Key to genera and subgenera in the Janirellidae 1. Cephalon with true rostrum, or pseudorostrum derived from frons/clypeus; front margin between antennulae> 2 times width of antennula base; posterior margin of pleotelson projecting between uropods; uropods normally> 0.2 length of pleotelson................................................................................................... 2 - Cephalon front without rostrum or pseudorostrum, front margin between antennulae equal to width of antennula base; posterior margin of pleotelson an even convex curve between uropods; uropods> 0.7 length of pleotelson ................................................................................................................... Dactylostylis 2. Cephalon with true rostrum, simple or complex; body generally fusiforme, with lateral spines (for exceptions see Discussion).................................................................................................................... 3 Janirella - Cephalon with distinctive pseudorostrum; body flattened, body margins parallel, pereonites laterally truncate without spines ............................................................................................................. Triaina gen. nov . 3. Pleotelson with several lateral projections; lateral projections of pereonites setiferous.............
