Identified only from Brazilian northeastern littoral, for the Rio Grande do Norte and Paraíba States. Etymology: The species identify is immediately after the companion of the initially writer, André Vidal, who assisted in the collection of material. Remarks: Associates of Euclymene vidali sp. nov. differ from members of E.
aucklandica Augener, 1923, in that the latter has 21 chaetigers, cephalic plate with crenulated posterior edge, uncini with 4–5 tooth on the rostrum, and midventral cirrus two moments for a longer period than other anal cirri. Users of E.

Customers of other species of Euclymene differ from E. vidali sp. nov. in obtaining 2–4 pre-pygidial achaetigerous segments, and the amount of chaetigers ( Desk II).
