GENUS CORDESIA WARÉN & BOUCHET, 2009

Type species: Cordesia provannoides Warén & Bouchet, 2009 (by original designation).

Diagnosis: Males of this genus possess a cylindrical penis. Protoconch sealed with a calcareous plug and

views (M). L, the protoconch can be observed as having about 2.5 whorls; the first whorl is eroded and then its cancellate sculpture is not preserved. The whole radula is shown in O, where the box indicates the position of the detailed view in P. A–C, E, F–H and K are in the same scale (shown in between B, C and E). ct, central tooth; lt, lateral tooth; mt, marginal tooth; pr, protoconch; te, teleoconch.

with planktotrophic larval development traits. Two right pallial tentacles. Radula with long and slender marginal teeth that resemble those of Provanna . Cordesia species have planktotrophic development that could be observed by many larval shell whorls and a complex sculpture on protoconch. These deepsea gastropods are associated with chemosynthetic environments, such as cold seeps and organic falls.
