First record and establishment of Branchiomma coheni (Polychaeta: Sabellidae) in the Atlantic Ocean and review of non – indigenous species of the genus Keppel, Erica Tovar, Maria Ana Ruiz, Gregory Zootaxa 2015 4058 4 499 518 N6NZ Ehlers, 1901 Ehlers 1901 [151,601,1625,1651] Polychaeta Sabellidae Branchiomma Animalia Sabellida 9 508 Annelida species curtum  Materials examined and compared by Tovar-Hernández & Knight-Jones (2006)do not show significant morphological differences with Ehlers syntypesbecause juveniles of different species can look all similar. Shape and size of stylodes in juveniles of many species of  Branchiommachange in adult stages. Additionally, the original description and drawings by Ehlers (1901)emphasized important differences among the nominal species  B. curtumand specimens reported in from the Mexican Caribbean. The thoracic uncini has one row of teeth, covering 1/4 of the main fang length in  B. curtum( Ehlers 1901: plate 25, Fig. 13) versus three rows covering 1/2 of the main fang length in Caribbean material. Thus, the status of  B. curtumas NIS in the Mexican Caribbean, New Zealandand Cape Verdedemands a further morphological study using adult forms as well as molecular markers at juvenileadult stages.
