Tanaka in Publs Seto Mar. Biol. Lab., 1964, XII (3). [p.238, Fig.224]. As Phyllopus impar. 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: Cephalothorax 2.00 mm; abdomen 0.88 mm. Last thoracic segment asymmetrical; right side more produced posteriorly and pointed at the apex. Abdominal segments and caudal rami in the proportional lengths 35 : 17 : 14 : 18 : 16 = 100. Caudal rami 1.6 times as long as wide. Genital segment inflated on each side of the lateral margin and slightly asymmetrical; right side more remarkable. A1 extends about to the end of the last thoracic segment. Male: e, right P5; f, left P5. Nota: Cephalothorax 2.01 mm; abdomen 0.90 mm. The last thoracic segment symmetrical, not pointed at the lateral distal margin. A1 extends about to the distal margin of the cephalothorax. P5 resembles that of helgae but the distal segment of the left leg differs in shape; in helgae the tooth of the distal segment is distinctly separated from the distal segment but in impar there is no distinct demarcation between the tooth and the segment.; the outer marginal claw is straight (as figured by Sars); the lamellous plate on the inner margin of the 2nd segment is narrow and has a small denticle on the distal margin. In the right leg the process on the inner proximal margin of the 3rd segment is slender and long.
