Remarks

The worn shells from northeastern Brazil herein studied ( Fig. 21 G–H) are only the fifth/sixth records of I. carmelae from Brazil, even after the analysis of thousands of lots from several localities; all other shells were recorded from the Vitória-Trindade Chain ( Fernandes et al. 2013). The paucispiral protoconch of I. carmelae has one whorl of larval shell, scupltured with axial ribs and a spiral cord ( Rolán & Fernández-Garcés 1993; Fernandes et al. 2013), indicative of a short but existing planctonic stage. More records may be added to the present ones in the following years, both in the Caribbean and Brazil, instead of the current geographically isolated records (but see Discussion).

Geographical records

Cuba (type locality); Brazil: Maranhão, Rio Grande do Norte (this study), Vitória-Trindade Chain ( Fernandes et al. 2013).

Bathymetric distribution

5 m ( Rolán & Fernández-Garcés 1993) to 82–105 m ( Fernandes et al. 2013).
