(1) Lucicutia Giesbrecht & Schmeil, 1898
Rem.: Hülsemann (1966) investigates the genus Lucicutia, giving specifications on the synonymies and the distribution of numerous species. The author brings to mind that the genus Isochaeta (Giesbrecht, 1889; Rose, 1933; Brodsky, 1950) was put in synonymy by Grice (1963). The family Lucicutiidae considered originally as a subfamily of the Centropagidae (Leuckartiinae de Giesbrecht 1892) has been created by Sars (1902). Andronov (1974) regards this family as relatively primitive, close to the Heterorhabdidae, Metridinidae, Augaptilidae and Arietellidae (Augaptiloidea).
Type: Leuckartia flavicornis Claus,1863. Total: 43 spp. + 1 unnamed.

Diagnosis after Bradford-Grieve (1999 b, p.92). Female :
- Body slender. Prosome oval.
- Head and pedigerous segment 1 separated, pedigerous segments 4 and 5 fused.
- Posterolateral corners rounded.
- Head rounded anteriorly, sometimes with anterolateral horns.
- Rostral filaments slender.
- Urosome elongate, 4-segmented.
- Caudal rami symmetrical, relatively long, with 7 setae.
- A1 symmetrical, 25-segmented.
A2 basis with 1-2 outer edge setae; exopod and endopod separated from basis; endopod 2-segmented, segment 1 with 2 setae at about midlength, segment 2 with 7 inner setae medially and 6 or 7 setae terminally; exopod 8-segmented.
- Md blade with 9 sharp teeth; endopod 2-segmented, segment 1 with 4 setae, segment 2 with 8 setae terminally; exopod segments 1-4 with 1 seta each, segment 5 carrying 2 setae.
- Mx1 inner lobe 1 (= praecoxal arthrite) with 13 spines and setae; inner lobes 2 and 3 with 3 setae each; basipod 2 with 4 setae; endopod 1-segmented, with 4+5 setae; exopod large, with 11 setae; outer lobe 1 with 5-6 setae.
- Mx2 lobes 1-5 with 3-4, 3, 3, 3, 3 setae, one of the setae on lobe 5 stouter than the other two, spinulose; endopod with 7 setae.
- Mxp basipod 1 (= coxa) with 3-5 setae; basipod 2 (= basis) with patches of setules or spinules and 3 setae medially; endopod 6-segmented, segment 1 almost fully incorporated into basipod 2 with 2 setae; segments 2-5 with 2 setae each, segment 6 with 4 setae the outermost 3 of which are reduced.
- Swimming legs 1-4 distinctly 3-segmented, endopod segments of P1 and P5 2-3-segmented, inner distal seta on basis of P1 inserted on a conical projection.
- P5 symmetrical, similar to other swimming legs; the inner edge seta on exopod segment 2 is modified into a long slender spine articulated with its segment.

Male :
- Body similar to female.
- Urosome 5-segmented.
- Left A1 geniculate, 21-segmented.
- Mouthparts and legs 1-4 similar to female.
- P5 with a 3-segmented endopod and exopod on left, basipod 2 usually modified with one or more inner extensions which may bear spines; exopod and endopod usually 2-segmented on right, last exopod segment recurved; basipod 1 on either side may sometimes be modified with extensions.

After Bode & al. (2018, p.75) the species in this genus were considered as primary detritivores and opportunistic carnivores, feeding on a wide variety of detritus, prokaryotic and eukaryotic autotrophs, bacterial aggregates and metazoans (Gowing & Wishner, 1998)
