| Summary: | Key to the Southern Ocean species of Macrostylis 1 Pleotelson rounded laterally. 4 - Pleotelson not rounded laterally. 2 2 Pleotelson laterally straight, with plumose setae. M. hirsuticaudis - Pleotelson not laterally straight, without plumose setae. 3 3 Cephalon quadrate, pleotelson with lateral indentation. M. bifurcatus - Cephalon triangular, pleotelson slightly produced. M. spiniceps 4 Pereonites 5–7 and pleotelson dorsally setulose. M. setulosa - Pereonites 5–7 and pleotelson not dorsally setulose. 5 5 Pereonite 7 and pleotelson with dorsal spine-like setae. M. sarsi - Pereonite 7 and pleotelson without dorsal spine-like setae. 6 6 Pereonites 1–7 subequal, 5–7 with postero-lateral spines. M. cerritus sp. nov. - Anterior pereonites wider than posterior pereonites. 7 7 Distinct postero-lateral spines on pereonites 4–7, cephalon anterior edge straight. M. vinogradovae - Small postero-lateral spines on pereonites 4–7, cephalon anterior edge slightly rounded.
