Phalangipus australiensis Rathbun, 1918

( Fig. 6B–C )

Material examined. RV Hakuhō Maru KH-72-1 cruise, sta. 30, 3ƏƏ( CB 10.9×CL 12.0 mm – 12.5× 13.6 mm), NSMT-Cr 30723. — Sta. 32, 1 ovig. $ ( CB 13.2×CL13.0 mm), NSMT-Cr 30724; 1 $ (12.0× 11.8 mm), NSMTCr 30725.

Remarks. The present specimens ( Fig. 6B–C ) were identified as P. australiensis of the nine species of Phalangipus , because the G1 is short, stout and straight in distal two-thirds ( Griffin, 1973: fig. 8C–D), differing from the curved G1s of the congeners.

Distribution. Aru Islands, Sahul Shelf, northern and eastern Australia from Broome (Western Australia) to Port Stephens (New South Wales) ( Rathbun, 1918; Griffin, 1966b; Campbell and Stephenson, 1970; Griffin, 1973; Griffin and Tranter, 1986); 5–120 m depth.
