Distribution map of Metridia gurjanovae by geographical zones
Station Knot, Bering Sea, Station "P" (50°N, 145°W), N & S Chile (in Björnberg, 1973), off Mauritania (in Vives, 1982, p.293)
N: 5
(22) F: 3,45; M: 3; (205) M: 3; {F: 3,45; M: 3,00}
Rem.: Nomen nudum in Epstein, 1949, described by Brodsky (1950).
For Brodsky (1967, p.301) this species differs from the closely similar M. brevicauda Giesbrecht in the 4-segmented P5 of the female, in the much smaller difference in the length of rhe right and left legs of P5 male.
For Vaupel-Klein (1970, p.35) the structure of P5 of the males of the species M. pacifica, gurjanovae and probably also M. asymmetrica is very similar and might be an indication of a closer relationship between these three species.
The geographic distribution of this form is surprising.
