*Nymphon longitarse brevicollis Losina-Losinsky, 1929(Pl. IV, figs. 6–11)Losina-Losinsky, 1933: 68–69; 1935: 30–34, fig. 4; 1961: 65–66; Hedgpeth, 1949: 248;1963: 1331 (Nymphon longitarse brevicollis).Description. This subspecies differs from nominative species in more compacttrunk. Neck shorter and thicker, shorter than half of cephalic segment; ocular tuberclelow, with flat top; proboscis only 1.5 times as short as cephalic segment of trunk. Legsnot as thin as in N. longitarse longitarse, but of same length; tarsus only 1.5 timeslonger than propodus; usually propodal sole lacks larger spines; auxiliary clawsnoticeably longer and reach 1/3 of main claw. Palp rather long; its segment 4noticeably, sometimes even twice, shorter than segment 5, but in some specimensthese segments may be almost equal, like those in N. longitarse longitarse.Geographical distribution. This subspecies is mainly high arctic, but alsooccurs near Sakhalin Island (at the Terpenyia Bay entrance) and on the Pacific Oceanside of the South Kuril Islands. In some regions N. longitarse brevicollis is foundalong with N. longitarse longitarse.5. Nymphon bisseratum Losina-Losinsky, 1961(Pl. III, figs. 1–6)Losina-Losinsky, 1961: 66, fig. 4.Description. Trunk robust, smooth; lateral processes separated by less than theirown diameters, longer than trunk width, slightly expanded distally; each with severallong setae dorsally on distal margins. Cephalic segment equal to or longer thananother part of trunk, slightly broadened anteriorly; neck elongated. Ocular tuberclelow, with rounded top, situated near base of neck, opposite oviger implantation; eyeslarge, pigmented. Proboscis cylindrical, noticeably shorter than cephalic segment.Abdomen long, reaches as far as distal edge of 1st coxae of 4th legs. Chelifore feeble;scape equal to proboscis and to chela, fingers equal to palm in length, gently curved,bearing small teeth. Palp 1.5 times longer than proboscis; its segments 2 and 3 equal;segment 4 twice shorter than segment 5; both distal segments covered with short setae.Compound spines of oviger with rounded tips and with only one pair of lateral teeth.Strong legs covered with setae; 2nd coxa longer than 1st and 3rd combined; tibia 1longer than femur; tibia 2 much longer than tibia 1; tarsus slightly shorter thanpropodus. Main claw almost 3 times shorter than propodus; auxiliary claws longerthan half of main claw. Propodal sole bears 6–7 large spines medially and distally andseveral spinules between them. Measurements of only one specimen available: trunklength 7.25 mm, proboscis 1.5 mm, palp 2.2 mm, leg 21.4 mm.Geographical distribution. The only specimen was caught in the Sea of Japannear the western coast of the South Sakhalin, near the town of Nevelsk, at a depth of101 m.100
