Lucicutia sewelli Tanaka, 1963 (F,M) | |
| | | | | | | Ref.: | | | Tanaka, 1963 (p.28, Descr.M, figs.M); Hülsemann, 1966 (p.736, Descr.F, figs.F, Rem.); Boxshall & Halsey, 2004 (p.133: F; p.135: M) |  issued from : O. Tanaka in Publs Seto Mar. Biol. Lab., 1963, XI (1). [p.29, Fig.161]. Male: habitus (dorsal); b, A2; c, Mxp; d, P1; e, exopod of P2; f, P5. Nota: The urosome segments and furca: proportional lengths as 10:9: 9:7:15:50 = 100. Rostrum bifurcates with a slender filament at each distal end. Right A1 25-jointed, left with 21 free segments.

 Issued from : K. Hülsemann in Bull. Mar. Sc., 1966, 16 (4). [p.716, Figs.47-49]. Female (from W Indian): 47, habitus (lateral left side); 48, P1; 49, P5. Nota: In dorsal view, head truncate, rostrum visible. A1 25-segmented, exceeding ed of furca by 4 to 5 segments. Endopod of P1 2-segmented. Terminal spine of P5 as long as 3rd exopodal segment.

 Issued from : K. Hülsemann in Bull. Mar. Sc., 1966, 16 (4). [p.722, Fig.85]. Female: 85, urosome (dorsal). Nota: Abdomen contained about two times in cephalothorax. Furca nearly as long as abdomen, about nine times longer than wide proximally. Anal segment longer than preceding segment.
|
 Lucicutia sewelli 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 2-segmented endopod. 3 - Cephalosome not with 2 pairs of lateral spinous projections, but with other forms. 4 - Distal 4 to 5 segments of A1 reaching beyond tip of caudal ramus. 5 - Caudal rami about as long as urosome and 9 times longer than wide.
|
 Lucicutia sewelli male: 1 - P1 with 2-segmented endopod; 2 - Caudal rami less than 10 times longer than wide. 3 - Inner distal corner of basis of P5 without strong spine. 4 - Basis of left P5 ornamented differently from L. oblonga. 5 - Caudal rami about 3 to 5 times longer than wide. 6 - A1 at most reaching to end of caudal rami; basis of left P5 different from L. longiserrata. 7 - Cephalosome without lateral projections (in dorsal view); right A1 reaching only to tip of caudal rami; inner margin of basis of right P5 with small tooth-like projection; inner distal corner of basis of left leg not ending in single point. 8 - Lateral spinous processes on cephalosome directed posterolaterally; caudal rami as long as urosome.

Distribution map of Lucicutia sewelli by geographical zones
|
| | | | | |  Chart of 1996 | |
| | | | Loc: | | | Caribbean Sea, Caribbean Colombia, off Bermuda (Station "S"), Sargasso Sea, W Indian, Japan (Sagami) | | | | N: | 6 | | | | Lg.: | | | (21) F: 4-3,6; (26) M: 3,77; {F: 3,60-4,00; M: 3,77} | | | | Rem.: | Deep water of Sagami Bay. Overall Depth Range in Sargasso Sea: 1500-2000 m (Deevey & Brooks, 1977, Station "S");
The male resembles L. tenuicauda.
For Hülsemann (1966, p.737) the female is distinguished from L. magna and L. pacifica by the longer furca and the longer terminal spine on the exopod of P5. It differs from L. tenuicauda by its longer A1. | | | Last update : 16/01/2015 | |
