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 ). 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 ).
