биота российских вод японского моря - Materials of Alexey Shipunov

It should be noted that there is no yet consensus on the system of the order. Manyresearchers establish only two suborders within the order Mysidacea, viz. Lophogastridaand Mysida, including the other two suborders into the suborder Mysida. Otherauthors erect the suborder Lophogastrida as a separate order (Martin & Davis, 2001).Some biologists don’t accept the independence of the families Gnathophausiidae andBoreomysidae. There is no general agreement among authors as to the number of tribesin the subfamily Mysinae. Some workers separate only four tribes (Erythropini,Leptomysini, Mysini, and Heteromysini) and attribute the rest to the tribe Erythropiniand one genus to the tribe Leptomysini.Members of the suborder Mysida and the family Mysidae have been found in theRussian waters of the Sea of Japan.Systematic partSuborder Mysida Boas, 1883Branchiae on thoracopods absent. Basal part of endopod of uropod provided withstatocyst.I. Family MYSIDAE Dana, 1850Female marsupium consists of two, rarer three pairs of well-developed oostegites(in some genera rudimentary pairs of oostegites also present). (Species inhabiting theRussian waters of the Sea of Japan have one-segmented exopod of uropod; no rudimentarysuture; outer margin covered with numerous (more than 10) spines, but withoutsetae, or covered with numerous setae, but without spines).Only two subfamilies of six occur in the northern part of the Sea of Japan.KEY TO THE SUBFAMILIES OF THE FAMILY MYSIDAE1(2). Female marsupium consists of two pairs of oostegites and one pair of lateral (epimeral)lamellae of first abdominal segment (pl. II, fig. 6). Outer margin of exopodof uropod without setae, with 1, 2, or more spines (pl. II, fig. 3) ........................................................................................................... I. Gastrosaccinae (p. 44)2(1). Female marsupium consists of 2, rarer 3 pairs of oostegites, lateral (epimeral)lamellae on first abdominal segment absent (pl. IV, fig. 6; XIV, fig. 2). Outermargin of exopod of uropod without spines, with numerous setae (pl. III, fig. 6) .................................................................................................... II. Mysinae (p. 46)I. Subfamily Gastrosaccinae Norman, 1892Female marsupium consists of two pairs of oostegites and one pair of epimerallamellae of first abdominal segment. Exopod of uropod one-segmented, outer marginwith one, two, or more spines, without setae from distal spine to base of exopod.Only one genus (Archaeomysis) of eight ones constituting the subfamily Gastrosaccinaeis found in the Russian waters of the Sea of Japan.44
