Babelomurex santacruzensis Kosuge, 1980 (Fig. 7F, G)

Latiaxis santacruzensis Emerson & D’Attilio, 1970: 272, 273, pl. 40, figs 1-4.

TYPE MATERIAL. — Holotype (AMNH 155901). — Paratypes (AMNH 155902; LACM 1234 [1 dry]) 88- 134 m, off Isla Santa Fe (Barrington), Islas Galapagos (0°43’S, 90°01’W, RV Velero III, 26.I.1938), and in the collections De Roy and D’Attilio (Emerson & D’Attilio 1970: 273) .

TYPE LOCALITY. — Galapagos Islands, Ecuador.

MATERIAL EXAMINED. — Th e type material and: BENTHAUS, stn DW 1904, Banc NE of Rapa, 27°26.5’S, 144°03.4’W, 600-900 m, 1 dd (Fig. 7F, G).

Galapagos Islands, imprecise collecting data, 2 lv (dealer source: MO).

DISTRIBUTION. — Previously considered endemic to the Galapagos Islands (Emerson & D’Attilio 1970; Keen 1971). Range extension to Austral Islands in the Indo-Pacific ecoregion, one empty shell in 600- 900 m.

REMARKS

The single shell collected is worn, partly broken and lacks the tip. It is however perfectly concordant with the type material. Th e paratype AMNH 155902 and one specimen in MO coll., have usable protoconchs of 2.5+ and 2.6 whorls, respectively, which allow inferring a planktotrophic development for this species.
