Taxonomic remark From WoRMS (based on Huys, 2009): Philippi (1843: 64) proposed this genus for a new species Idomene forficata based on a single individual. The original description is fragmentary and insufficient for unequivocal identification, hence most authors have invariably referred to Sars’s (1906a: 134) detailed redescription and used his diagnosis of the genus as the major standard of reference for adding subsequent species, either newly described or reassigned from other genera regarded as junior synonyms of Idomene. This shift in attention had the unfortunate consequence that noone either scrutinized the real identity of Philippi’s (1843) type species or confirmed its conspecificity with what Sars (1906a) had identified as I. forficata. In spite of their poor quality, Philippi’s (1843) illustrations provide sufficiently compelling evidence that I. forficata is not a harpacticoid but rather a poecilostome cyclopoid. The 7-segmented antennule with four setae on the basal segment, the 3-segmented antennary endopod, the mandibular gnathobase with distinct blades (his Fig. 4f, labelled “ein Kaufuss?”), and the laterally located, uniramous fifth legs (with 2 outer margin spines, 1 apical seta and 1 inner spine) not only unequivocally exclude I. forficata from the oligoarthran Harpacticoida but also identify it as a member of the family Clausidiidae in the Cyclopoida. The armature pattern and shape of the maxilliped is another line of evidence supporting such assignment. It is conceivable that Idomene Philippi, 1843 is the senior synonym of either Hemicyclops Boeck, 1873 or Hersiliodes Canu, 1888. It is here considered a genus incertae sedis in the Clausidiidae. Since Philippi’s type material no longer exists a neotype can unfortunaly not be designated. [details]
