Comment: Garth (1960) has described a closely related species from Galapagos, P. darwini, that he considers its analogous in EP (comparison of both species made by F. Chace at US national Museum). McDermott (2014) has indicated that 'all specimens of P. faxoni and P. vanderhorsti were lost in the mail many years ago, during their return to the Smithsonian Institution after being on loan (Rafael Lemaitre, Curator of Crustacea, USNM, pers. comm. 2013' and that 'both P. faxoni and P. vanderhorsti, pending discovery of additional specimens, should be included in the new genus (Laminapinnixa)'.
Comment(s) on data
Komatsu & Takeda (2009) - Species of the genus live in mantle cavities of bivalve mollusks, in tubes or holes of annelid worms, holothurians, and hemichordates, and also freely in muddy or shelly bottoms (Sakai, 1976). It is well known that one of the Japanese species, P. rathbuni Sakai, 1934, sometimes forms big swams in shallow water (Sekiguchi, 1983).
Les types de P. faxoni sont apparement perdus, cf. Mcdermott (2014) - Unfortunately, all specimens of P. faxoni and P. vanderhorsti were lost in the mail many years ago, during their return to the Smithsonian Institution after being on
loan (Rafael Lemaitre, Curator of Crustacea, USNM, pers. comm. 2013).
Une sp. très proche, Laminapinnixa miamiensis vit dans les terriers d'un siponcle, with burrows of Sipunculus nudus Linnaeus, 1766 (cf. McDermott, 2014).
