Figures
Planche 1 issued from : T. Park in Bull. Scripps Inst. Oceanogr. Univ. California, San Diego, 2000, 31. [p.232, Fig.80]. Female: a, habitus (left side); b, c, urosome (left, dorsal , respectively); d, genital somite (left), e, genital somite with operculum open (left); f, genital somite (ventral); g, h, i, genital somite with a tubercular outgrowth (dorsal, left, right, respectively); j, left Mx2 (posterior).
Nota: Prosome length 70 % length of body and about 2.2 times length of urosome. Forehead (laterally) with rounded anterior end and produced ventrad into a conical rostrum bearing 2 selender filaments. A1 extending beyond posterior end of caudal ramus by its last 1 or 2 segments. Mx2: 2nd seta of 1st lobe approximately 1/3 length of 1st seta. Posterior subterminal spine of 4th lobe 68% as long as2nd saberlike spine, which is only slightly longer than 1st. Saberlike spine of 5th lobe 83% as long as falcate spine. Genital somite with a tubercular outgrowth on dorsolateral side and close to posterior end. Genital field with 7-16 pores on left side and about 25 pores on right side. Length ratios of 4 urosomal somites and left caudal ramus 36.4 : 18.8 : 13.9 : 9.1 : 21.8 = 100.
Planche 2 issued from : T. Park in Bull. Scripps Inst. Oceanogr. Univ. California, San Diego, 2000, 31. [p.233, Fig.81]. Female: a, right Mxp (anterior); b, distal part of basis of right Mxp (anterior); c, idem, from different specimen (anterior); d, exopod of P1 (anterior); e, exopod of P5 (posterior).
Male: f, P5 (anterior); g, h, second exopodal segment of right P5 (anterior, posterior, respectively); i, exopod of left P5 (anterior).
Planche 3 issued from : O. Tanaka in Publs Seto Mar. Biol. Lab., 1964, XII (1). [p.8, Fig.177]. Female: a, urosome (dorsal); b, last thoracic segment and genital somite (lateral left side); c, Mxp; d, P5. Nota: The urosome segments and furca are in the proportional lengths as 44:14:10:7:25 (right) = 100. The genital somite is slightly asymmetrical. A1 over-reaches the furcal rami by 2 terminal segments
Male: e, right P5; f, left P5; g, 1st and 2nd segment of exopod of left P5. Nota: The urosome segments and furca are in the proportional lengths as 22:17:16:12:9:24 = 100. A1 extends to the distal margin of the anal segment.
Planche 4 issued from : M.V. Heptner in Trudy. Inst. Okeanol., 1971, 92. [p.150, Fig.36]. Female & Male; forma tuberculata Figs. 1, 2, 5-8. Forma typica Figs. 3, 4, 9, 11.
Planche 5Heterorhabdus fistulosus female: 1 - See key to species groups of Heterorhabdus: ''fistulosus'' Group (p.90, 110). 2 - Dorsally, genital somite widest in anterior half; dorsally as well as laterally, genital prominence for short of reaching posterior end of somite (Fig.80-g, h).
Planche 6Heterorhabdus fistulosus male: 1 - See key to species groups of Heterorhabdus: ''fistulosus'' Group (p.90, 110). 2 - Basal inner lobe of right P5 elongate (Fig.81-f). Lateral conical process and outer spine of 2nd exopodal segment of left P5 elongate, their combined lengths approxiamtely 2/3 length of segment (Fig.81-i).
