Heterorhabdus prolixus Park, 2000 (F,M) | |
| | | | | | | Ref.: | | | Park, 2000 (p.120, figs.F,M, Rem.) |  issued from : T. Park in Bull. Scripps Inst. Oceanogr. Univ. California, San Diego, 2000, 31. [p.238, Fig.86]. Female: a, habitus (left side); b, urosome (dorsal); c, d, forehead (left, dorsal, respectively); e, f, genital somite (left, right, respectively); g, h, genital somite with operculum open (left, right, respectively). gfl = genital flange. Nota: Length ratios of 4 urosomal somites and left caudal ramus 37.8 : 17.7 : 15.2 : 8.6 : 20.7 = 100. Dorsal appendicular seta of left caudal ramus twice as long as that of right ramus. Anteriorly, caudal rami each with 2 pores.

 issued from : T. Park in Bull. Scripps Inst. Oceanogr. Univ. California, San Diego, 2000, 31. [p.239, Fig.87]. Female: a, genital somite (ventral); b, c, abnormal genital somite (left, dorsal, respectively). Nota: Genital field with 7-9 pores on each side. Male: d, P5 (anterior); e, basipod of right P5 (anterior); f, basipod of left P5 (anterior); g, second exopodal segment of right P5 (anterior); h, exopod of left P5 (anterior); i, distal end of exopod of right P5 (lateral).

 Heterorhabdus prolixus female: 1 - See key to species groups of Heterorhabdus: ''abyssalis'' Group (p.90, 114). 2 - Genital somite without a conical projection mediodorsally (Fig.86- a, d). 3 - Laterally, genital somite without a tubercular outgrowth posteriorly on dorsal margin (Fig.86-d). 4 - Laterally, genital operculum far short of reaching posterior end of somite (Fig.86-d). 5 - Laterally, right and left genital flanges asymmetrical (Fig.86-e, f). 6 - Laterally, left genital flange low, smoothly arched. 7 - Laterally, genital somite relatively elongate, typically with a length-depth ratio of 100:83 (Fig.86-e).

 Heterorhabdus prolixus male: 1 - See key to species groups of Heterorhabdus: ''abyssalis'' Group (p.90, 114). 2 - Basal inner lobe of left P5 short, finger-like. 3 - Basal inner lobe of left P5 distally rounded (Fig.87-f).

Carte de distribution de Heterorhabdus prolixus par zones géographiques
|
| | | | Loc: | | | E Pacif. equatorial, W America (39° S - 27° N), off N Chile
Type locality: 31°47'S, 75°03'W.
For Park (2000, p.121), the species, apparently, is endemic to the coastal waters of the east Pacific but may be carried westward to some distance in the equatorial currents. | | | | N: | 1 | | | | Lg.: | | | (824) F: 2,92-2,36; M: 2,88-2,28; {F: 2,36-2,92; M: 2,28-2,88} | | | | Rem.: | "Abyssalis" Group.
Park (2000, p.121) note une anormalité du somite génital.
