Species Lucicutia formosa - Plate 1 of morphological figuresIssued from : K. Hülsemann in Bull. Mar. Sc., 1966, 16 (4). [p.708, Figs.14-17].
Male (from 30°01'N, 23°00.7'W)): 14, head (dorsal); 15, idem (lateral); 16, P5; 17, right P5 (other view).
Nota: Each side of head with two protrusions, the posterior one more obtusely pointed than the anterior one which is directed downward. Right A1 exceeds end of furca by 2 segments. 2nd basipodal segment of P1 with tube-like protrusion. Endopod of P1 3-segmented. Inner proximal corner of 2nd basipodal segment of right P5 set off \"wrinkled\"; Inner distal corner of 2nd basipodal segment of left P5 protruded with small teeth.

Species Lucicutia formosa - Plate 2 of morphological figuresIssued from : K. Hülsemann in Bull. Mar. Sc., 1966, 16 (4). [p.722, Fig.96].
Male: 96, urosome (dorsal).
Nota: Furca almost as long as abdomen, 9 times longer than wide. Anal segment longer than preceding segment.

Species Lucicutia formosa - Plate 3 of morphological figuresissued from : M.V. Heptner in Trudy. Inst. Okeanol., 1971, 92. [p.130, Fig.27]. As Lucicutia gigantissima
Female (from Kuril-Kamchatka Trench). psb I, process on outer margin of basipod of P1.
Nota: Heptner (1971, p.129) rectifies the name (comm pers.).

Species Lucicutia formosa - Plate 4 of morphological figuresLucicutia formosa female:
1 - Characters following not combined : Prosome about 3 times longer than urosome. Cephalosome with slightly projecting and rounded anterior corners and well developed lateral spinous projections; anal somite about as long as wide; caudal rami 11.7 times longer than wide and bowed outwards at base, leaving elliptical space between rami proximally.
2 - P1 with 3-segmented endopod.
3 - Cephalosome with 2 pairs of spinous projections (1 anterolateral and 1 lateral).
4 - Anterolateral projections forming slightly recurved hook. Anal somite asymmetrical, with swelling on left side. Caudal rami shorter than urosome.

Species Lucicutia formosa - Plate 5 of morphological figuresLucicutia formosa male:
1 - P1 with 3-segmented endopod.
2 - Cephalosome with 2 pairs of spinous projections (1 anterolateral and 1 lateral).
3 - Anterolateral projections small; lateral projections directed ventrally.
4 - Anal somite longer than preceding somite; caudal rami about 9 times longer than wide.

Distribution map of Lucicutia formosa by geographical zones
Species Lucicutia formosa - Distribution map 2
Chart of 1996
Canary Is., G. of Mexico, Sargasso Sea E, W Indian, Kuril Is., Chile (40°S, 76°W).

Type locality: 30°01'N, 23°00.7'W.
N: 5
(21) M: 8,6-7,6; (23) F: 10,25; {F: 10,25; M: 7,60-8,60}
Rem.: abyssopelagic (3600-6900 m).
According to Hülsemann (1966, p.715) this species is distinguished from L. maxima by its longer furca and anal segment, and from L. bella and L. pallida by the 2 protrusions on each side of the head and the structure of P5 in the male.
