Title

Frisia gen. nov., a new Cerviniinae Sars (Copepoda: Harpacticoida: Aegisthidae Giesbrecht) from Tierra del Fuego (Chile), with description of a new species

Abstract

A new species of Aegisthidae (Copepoda, Harpacticoida) is described from the upper subtidal of the western coast of the Isla Grande de Tierra del Fuego (Chile). Frisia magellanica gen. et sp. nov. is allocated into the subfamily Cerviniinae because of the comparatively short and divergent furcal rami. However, an assignment to any of the six known cerviniin genera is not possible, as Frisia magellanica gen. et sp. nov. does not share the respective autapomorphies of Cervinia, Cerviniella, Eucanuella, Expansicervinia, Hase, and Paracerviniella. Instead, the new species provides a number of deviations , e.g. a 5-segmented antennule in the female and the male, the presence of a peculiar, large and inflated seta on the fourth antennular segment, the reduction of 1 seta on the mandibular basis, and a remarkable elongation of both the female P5 exopod and the P6. These deviations are hypothesized as autapomorphies of F. magellanica gen. et sp. nov., justifying its allocation in a new genus Frisia gen. nov.
