PHYLLADIORHYNCHUS PUSILLUS ( HENDERSON, 1885)

Type locality: South Pacific Ocean, off New South Wales, Challenger Expedition sta. 163; 220 m (120 fathoms) .

Known range: Eastern Indian Ocean, Japan, New Caledonia, New Zealand and Australia, intertidal to 310 m ( Poore, 2004); possibly eastern Pacific ( Baba, 1991; see below).

Occurrence at vents or seeps: Kermadec Ridge ( Clark & O’Shea, 2001).

Material: See Baba (1991: 486) for material and additional references to western Pacific localities.

Remarks: The genus Phylladiorhynchus currently includes four species, all from the Indian Ocean and/or Indo-West Pacific, and possibly one eastern Pacific species, although the latter might be synonymous with P. pusillus . If so, it would extend the range of P. pusillus significantly ( Baba, 1991). Phylladiorhynchus pusillus , originally described by Henderson (1885: 407) as Galathea pusilla , was transferred to Phylladiorhynchus by Baba (1969; see also Baba, 1991), and the species has been the source of some taxonomic confusion (discussed in Baba, 1991). The only record associated with vents or seeps is the listing by Clark & O’Shea (2001) from the Kermadec Ridge system.
