Remarks. According to Kavanagh et al. (2015), the freely articulating posterior pereonites, pleonite 1 and pleotelson observed in Ischnomesus is a condition presumed to be plesiomorphic, with other genera showing various degrees of fusion of the pereonites (e.g. pereonites 5–7, pleonite and pleotelson fused together in genus Haplomesus ; Kavanagh & Wilson 2007). Uniarticulate uropods have been described by Merrin & Poore (2003) for Ischnomesus justi , so the biarticulate uropods may not be a diagnostic character for the genus, although all other species, described with this structure, have biarticulate uropods.
