P. Bouchet et Gj. Vermeij, 2 NEW DEEP-WATER PSEUDOLIVIDAE (NEOGASTROPODA) FROM THE SOUTH-WEST PACIFIC, The Nautilus (Philadelphia), 111(2), 1998, pp. 47-52
The new genus Fusulculus, conchologically most similar to Benthobia Da
ll, 1889 and Zemira H. & A. Adams, 1853, is erected for axially sculpt
ured species of Pseudolividae with shouldered whorls and obsolete labr
al tooth; the columellar and parietal callus is of very limited extent
, and a parietal rib at the adapical end of the inner lip is absent. T
wo new species, Fusulculus crenatus (type of genus) and F. albus are d
escribed from bathyal (400-800 m) hard bottoms at tropical and subtrop
ical latitudes in the southwest Pacific. No post-Paleocene species of
Pseudolividae are known from the tropical Indo-Pacific; the habitat of
Fusulculus is bathymetrically transitional between those of Benthobia
, from abyssal depths, and the various genera from subtidal waters in
southern Australia, South Africa and Angola.
