Perinereis nuntia species group Wilson & Glasby, 1993: 259.

Material examined. AM: W.44302-T, MI QLD 2391 (1); W.44311-T, MI QLD 2391 (5). NTM: W22580-T (1), Casuarina Beach , 14°40.8'S 145°26.84'E, coll. C. Glasby, 12 Apr 2008.

Remarks. The present specimens are typical of the species group in lacking pigmentation ( Fig. 4 F). They do not correspond to any known species in the group ( Wilson & Glasby 1993; Glasby & Hsieh 2006; Yousefi et al. 2011). This material belongs to the subgroup of Perineris nuntia species group that lack heterogomph spinigers in the neuropodia of anterior chaetigers; the heterogomph spinigers first appear from chaetigers 18–42 and, in small specimens, are absent altogether.

Habitat. In sand around beach rock; intertidal.

Distribution. Indo-West Pacific, Red Sea.
