MATERIAL EXAMINED. — Guadeloupe. Caribbean Sea, Marina, Rivière Sens, in Pyura momus (Savigny, 1816) (probably erroneous identification, see Remarks), date unknown, 1 ♂ pocl. 2.2 mm (MNHN-Na 8231). — Rivière Sens, in Microcosmus exasperatus Heller, 1878 , date unknown, 1 ovigerous ♀ pocl. 4.1 mm (MNHN-Na 8227).

REMARKS

The species has been recorded from Martinique and Antigua Island in the Caribbean and from the Mauritanian coast in the East Atlantic. This is the first record of the species for Guadeloupe.

The host Pyura momus is a synonym of Herdmania momus Savigny, 1816 . This species is restricted to the Indo-West Pacific. According to P. Kott (pers. comm. A. J. Bruce) the ascidian species from Guadeloupe, which is figured by Monniot (1983), is different from H. momus s.s. The species is clearly a species of Herdmania and not of Pyura .
