Distribution map of Lucicutia macrocera by geographical zones
Species Lucicutia macrocera - Distribution map 3issued from : W. Vervoort in B.A.N.Z. Antarctic Reseach Expedition, Reports - Ser. B, Vol. III, 1957 [Fig.120]
Chart showing the geographical distribution (white circle) in the seas surrounding the Antarctic continent.
Nota: In this chart the area frequented by whaling vessels has been hatched. The Antarctic circle (66°.5 S) has been drawn as a broken line. The numbers I to VI refer to the sectors into which the Antarctic seas are divided according to Mackintosh (1942) (after Vervoort, 1951).

Body size: F: 3,3 - 4,05 (Sars, 1925; Vervoort, 1957; Tanaka, 1963; Wilson, 1932a; Séret, 1966; Bradford-Grieve, 1999b)

Body size: F: 4,70 - 5,00 (Brodsky, 1950; Heptner, 1969)
Rem.: meso & bathypelagic (500-7100 m).
Sampling depth (Antarct., sub-Antarct.) : 500-1000 m. Sargasso Sea: 500-2000 m (Deevey & Brooks, 1977, Station "S");
A doubt subsists on the synonymy with Lucicutia pacifica. All authors are not in accordance on the synonymy between L. macrocera and L. pacifica Brodsky, 1950; for this latter the species differs from the closely related L. macrocera Sars in its greater size and shorter antennules, as well as in the structure of P5 male. After Boxshall & Halsey (2004, p.133): Distal 4 to 7 segments of A1 female reaching beyond tip of caudal ramus, whereas in L. pacifica, distal 4 to 5 segments of A1 female reaching beyond tip of caudal ramus. In the male of L. macrocera, the inner distal corner of basis without strong spine, whereas in L. pacifica male the inner distal corner of basis with 1 strong spine. The body lengths are also different, smaller in L. macrocera than L. pacifica. Nevertheless a doubt subsists because the sizes are not a good character as the length of antennules in relation to environmental factors.
For Hülsemann (1966, p.727) the P5 male figured and ascribed to L. magna by Wilson (1932) is that of L. macrocera.
