Disk circular (dd = 1.30 to 6.90 mm). Covered by imbricating scales of different sizes, largest between radial shields and on interradial margin of disk (Fig. 12a). Radial shields narrow, long, broadly separated, distal end slightly broader, distinct from remaining disk because of their white coloration (Fig. 12a). Numerous olive-green patches on the dorsal and ventral sides of the disk (Fig. 12a). Ventral interradius with scales similar to dorsal disk surface (Fig. 12b). Bursal slits broad and elongated. Oral shields large, diamond-shaped, laterally broadened, some with a dark spot on distal margin. Two spatulate oral papillae (Fig. 12c), borders slightly denteate, on each margin of jaw, the outer one slightly longer. A cluster of dental papillae on apex of jaw (Fig. 12c). Dorsal arm plate slightly wider than long, distal border slightly wider than anterior border (Fig. 12d). Ventral arm plate longer than wide, pentagonal, posterior margin concave (Fig. 12e). Two tentacle scales (Fig. 12b, e), outer smaller and inner longer, flattened and overreaching median ventral plane of arm. Tentacle pore large. Four to
arm spines, ventral one longest and slightly curved (Fig. 12d, e). Remaining spines decrease in size ventralwards, with small denticles at apex. Two close brown stripes on lateral arm plate, and a lighter median band on the dorsal arm plate (Fig. 12a, d). Ventral surface sometimes with two brown stripes close to insertion of spines.
A dorsal view, detail of the radial shields B ventral view, detail of the tentacle scale C jaw D dorsal view of the arms E ventral view of the arms. Scale bar = 1 mm.
