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.
