Distributional records of D. pectinatus (1985). |
 issued from : W. Vervoort in B.A.N.Z. Antarctic Reseach Expedition, Reports - Ser. B, Vol. III, 1957 [Fig.10].
Chart showing the geographical distribution (white triangle) 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). |
 Issued from : A.C. Hardy & E.R. Gunther in Discovery Reports, 1935 (1936), 11. [p.153, Fig.73].
Charts showing the distribution of Drepanopus pectinatus ( = Drepanopus forcipatus) in the upper layers of waters at stations in the 1926-7 surveys around South Georgia.
The squares represent the average numbers per 50 m vertical haul from 250 m (or less at shallow-water stations) to the surface with N 70 V nets. |

Female (from off N Kerguelen Is.): Lengths of Cephalothorax at two stations: 4 (50°05'S, 70°28'E) and 5 (50°35'S, 69°29'E) from the same date 05.04.1974; surface temperature: 3.64°C and 3.74°C, respectively. |
 Issued from : C. Séret in Thesis UPMC, Paris 6. 1979 [p.62].
Female: Frequency distribution of cephalothrax length (L.Cth) from station 4 and 5.
Nota: The author notes the lengths of females are higher at the station 4 (closest of Islands) than those at station 5. |

N (in Wilson, 1942 a)] | | | | N: | 24 | | | | Lg.: | | | (25) F: 2,7-1,8; M: 1,8-1,58; (114) F: 3-2,7; (246) F: 2,57-1,78; {F: 1,78-3,00; M: 1,58-1,80} | | | | Rem.: | Néritique.
Sampling depth (Antarct., sub-Antarct.) : 0-250 m.
La forme signalée par Wilson (1942 a, p.17) sous ce nom (par 44 ° N, 33° W) est plus vraisemblablement Drepanopus bungei.
La courbure de la P5 permet de distinguer aisément cette espèce de D. forcipatus.
L'espèce a été décrite pour la première fois aux Iles Kerguelen par Brady. Elle n'a été trouvée qu'aux abords des Îles sur le plateau continental, ce qui en fait une espèce typiquement néritique sans doute nécessitant des apports terrigènes et récoltée en petit nombre dans les eaux du large.
