II. Subfamily Mysinae Hansen, 1910Female marsupiums consist of 2–3 pairs of oostegites; epimeral lamellae absenton first abdominal segment. Outer margin of exopod of uropod bears setae, no spines.The subfamily Mysinae comprises six tribes; the species of two of them inhabitthe northern part of the Sea of Japan.KEY TO THE TRIBES OF THE SUBFAMILY MYSINAE1(2). Carpus and propodus of each endopod of thoracopods 3–8 with obliquely articulated(pl. III, fig. 4). Outer margin of antennal scale (or at least its basal third)smooth, unarmed, often with distal spine (pl. III, fig. 2; pl. IV, fig. 1–5); sometimesantennal scale absent or reduced to spine. Male pleopods 2–5 well developed,biramous, natatory .................................................... 1. Erythropini (p. 46)2(1). Carpus and propodus of each endopod of thoracopods 3–8 fused, with secondarydivision into subjoints; no oblique articulation (pl. VI, fig. 5; XVI, fig. 4) (exceptfor genus Inusitatomysis (pl. V, fig. 5). Forms of antennal scale and telson greatlyvary: mysids from Russian waters of Sea of Japan have outer margin of antennalscale setose, without spines (pl. VI, fig. 3; VII, fig. 3), or saw-toothed,without setae (pl. V, fig. 3). In males at least second pleopod rudimentary anduniramous. Exopod of fourth pleopod in males elongate and modified (pl. VI,fig. 4; VII, fig. 5), except for genus Inusitatomysis: endopod elongate and exopodrudimentary (pl. V, fig. 6) ................................................ 2. Mysini (p. 49)1. Tribe Erythropini Hansen, 1910Stalked eyes well developed, have ordinary shape or visual elements of eyes dividedinto two distinct regions. Antennal gland not hypertrophied. Outer margin ofantennal scale, or at least its basal third, smooth, unarmed (armed with setae only ingenus Nipponerythrops). Sometimes antennal scale absent or reduced to spine. Carpusand propodus of each endopod of thoracopods 3–8 obliquely articulated (except forgenus Arachnomysis). Male pelopods 2–5 well developed, biramous, natatory. Telsonentire, without cleft.Two of twenty-nine genera of this tribe (under the classification by Tchindonova(1981)) are found in the Sea of Japan.KEY TO THE GENERA OF THE TRIBE ERYTHROPINI1(2). Lateral margins of distal half of telson armed with spines (pl. III, fig. 7) (Endopodof male pleopod 4 elongate and with strong seta on apex [pl. III, fig. 5]) ...................................................................................................... 1. Holmesiella (p. 47)2(1). Lateral margins of telson smooth, unarmed (pl. IV, fig. 4–7). (Male pleopod 1with normally developed, many-segmented exopod and unsegmented endopod(pl. IV, fig. 2), other male pleopods well developed and have normal shape[pl. IV, fig. 3]) ................................................................... 2. Meterythrops (p. 47)46
