Type species
Macromysis gracilis Dana, 1852 , currently acknowledged in revised combination as Mysidium gracil e ( Dana, 1852).
Diagnosis
Compiled with the reservation that not every one of the following characters is known in Mysidium iliffei Băcescu, 1991 (see Discussion):
Anisomysini with eyes normal, eyestalks and cornea well developed. Antennular trunk terminally with the usual two flagella in both sexes, no accessory flagellum developed.Appendix masculina large, setose. Antennal scale lanceolate, without spines, but setose all around, with small terminal segment. Mandibles normal, palp three-segmented, cutting edges with well-developed pars incisiva, lacinia mobilis and pars molaris. Distal segment of maxillary palp with setae, but without denticles. Thoracopods essentially normal, endopods with 2- or three-segmented carpopropodus. All pleopods of females and pleopods 1–3, 5 of males are vestigial, setose, uniramous, unsegmented. Male pleopod 3 larger than pleopods 1–2, 5. Male pleopod 4 even longer, modified, with distinct sympod, unsegmented endopod and 3- or 4-segmented, slender exopod. Terminal two segments of exopod each bearing a large modified seta, remaining segments usually without setae, at most with one small seta on the basal segment. Uropods setose all around, without spines; exopods longer than endopods. Telson longer than broad, with entire or incised terminal margin; with spines and laminae on distal half.
Etymology
Derivation and gender of Mysidia and Mysidium not stated by Dana (1850, 1852). Neutral gender of Mysidium implicitly fixed by Czerniavsky (1887: 85) upon proposing the revised combination Mysidium gracile ( Dana, 1852) .
