Popis: Key to species of the subgenus Paramysis s. str. of the genus Paramysis Subgeneric diagnosis (updated from Daneliya 2004). Body large. The length of adults exceeds 20 mm. Head about as wide as the first abdominal segment. Frontal margin of carapace convex, smoothly rounded (Figs. 5 a, 6 a, b). Subrostral plate long. Telson equal to or slightly longer than the last abdominal segment, tapering distally, with fine setae along margins in addition to spine-setae; a small distal cleft armed with few (2 to 11) small denticles; terminal spine-setae long (Figs. 5 a, 7 a, b). Antennal scale considerably longer than antennular peduncle, about three times longer than wide. The outer spine-seta by the distal end of the antennal scale on the level of frontal margin or slightly beyond it (Figs. 4 b, 7 c). Mandibular palp with multiple relatively thin setae (Fig. 3 a). Endopod of maxilla II with two or three small spine-setae (Fig. 4 c). Carpopropodus of all pereiopods 4 -segmented (Figs. 4 d, c, 7 e, f). Paradactylar claw-setae with strong straight denticles (Figs. 4 d, c, f, 7 e). Penis posterior blade wide with 1���3 long distal setae (Fig. 5 b). Spine-setae of uropod endopod occupy more or less proximal part of the appendage (Fig. 5 a). 1 4 th segment of carpopropodus of pereiopod I barely more than half as long as 3 rd segment (Figs. 4 d; 7 e); setae of maxilla II exopod long (Figs. 4 c, 7 d), visible in dorsal view of head in the pleurocervical fissures (Figs. 5 a, 6 a, b); distal margin of basal segment of thoracopod exopod without setae (Fig. 3 c).............. 2 - 4th segment of carpopropodus of pereiopod I only slightly shorter than 3 rd segment; setae of maxilla II exopod short, invisible in dorsal view of the head in pleurocervical fissures; distal margin of basal segment of thoracopod exopod with long setae....................................................................................................................................

Sars, 1895; Caspian Sea, estuaries and rivers of North-West Black Sea 2 Antennal scale relatively narrow, about three times as long as wide (Figs. 4 b, 7 c); exopod of maxilla II rather wide, with long proximal and short distal setae (Figs. 4 c, 7 d).......................................................... 3
