Cheramus parvulus .— Sakai, 2011: 370.

Spinicallianassa parvula .— Poore et al., 2019: 139, 143.

Material examined. Australia, WA, North West Shelf , 19° 04.4' S, 118° 47.35' E, 83 m, NTMAG Cr000783 (holotype female, 4.0 mm) .

Distribution. Northwest Australian Shelf ( Australia, WA); 83 m.

Remarks. The damaged holotype lacking maxilliped 3 and chelipeds is the only specimen. The long horizontal sharp rostrum, swollen eyestalks and oval propodus on pereopod 3 are consistent with Spinicallianassa . The telson, reillustrated here (fig. 53), is 1.2 times as wide as long, has spiniform setae in the anterior dorsal transverse row, a pair of dorsal spiniform setae more lateral and posterior, and irregular short spiniform setae on the posterior margin, not as excavate as illustrated by Sakai (1988). The three facial setae on the uropod are confirmed (fig. 53). The specimen is a female with gonopores on the coxae of pereopods 3 and female-like pleopods 1 and 2, not a male as stated by Sakai (1988, 1999). The species may be synonymous with S. spinicauda .
