Gastroptychus spinirostris Ahyong and Poore, 2004: 9 –11, fig. 1, Uroptychus spinirostris .— Baba et al., 2008: 43, fig 1H.

Material examined. 1 female (cl 28 mm), 1 male (cl 10 mm), Western Australia, off the Kimberley plateau (13°15.9'S, 123°22.45'E – 13°16.35'S, 123°21.4'E), 390–394 m, 0 7 Jul 2007 (stn SS05/2007 180), CSIRO acquisition number 0 39, NMV J55996 View Materials .

Colour. Body and appendages pale pink. Spines on body pink-red, and spines on appendages orange with white tips.

Distribution. North-western and north-eastern Australia, 364– 394 m.

Remarks. The large female collected here is more than twice the size of the original material described from Queensland, and we observed variation in spination and setation compared to the holotype. The large female from north-western Australia has more numerous spines on the carapace, rostrum and sternum than the Queensland holotype. Our large female has three pairs of rostral spines compared with the holotype which has only 2 pairs of spines on the rostrum. While the holotype lacks setae, our female has rows of setae on the dorsal spines. The smaller male collected agrees very well with the Queensland material and thus we believe these differences are allometric.
