Namalycastis senegalensis (Saint-Joseph, 1901) Fig. 7

Type locality.

Marsassoun, Senegal (13°59'N, 16°43'W; estimated geolocation).

Material examined.

Caranguejos Island, 02°49'33.6"S, 44°28'51.1"W: one specimen, incomplete, 22 October 2010 (NPM-Pol 105).

Distribution.

Atlantic Ocean: Senegal, Nigeria, Congo, Suriname, Brazil (states of Pará and Maranhão, see Suppl. material 1).

Remarks.

First record for Maranhão. Complete specimens were not found in this study; however, the features of the anterior body are very similar to the re-description of Glasby (1999). The presence of thick cuticle covering the eyes, supra neuro acicular sesquigomph spinigers in the parapodia of chaetiger 10, with a 1.4 × length of collar or more boss, and distally smooth falciger blades supports the identification of the species. Previous Brazilian records include the Amazon coast, the estuarine beaches of Marajó Island in the mouth of the Amazon River ( Glasby 1999), and the delta of the Amazon River (one specimen, ZHM PE405) ( Glasby 1999). This species is known to live in brackish water and freshwater environments such as mangroves, creeks, and marshes ( Glasby 1999).
