Phylladiorhynchus cf. pusillus ( Henderson, 1885) View in CoL
( Fig. 20 View FIGURE 20. A B, 22)
Galathea pusilla Henderson, 1885: 407 View in CoL [type locality: off New South Wales, Australia]; 1888: 121, pl. 12: figs. 1, 1a, b. Galathea integra Benedict, 1902: 248 View in CoL [type locality: off Honshu, Japan].
Galathea lenzi Rathbun, 1907: 49 View in CoL , pl. 3: fig 1 [type locality: Corral, Chile].
Phylladiorhynchus pusillus View in CoL .— Haig, 1973: 282.— Baba 1974: 381; 1991: 486–487, fig. 4e, f; 2005: 305 [synonymy].
Material examined. Norfolk Ridge: NIWA 28065, 1 female (8.7 mm), southern Norfolk Ridge, 33°23.41’S, 170°11.58’E, 469–526 m, TAN0308/126 #87, 31 May 2003.
Southeastern Australia: AM P17563, 2 males (4.9–5.5 mm), 1 female (4.7 mm), S and SW of Mount Cann, Gippsland, Victoria, Australia, 120–183 m; AM E6158, 1 male (6.9 mm), S of Cape Everard, Victoria, Australia, with rhizocephalan.
Colour in life. Carapace and abdomen transparent, pale yellow-orange; with orange-red marginal spines and rostrum. Chelipeds clear, diffuse pink-red; spines orange-red. Fingers crossed by white band. Walking legs with diffuse, clear orange-red banding.
Remarks. The single NORFANZ specimen agrees with several ‘large’ Australian and New Zealand specimens reported as P. pusillus by Haig (1973) and Baba (1991), respectively, in their straight or almost straight rather than distinctly convex rostral margins. Phylladiorhynchus pusillus sensu stricto bears convex rostral margins ( Baba 1991) and generally does not exceed about 5 mm carapace length. The rostral condition of these ‘aberrant’ specimens appears not to be an allometric artefact, being stable across a wide size range ( Fig. 22 View FIGURE 22 ). As presently understood, P. p u s i l l u s could be a composite taxon, so present specimens are only tentatively identified pending a review of Phylladiorhynchus by K. Schnabel (NIWA).
Distribution. Western Indian Ocean to eastern Australia, New Zealand, the Chesterfield Islands, to Japan, San Félix, and the Juan Fernández Islands; intertidal to 580 m ( Baba 2005).
