| Aricidea assimilis sensu Strelzov, 1973 | very long (up to ch. 6); often missing or regenerating (short) | from ch. 4; easily broken off, anterior pairs just about meeting in the middle becoming very long posteriorly, last 1-2 pairs extremely short | somewhat distally bidentate, with indistinct pubescence, often with short, thin arista arising from the convex side | |
| A. simplex | very short (not reaching past posterior margin of prostomium) | from ch.4; very short (extending half way to dorsal midline), last few about half that length | heavy, distally curved spines, not aristate | robust (wide) body, sometimes ventrum of anterior segments with pigmented horizontal lines |
| A. cf. ramosa | short, branched, with up to 5 branches | from ch. 4, anterior pairs just meeting at middle, getting longer posteriorly and then reducing in size again, the last pair short | slender, straight or curved, bearing elongate terminal arista | |
| A. antarctica | short, may appear bi-articulate | from ch. 4, all pairs similar in length, just about meeting in the middle | slender, gently some strongly bent, tapering to very fine arista | |
| A. cf. antennata | very long (up to ch. 5) | from ch. 4, not meeting at midline at the widest part of the body, reducing in size posteriorly, reaching the midline at the narrow part of the body | thickened gently curved chaetae with long thin arista | notopodial postchaetal lobes branched in some anterior segments |
| A. pisanoi | of median length, reaching to ch. 3 | from ch. 4, long digiform | absent | |
| Levinsenia acutibranchiata | absent | from ch. 8, branchiae with sharp tips | heavy spines, not aristate | |
