Material examined: Parrachos de Maracajaú , Maxaranguape, 20.VI.2015, one specimen, 40 mm (body length), leg. T. Accioly ( GEEFAA 1321 ) ; Praia de Pirambúzios, Nísia Floresta, 13.II.2014, one specimen, 7 mm (body length), leg. T. Accioly ( GEEFAA 270 ), 13.III.2014, one specimen, 6 mm (body length), leg. T. Accioly ( GEEFAA 260 a), 03.IV.2014, one specimen, 10 mm (body length), leg. T. Accioly ( GEEFAA 265 a) .

Description: Elongated and cylindrical body. Black background coloration with the edges of the parapodia, presence of circular and opaque spots in turquoise, distributed all over the body. Cephalic shield very robust and elongated with the presence of developed eyes and a pair of ciliary tufts on each side of the mouth. In the distal body, there are two lobes, the left one being well developed and pointed, forming a prominent tail.

Geographic distribution: Bahamas, Belize, Bermuda, Cayman Islands, Colombia, Cuba, Honduras, Jamaica, Martinique, Mexico, Panama, Puerto Rico, USA, Brazil (Bahia, Rio Grande do Norte – present study) ( García et al., 2008).

Remarks: Ornelas-Gatdula et al. (2011) performed a phylogenetic analysis on specimens of Chelidonura from the Caribbean region and concluded that variations of different species belong to C. berolina . In addition, their analyses revealed a new species, C. normani , endemic from the Bahamas, very similar to C.berolina but differentiated genetically and by the morphology of the posterior end of the foot, being longer and thinner in C.berolina . García et al. (2008) recorded C. berolina for the first time in the South Atlantic Ocean, based on material from Bahia, northeastern Brazil.The present study confirms the presence of C. berolina from northeastern Brazil, being the first record from Rio Grande do Norte.
