description: Key to species of Piromis Kinberg, 1867, emended
1 Tunic with abundant sand grains; individual papillae inconspicuous............................................. 2
- Tunic with few sediment grains, body wall mostly uncovered.................................................. 12
2(1) Sediment grains completely covering the body, partially immersed in the tunic, giving a rough surface, at least over anterior chaetigers............................................................................................ 3
- Sediment grains concentrated on dorsal and lateral surfaces, very few or none ventrally; neurohooks with distal article mostly unidentate, posterior neurochaetae with distal piece as long as 1/3–1/2 of total chaetal length...................................................................................... P. kisemboanus (Augener, 1918) n. comb., (partim)
3(2) Anterior chaetigers with notopodial lobes, sometimes eroded or reduced......................................... 4
- Anterior chaetigers without notopodial lobes............................................................... 9
4(3) Anterior chaetigers with dorsal tubercles.................................................. P. w e b s te r i Day, 1973
- Anterior chaetigers without dorsal tubercles................................................................. 5
5(4) Neuropodial hooks start in chaetiger 4 or 5 (markedly shorter than those present in preceding chaetigers)................ 6
- Neuropodial hooks start in chaetiger 6.................................................................... 7
6(5) Median and posterior chaetigers with neurospines with few long articles, distal article longest, entire.................................................................................................. P. e r u c a (Claparède, 1869)
- Median and posterior chaetigers with neurospines with many medium-sized articles, continued almost to the tip. P. s u n i n. sp.
7(5) Most sediment particles adhered through its widest area....................................................... 8
- Most sediment particles adhered through its narrowest area (look loosely adhered to the tunic); notopodia 2–8 rough, not form- ing conical lobes........................................................................... P. wehei n. sp.
8(7) Larger notopodial papillae about 1/4–1/5 as long as notochaetae; neurochaetal terminal article medially widened, bidentate.................................................................................. P. arenosus Kinberg, 1867
- Larger notopodial papillae about 1/2–1/3 as long as notochaetae; neurochaetal terminal articles cylindrical, tapering, mostly unidentate................................................... P. kisemboanus (Augener, 1918) n. comb. (partim)
9(3) Anterior chaetigers with fine sediment grains, often with dorsal tubercles............ P. capulata (Moore, 1909) n. comb.
- Anterior chaetigers with larger sediment grains, without dorsal lobes............................................ 10
10(9) First chaetiger with one pair of ventrolateral tubercles.................................... P. robertsi (Hartman, 1951)
- First chaetiger without ventrolateral tubercles............................................................. 11
11(10) Neuropodial hooks from median chaetigers with articles twice as long as wide throughout most of its length................................................................................................. Piromis fauchaldi n. sp.
- Neuropodial hooks from median chaetigers with articles barely longer than wide........................ P. vossae n. sp.
12(1) Median notopodia with about ten chaetae per bundle, as thick as, or slightly thicker than neurochaetae; neurohooks with distal article falcate, tapering................................................................... P. brisegnoi n. sp.
- Median notopodia with 6–7 chaetae per bundle, about as thick as neurochaetae; neurohooks with distal article straight, of about the same width..................................................................... Piromis amoureuxi n. sp.
