Iboyella, a new genus of epacteriscid copepod (Copepoda: Calanoida: Epacteriscidae) from Cuba

Abstract

A new genus of Epacteriscidae is described from a single female of a new species, Iboyella cubensis gen. et sp. nov., collected in an anchialine cave on Cuba. This is the second genus in the family described from Cuba. The new genus belongs in the subfamily Epacteriscinae and is distinguished from related genera by a mosaic of setation characters relating both to the mouthparts and to swimming legs 1 to 5. The combination of the lack of an inner seta on the first exopodal segment of the female fifth leg with the retention of a single seta on the mandibular basis is shared only with Gloinella. The new genus has a much reduced rostrum compared with that of Gloinella, and there are differences in maxillulary and maxillipedal setation.
