Female (from CVhikugo River): A-B, habitus (dorsal and lateral, respectively); C, 3rd prosome to 4th urosomite; D, last pediger (lateral); E, right half of last pediger, posterior (view from indicated with a white arrow in D); F, genital double-somite (dorsal); H, 2nd urosomite with dorsal spinules; I, caudal rami (dorsal); U, P5 (posterior). Nota: - 2nd and 3rd pedigers with row of fine spinules along posterolateral margin. - Lastb pediger on each side, with spiniform small dorsal attenuation, weakly protruding posterior projection, and 3 groups of spinules in rows, i.e., row of slightly curved, long spinules on dfistolateralmcorner (indicated by arrow with 'a' in fig. 1E), irregular rows of medium and fine spinules on distomedial surface (indicated by arrow with 'b'), and long transverse row of fine spinules on lateral surface (indicated by arrow with 'c'). - Genital double-somite with 2-4 fine spinules on anterolateral projection, 2 groups of a few fine dorsolateral spinules at about 1/3 and 4/5 length of somite, respectively, and fine lateral setule at mid length on each side. - Dorsal surface of 2nd free urosomite with transverse row of 2-5 fine spinules at about 3/5 length on each side. - Caudal rami length around 2.4 times width.

Locations from which Pdeudodiaptomus yamato (black circle) and P. japonicus (black triangle) have been recorded, with the location names appearing in the text.
Broken lines represent boundaries between their ranges.
The references are Sakaguchi & Ueda (2010, 2011) and the present study; the other five references are presented in parentheses.

| | | | Loc: | | | Japan (Chikugo, Manose, Kodono, Tama Rivers and a pond in Mie, S, E Honshu, Kyushu) | | | | Lg.: | | | (1235) F: 1,23-1,67; M: 1,10-1,30); {F: 1,23-1,67; M: 1,10-1,30} | | | | Rem.: | For UIeda & Sakaguchi (2019, p.29) this new species is endemic to Japan and confined to the coasts affected by the warm Kuroshio Current from western Kyushu to the middle of Honshu, while P. japonicus is widespread in northern East Asia without overlapping the range of P. yamato. The range of P. inopinusP. yamato and P. japonidcus.
The name yamato is the ancient name of Japan during the Kofun period between the 3rd and 6th centuries, this species being very close from japonicus | | | Dernière mise à jour : 05/09/2019 | |
