Figures

Planche 1 issued from : O. Tanaka in Publs Seto Mar. Biol. Lab., 1964, XII (1). [p.89, Fig.218]. As Pachyptilus pacificus.
Female: a, habitus (dorsal); b, forehead (left lateral side); c, last thoracic segment and urosome (left lateral side); d, rostrum (frontal view); e, left Md; f, masticatory edge of right Md; g, P1; h, P5.
Nota: The urosome segments and furca are in the proportional lengths as 50:12:8:10: 20 = 100. A1 exceeds the end of the furca by distal 4 segments.

Species Pseudhaloptilus pacificus - Planche 4 of morphological figures

Planche 4 Issued from : K.A. Brodskii in Calanoida of the Far Eastern Seas and Polar Basin of the USSR. Opred. Fauna SSSR, 1950, 35 (Israel Program for Scientific Translations, Jerusalem, 1967) [p.392, Fig.279]. As Paachyptilus pacificus.
Female (from NW Pacif.): habitus (dorsal and lateral right side); GVe, forehead (ventral); GLa, idem with protruding labrum (lateral); M, Md (masticatory blade); S1, P1; S5, P5.
Nota: Cephalotorax, especially the lateral part and the protruding part of the labrum, covered with shining refractile specks, resembling hardened droplets of fat.

Species Pseudhaloptilus pacificus - Planche 5 of morphological figures

Planche 5 issued from : M.W. Johnson in Bull. Scripps. Instn. Oceanogr., tech. Ser., 1936, 4 (2). [p.67, Fig.A, 4-5].
Female (from 49°20'N, 174°31'W): 4-5, habitus (dorsal and lateral, respectively).
Nota: 5th thoracic segment with moderately pointed margins. Urosome about 1/4 the length of prosome. Genital segment about equal in length to the 3 abdominal segments combined. Caudal rami slightly longer than the anal segment. 2nd inner caudal setae much longer than the others. A1 extending beyond the caudal rami by approximately the 4 end segments

Species Pseudhaloptilus pacificus - Planche 6 of morphological figures

Planche 6 issued from : M.W. Johnson in Bull. Scripps. Instn. Oceanogr., tech. Ser., 1936, 4 (2). [p.68, Fig.B].
Female: 1, Mx1; 2, right Md; 3, left Md (mandibular blade); 4, A2; 5, Mx2; 6, Mxp; 7, P3; 8, P1; 9, P5; 10, rostal filaments.
Nota: Labrum very large and armed with a posterior tuft of short rigid spinules. A2 7-segmented. Mandibular blades very strongly developed. P5 symmetrical, exopod 3-segmented and endopod 1-segmented with 4 setae.

Species Pseudhaloptilus pacificus - Planche 7 of morphological figures

Planche 7 issued from : S. Ali-Khan & J. Ali-Khan in Crustaceana, 1984, 47 (3). [p;311, Figs.44-51].
Female (from 24°09'N, 64°27'E): 44, habitus (dorsal); 45, rostrum; 46, right Md (biting edge); 47, left Md (biting edge); 48, Mx1; 49, Mx2; 50, P1; 51, P5.

Nota: There is no spine on lobe 4 of Mx2 as noted by Tanaka (1964). Johnson's (1936) figure of the A2 which shows the outer lobe of the endopod as a segment, seems an artifact, and similarly the 3 lateral spines shown on the 3rd exopodal segment of right P5 are either incorrect or present an abnormal case, since the same segment of left P5 of Johnson's specimen has 2 spines and all other species in this genus also have 2 lateral spines.

Planche 8 Issued from : G.A. Boxshall & S.H. Halsey in The Ray Society, No 166, 2004. [p.69, Fig.7, D].
Female : D, Md.
