Tanaka in Publs Seto Mar. Biol. Lab., 1964, XII (3). [p.237, Fig.223]. As Phyllopus bidentatus. Female (from Izu region, Japan): a, habitus (dorsal); b, last thoracic segment and urosome (right lateral side); c, last thoracic segment and genital somite (left lateral side); d, P5. Nota: Head and 1st thoracic segment separate, 4th and 5th fused. - Last thoracic segment asymmetrical, right side more elongated and extends to the distal margin of the genital segment; lateral distal margin of the segment obliquely truncate. - Rostrum short and pointed. - Cephalothorax 2.06 mm, abdomen 0.95 mm. - Abdomen 4-segmented; the abdominal segments and caudal rami in the proportional lengths as 38 : 15 : 13 : 19 : 15 = 100. - A1 24-segmented, extends about to the middle of the 1st last thoracic segment. - Caudal rami about 1.3 times as wide as long. Male: e, right P5; f, left P5. Nota: The last thoracic segment symmetrical; the lateral corner rounded with a minute process on the posterior margin. - P5: distal segment of left leg swollen near the inner proximal margin and with a ttoth-like process on the distal end; a curved claw arises from the outer distal margin of the segment which is about half the length of the segment. In right leg, the 3rd segment has a characteristic club-shaped process on the inner proximal margin.

 isued from : Bradford-Grieve J.M. in The Marine Fauna of New Zealand: Pelagic Calanoid Copepoda. National Institute of Water and Atmospheric Research (NIWA). NIWA Biodiversity Memoir, 111, 1999. [p.130, Fig.89]. As Phyllopus bidentatus. Female (31°19.5'S, 165°19'E): A, habitus (dorsal); B, left posterior border of pedigerous segments 4+5; C, right (idem); D, P5. Male: E, habitus (dorsal); F, left P5; G, right P5. Female characteristics: A1 extends to posterior border of pediger segment 2. - Posterior corners of pedigers segments 4+5 asymmetrical longer on right, in lateral view the corners are cut off obliquely with an uneven border. - Genital segment almost symmetrical with an indentation on right dorsolateral surface. - P5 basipod 2 with a long outer distal seta extending further than whole leg. Male characteristics: Posterior corners of pediger segment 4+5 extend as far as posterior border of urosomal segment 1, rounded in lateral view. - P5 right exopod segment 2 with a proximal peg-like extension; left leg terminal spine-like segment, short. Nota: The present specimens do not agree with Brady's (1883) drawing of this species in that the right extension of pedigerous segments 4+5 is shown by him to have a ventral protrusion which is sharply pointed rather rounded. The present specimens agree with those of A. Scott (1909) in this respect.
