The mean female size is 0.764 (n = 11; SD = 0.1193). | | | Rem.: | epipelagic. After Tanaka (1960, p.24) the specimen from the South China Sea though much smaller in size than those thiterto been reported agrees qite well with the description and figures given by Sewell or by Farran. The species is closely allied to P. aculeatus but can be distinguished from the latter by its small size and by the structure of P5. According to Sewell a row of leaf-like spines that is present on the posterior surface of the 2nd exopodal segment of P4 in P. aculeatus appears to be always absent in P. denudatus. But the author has observed this row of spines in the female specimens taken from the Izu region (Japan). According to Vervoort (1963b, p.108) there is little doubt that Sars' P. pygmaeus and P. denudatus Sewell are conspecific; the shape of the body is practically identical in both species and the differences in the spinulation of the legs fall within the normal degree of variability. For Andronov (1977, p.154) and Bradford-Grieve (1994, p.67) this species is a synonym of Paracalanus pygmaeus (Claus,1863), in contrary to the opinion of Vervoort (1963 b, p.109) for whom this latter species is not identifiable. Vives & Shmeleva (2007, p.673) consider the female of P. pygmaeus different from P. denudatus referring to the length of the terminal seta of the P5 in proportion to the second segment, which does not carry the conviction. After Benedetti & al. (2018, p.1, Fig.2) this species belonging to the functional group 4 corresponding to small filter feeding herbivorous and mixed feeding omnivorous (mostly broadcasters).
