Diagnosis (see also ‘Discussion’). Mysinae with antennal scale setose all around, scale in most species with small apical segment; carpopropodus of the thoracic endopod 6 with 3–26 segments; well-developed oostegites on thoracopods 7, 8, and rudimentary oostegite on thoracopod 6; all pleopods of females and pleopods 1, 2 of males rudimentary; male pleopod 3 mostly biramous, but uniramous, vestigial in Kainommatomysis, if biramous then with 1- to 15-segmented endopod and 2- to 16-segmented exopod; male pleopod 4 biramous, its endopod 1- to 14- segmented, its exopod 3- to 29-segmented, terminally with modified seta(e); male pleopod 5 shorter, biramous or uniramous; statoliths (as far as known) composed of fluorite; telson variable, mostly with apical cleft, this cleft (if present) lined by spine-like laminae, telson of several genera with a pair of medio-apical plumose setae emerging from the cleft.
