363-368, figs. 1-4 [neotype designation].

Type locality: Suriname ( Thyonidium occidentale ) and Bahia, Brazil ( Euthyonidiella occidentalis ).

Type material: Neotype – MZUSP 1139 : 80 mm long, Itapuã beach (12°57′S, 38°21′W), Salvador, Bahia, Brazil, intertidal, 12.i.2014.

Distribution: U.S.A. (Florida), Caribbean Sea ( Antigua, Aruba, Barbados, Puerto Rico, Trinidad and Tobago), Suriname and Brazil (Paraíba to Rio de Janeiro).

Remarks: In a taxonomic review of the dendrochirotids, Martins & Souto (2015) considered the taxon Phyllophorus occidentalis as more properly fitting the diagnosis of the genus Euthyonidiella , proposing the reassignment of the species. Concurrently, Euthyonidiella dentata Cherbonnier, 1961 was recognized as a junior synonym of E. occidentalis .
