Heterorhabdus guineanensis Park, 2000 (F,M) | |
| | | | | | Ref.: | | | Park, 2000 (p.104, figs.F,M, Rem.) | issued from : T. Park in Bull. Scripps Inst. Oceanogr. Univ. California, San Diego, 2000, 31. [p.224, Fig;72]. Female: a, habitus (left side); b, c, urosome (left, dorsal, respectively); d, e, forehead (dorsal, left, respectively); f, genital somite with operculum partially open (left); g, genital somite with operculum closed (left); h, genital somite (ventral); i, left Mx2 (posterior). Nota: Prosome length 71 % length of body and about 2.4 times length of urosome. Forehead with widely angular anterior end and produced ventrad into a small rostral lobe bearing 2 slender filaments. Mx2: 2nd seta of 1st lobe very small, about 1/5 length of 1st; subterminal posterior spine of 4th lobe 63% as long as 2nd saberlike terminal spine, which is only slightly longer than 1st. Falcate spine of 5th lobe only slightly longer than saberlike spine, with proximal 55% medial margin serrated with spinules. Falcate spine of 6th lobe with proximal 64% of medial margin serrated with spinules.

Heterorhabdus guineanensis female: 1 - See key to species groups of Heterorhabdus: ''papilliger'' Group (p.90, 102). 2 - Midanterior tubercular process of forehead produced into an angular process (Fig.72-d) and not produced into a spiniform process. P5 with inner marginal seta on 1st endopodal segment (Fig.73-b). 3 - Laterally, genital prominence extending down to posterior end of somite (Fig.72-b). 4 - Laterally, genital prominence more or less rounded, with a moderately sloping anterior wall making an angle of about 60° with longitudinal axis of somite (Fig.72-b). 5 - Laterally, posteroventral margin of genital somite highly inflated (Fig.72-g).

Heterorhabdus guineanensis male: 1 - See key to species groups of Heterorhabdus: ''papilliger'' Group (p.90, 102). 2 -Midanterior tubercular process of forehead angular and not produced into a spiniform process. Basal inner lobe of left P5 rather poorly developed (Fig.73-e). 3 - In right P5, medial projection of 2nd exopodal segment terminally expanded, with a large rounded proximal lobe (Fig.73-e). 4 - In medial projection of 2nd exopodal segment of right P5, distal lobe below terminal spiniform process produced distad into a large toothlike process and larger than proximal lobe (Fig.73-g).

Type locality: 01°10'N, 11°36'W.
For Park (2000, p.105), the species is apparently endemic to the eastern Atlantic. | | | N: | 1 | | | Lg.: | | | (824) F: 2,34-2,18; M: 2,06-2,02; {2,18-2,34; M: 2,02-2,06} | | | Rem.: | "Papilliger" Group. For Park (2000, p.105) this species is closely related to H. papilliger and H. lobatus. | | | Last update : 20/05/2017 | |
