Nereis (Ceratonereis) marmorata Horst, 1924: 177 View in CoL –178, pl. 34, figs 13–16. Composetia marmorata View in CoL .— Pamungkas & Glasby 2015: 8 –9, fig. 3c, d.

Material examined. NTM: W22530-T (1), Big Vicky Reef, NW of Palfrey Island, 14°'S 145°'E, coll. K. Mills, 12 Apr 2008; W22615-T (1), Day Reef, 14°28.27'S 145°37.78'E, coll. M. Blazewicz-Paskowycz, 13 Feb 2009; W22797-T (1), Macs Reef, 14°39.49'S 145°29.48'E, coll. K. Mills & S. Smith, 25 Feb 2009.

Comparative material examined. NTM: W23811 (1), Salawati, Raja Ampat, Indonesia. Nereis (Ceratonereis) marmorata ZMA VPol 0 869 (17 syntypes) and RMNH 1352 (5 syntypes), R/V Siboga Stn 172, Gisser anchorage, between this island and Seram-Laut, Maluku, Indonesia, 3° 53.1534’S 130°51.934’E, coll. 26 Aug 1899.

Diagnosis. Composetia species having distinctive marmorated-stripes on antero-dorsal body and prostomium ( Fig. 1 View FIGURE 1. A G); paragnaths conical, arranged as follows (n = 1): Areas I: 1; II: 8–9 in cluster of two curved rows; III: 3; IV: 10–12 in triangular cluster ( Figs 1 View FIGURE 1. A H, 2A).

Remarks. The markings are as described by Horst (1924: 177) for Nereis (Ceratonereis) marmorata ; pigmentation fades in preserved specimens ( Figs 1 View FIGURE 1. A H, 2A). Examination of paragnath numbers in the syntypes confirmed the identification; the number in Area III appears to be highly variable, from 3 reported here to 4–18 in the syntype material as decribed by Horst (1924). This species was not collected in the August 2013 survey.

Habitat. Lagoon to reef slope, 3– 30 m.

Type locality. Between Gisser and Seram-Laut, Maluku, Indonesia.

Distribution. Indonesia. First record for Lizard Island and Australia.
