Remarks. Polyonyx pedalis  is unique among members of the P. sinensis  group, as defined by Johnson (1958) in having numerous small spines on the flexor margins of the meri of the ambulatory legs. All the male specimens examined lack gonopods as noted by Haig (1964) in juvenile specimens.

Osawa (2007) provided the illustrations of a specimen examined of P. pedalis  and discussed the distinctions between this species and its close relative, P. s p i n a Osawa, 2007.

Distribution. Previously known from Red Sea and Kei Islands to a depth of about 50 m ( Haig 1964). The present record of the species from New Caledonia greatly extends its distribution to the southwestern Pacific. The specimens examined were obtained from the depths of 10–65 m in New Caledonia.
