N Abstract: The terebrid gastropod Hastula hastata southeastern Brazil. The new record extends the known geographic range of the species ca. 1,167 km eastward from Vitória, Espírito Santo state. (Gmelin, 1791) is reported for the first time from Trindade Island, off

The Terebridae exhibit the most homogeneous shells Hastula hastata (Gmelin, 1791) is a common species in among the seven conoidean families (Bouchet and Rocroi the western Atlantic occurring from Florida, USA, to Rio de 2005). Geographically and ecologically, it is the most Janeiro, Brazil (Rios 2009; Rosenberg 2009). restricted family, occurring primarily on sand at shallow, subtidal depths, in the tropics and some subtropical regions (Bratcher and Cernohorsky 1987). There are 411 In July, 2013, one live specimen was collected during extant species in 17 genera according to the most recent depthscuba (Figure dive at 1).

Perhaps this species often occur in or just below the “surf” zone on was why only one specimen was found. The collection was sloping sand beaches. Hastula is characterized by a made during the austral winter, but the water temperature smooth, shiny shell, with axial sculpture of crenulations or slender ribs below the suture. There is no spiral sculpture about 24°C on average. except for a subsutural groove or row of punctations (Kohn at TrindadePermits were Island granted remains by Environmental high throughout Agency the of year, the 1998).

This wide distribution suggests a possible for numerous axial ribs (24 on the body whorl) that extend lecithotrophic larval stage that allows for long permanence in the plankton (Miller 1975). Lecithotropihic larvae have below the suture. The columella is smooth, without plicae, from suture to suture.
