Parathyone incurva Cherbonnier, 1988: 206 , fig 89

Parathyone incurvata ; Massin, 1993: 257 (lapsus calami) Ekmathyone incurvata ; Massin, 1993: 257 (lapsus calami) Material examined. Non-type material: IE-2007-774 (3 specimens, sampled North of Cape Saint André) ; IE- 2007-776 (10 specimens, sampled in South of Cape Saint Sébastien) ; IE-2007-787 (7 specimens, sampled in front of Nazendry Bay ) ; IE-2007-788 (1 specimen, sampled between Majunga and Cape Saint André) .

Remarks. Massin (1993) noted that Parathyone Cherbonnier, 1988 , is preoccupied and proposed Ekmanothyone Massin, 1993 as replacement name.

The specimens before us match perfectly with Cherbonnier’s (1988) description of P. incurva , and come from roughly the same area (Banc de Pracel) and depths (65m).
