Material examined

Syntype ANSP 71081 of Fustiaria stenoschiza ; IBUFRJ 10579, sta C22f, 8 dd; IBUFRJ 10587, sta C62, 1 lv, 2 dd; IBUFRJ 14248, sta 42, 3 dd.

Distribution

USA: Florida (Henderson 1920; Abbott 1974); Caribbean Sea: West Indies (Pilsbry & Sharp 1897); Porto Rico; Barbados (Henderson 1920); Brazil: Espírito Santo (this study). Living 96 m (present paper), shells 80 to 110 m.

Remarks

This species was reported from Indonesia (Boissevain 1906) and Australia (Lamprell & Healy 1998). Scarabino (1995) consider specimens identified by Boissevain (1906) as D. stenoschizum to represent F. nipponica (Yokoyama, 1922) . Since the F. stenoschiza records from Australia in Lamprell and Healy (1998) were based on Boissevain (1906), their records must also be attributed to F. nipponica ; the distribution of F. stenoschiza is, therefore, restrited to the western Atlantic and the Caribbean Sea.

Fustiaria stenoschiza differs from F. liodon by the long and regular slit ( Figs. 54 and 56 ) and more rapidly tapering.
