of the holotype: disc diameter 3,5 mm. Single complete arm about 5 times the disc diameter. Edge of the disc nnot sharp, without differentiated scales. Dorsal scales of very variable size. No rosette recognized, but some larger plates in the central area and along the interradial spaces. Radial shields length less than half the disc radius, separated by 4-5 scales, bredth half of length. Ventral disc scales smaller. Oral shields longer than wide, broadest near the distal end. Adoral shields with a distal lobe reaching the genital slit. Four oral papillae in a regular, continuous straight row; third papilla slightly elongates. Oral tentacle scale absent. Dorsal arm plates wide, proximally in contact, lateral sides rounded, distal and proximal sides straight. Three arm spines, tapering, not very flattened. Two large tentacle scales. Ventral arm plates pentagonal, distal edge straight or slightly concave, first few plates not contiguous. Colour uniformly white when dried (Tortonese, 1980). [details]

Adoral shields with a distal lobe reaching the genital slit. Four oral papillae in a regular, continuous straight row; third papilla slightly elongates. Oral tentacle scale absent. Dorsal arm plates wide, proximally in contact, lateral sides rounded, distal and proximal sides straight. Three arm spines, tapering, not very flattened. Two large tentacle scales. Ventral arm plates pentagonal, distal edge straight or slightly concave, first few plates not contiguous. Colour uniformly white when dried (Tortonese, 1980). [details]
