Quasimelita serraticoxae sp. nov. Figures 1, 16–23, 30 c, d Diagnosis . Pleon segments 2 and 3 with small single mid-dorsal tooth each. Urosome segment 1 with mid-dorsal tooth; urosome 2 with 2 pairs of short dorsal teeth, with single cuspidate seta among each lateral pair. Anterior margin of head truncated, without distinct anterior head lobe, lower antennal corner acute, pointed, lower margin with prominent accessory process. Eye small, round, poorly distinguishable, with pale ommatidia. Coxa 1 with acute, pointed anterior corner; anterior margins of all coxae with distinct serrations. Coxal plates 1 and 2 longer than plates 3 and 4. Propodus of pereopod 1 (male) relatively small, shorter than carpus, not broad distally, palm oblique, pass into the posterior margin without distinct angle; smooth palm that is armed distally with numerous closely set small cuspidate setae. Pereopod 2 (male), anterior margin of dactyl strongly setose; palm oblique, incorrectly toothed, with strong tooth at the palmar angle, with stout short simple setae along the palmar margin, and with clusters of long simple setae. Maxilla 1, inner plate with 8 marginal setae; palp segment 1 with 3–5 lateral setae. Maxilla 2, facial setae of inner plate very reduced (4–5 setae), lined in distal half of inner margin, closely submarginal. Uropod 3 is medium length, peduncle only 1.6 times shorter than outer ramous, proximal segment of outer ramous with 4–5 clusters of marginal stout simple setae; terminal segment distinct, short, length as 1/7 of proximal segment. Telson lobes with acute tips. Type material . Holotype male, 8.5 mm, 41805/Cr-1510, north-east shelf of Sakhalin Island, Okhotsk Sea, Far East of Russia (51°19'16''N 144°0'10''E, 116 m), silt, I.N.
