| | | | | | | Ref.: | | | Park, 2000 (p.125, figs.F,M, Rem.) |  issued from : T. Park in Bull. Scripps Inst. Oceanogr. Univ. California, San Diego, 2000, 31. [p.246, Fig.94]. Female: a, habitus (left side); b, c, urosome (left, dorsal, respectively); d, e, forehead (left, dorsal, respectively); f, g, genital somite (ventral, left, respectively); h, genital somite from different specimen (left); i, left Mx2 (posterior). Nota: Urosome 30% length of body. Length ratios of 4 urosomal somites and left caudal ramus 37.6 : 17.6 : 13.9 : 9.1 ; 21.8 = 100. A1 extending beyond posterior end of caudal ramus by its last 3 or 4 segments. Mx2: Posterior subterminal spine of 4th lobe 40% as long as 2nd saberlike spine; falcate spine of 5th lobe with proximal half of medial margin serrated with spinules and approximately 1.2 times length of saberlike.

 Heterorhabdus oikoumenikis female: 1 - See key to species groups of Heterorhabdus: ''abyssalis'' Group (p.90, 114). 2 - Genital somite without a conical projection mediodorsally (Fig.94- a, b). 3 - Laterally, genital somite without a tubercular outgrowth posteriorly on dorsal margin (Fig.94-b). 4 - Laterally, genital operculum far short of reaching posterior end of somite (Fig.94-b). 5 - Laterally, right and left genital flanges symmetrical. 6 - Laterally, genital prominence gradually merging onto ventral wall of somite (Fig.94-b). 7 - Dorsally, genital somite only slightly asymmetrical (Fig.94-c).

Carte de distribution de Heterorhabdus oikoumenikis par zones géographiques
|
| | | | | | | | | | Loc: | | | Atlant. (S-N), W Gulf of Guinea, SW Indian, Malay Archipelago, China Seas (East China Sea, South China Sea), Pacif. (E-W: 40° N - S)

For Park (2000, p.126), this species has an extremely wide distribution, taken in the Atlantic between 35°19' S and 63°24' N; throughout the Pacific between 41°27' S and 40°35' N, and from the west coast of the America westward to the Malay Archipelago and East and South China Seas; also in the Indian Ocean at 28°05' S, 66°05' E. | | | | N: | 1 | | | | Lg.: | | | (824) F: 3,52-2,6; M: 3,28-2,4; {F: 2,60-3,52; M: 2,40-3,28} | | | | Rem.: | "Abyssalis" Group.
Cette espèce présente une très vaste distribution en Atlantique et dans le Pacifique, malheureusement sans précision des localités dans le document consulté.
