Perinereis ‘pale_NTM W22527’ Glasby

( Fig. 5 B, C)

Material examined. NTM: W22527 (1), between Casuarina Beach and Palfrey Island, 14°40.92'S 145°26.83'E, coll. C. Glasby, 6 Apr 2008.

Diagnosis. Member of Perinereis nuntia group having 6 small paragnaths in Areas VII–VIII arranged in single line, and relatively few paragnaths on maxillary ring ( Fig. 5 B, C).

Remarks. The number of paragnaths in Areas VII-VIII is less than that for any other species in the P. nuntia species group ( Wilson & Glasby, 1993). The species will be formally described provided further specimens are collected.

Habitat. Back reef in coarse coral rubble, 1 m.
