Heterorhabdus prolatus Park, 2000 (F,M) | |
| | | | | | | Syn.: | Heterorhabdus papilliger: Grice, 1962 (p.222, figs.M, no F), after Park (2000, p.110) | | | | Ref.: | | | Park, 2000 (p.109, figs.F,M, Rem.) |  issued from : T. Park in Bull. Scripps Inst. Oceanogr. Univ. California, San Diego, 2000, 31. [p.230, Fig.78]. Female: a, habitus (left side); b, c, urosome (left, dorsal, respectively); d, e, forehead (left, dorsal, respectively); f, g, h, genital somite (left, ventral, right, respectively). Nota: - Prosome length 70 % length of body and about 2.3 times length of urosome. - Forehead angular and produced ventrad into a small rostrum bearing 2 slender filaments. dorsally, midanterior tubercular process (fig.78 e) tapering into a pointed tip. - Cephalosome 46 % length of prosome, with a cervical groove halfway along dorsal margin - Posterolateral corner of prosome rounded. - Length ratios of 4 urosomal somites and left caudal ramus 38.8 : 18.7 : 13.7 : 8.8 : 20.0 = 100. - Left caudal ramus extending beyond posterior end of right ramus by about 1/5 its length( as measured along medial margin). Dorsal appendicular seta of left ramus almost twice as long as that of right ramus.; 4th marginal seta of left ramus much thicker than other marginal setae and longer than body. Dorsally, each caudal ramus with a relatively large pore. - A1 reaching close to posterior end of caudal ramus.

 issued from : T. Park in Bull. Scripps Inst. Oceanogr. Univ. California, San Diego, 2000, 31. [p.231, Fig.79]. Female: a, left Mx2 (posterior); b, P5 (anterior). Nota: Mx2: Falcate spine of 5th lobe with proximal 54 % of medial margin serrated with spinules; falcate spine of 6th lobe with proximal 63 % of medial margin serrated with spinules. (compare with H. spinifer fig.76 g). Male: c, right P5 (endopod omitted), anterior; d, left P5 (anterior); e, exopod of P5 (anterior). Nota male: - Prosome 71 % length of body; urosome 30 % length of body. - First 4 urosomal somites armed with relatively large spinules along posterior margins. - Caudal rami and setation as in female.

 issued from : G.D. Grice in Fish. Bull. Fish and Wildl. Ser., 1962, 61. [p.221, Pl.24, Figs.13-16]. As Heterorhabdus papilliger. Male (from equatorial Pacific): 13, habitus (lateral); 14, Mx2; 15, P5; 16, distal end of protrusion of 2nd exopodal segment of right P5.

 Heterorhabdus prolatus 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.78-e) and not produced into a spiniform process. P5 with inner marginal seta on 1st endopodal segment (Fig.79-b). 3 - Laterally, genital prominence extending far shorter to posterior end of somite (Fig.78-b).
|
 Heterorhabdus prolatus 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 and angular distally (Fig.79-d) 3 - In right P5, medial projection of 2nd exopodal segment not terminally expanded, somewhat truncate, with nearly parallel proximal and distal sides (Fig.79-c).
