| Summary: | Desdimelita (?) spicatimanus sp. nov. Figures 1–7 Diagnosis. Pleon segment 2 with or without small single mid-dorsal tooth. Pleon segment 3 with small single middorsal tooth. Urosome segment 1 with small mid-dorsal tooth; urosome 2 with 2 pairs of short dorsal teeth, with single cuspidate seta among each lateral pair. Eye small, suboval; inferior antennal notch relatively large, open. Antenna 1 peduncle 1 with posterior marginal robust setae in distal half, article 2 slightly shorter than article 1; flagellum relatively long, with 31 articles; accessory flagellum 4-articulated. Antenna 2 flagellum short, with 14 setose articles. Mandible, comb row with 10–12+ raker setae; palp article 3 setose. Maxilla 1, inner plate with 14 marginal setae. Maxilla 2, inner plate with submarginal facial row of setae. Maxilliped, inner plate with 4 apical teeth-like setae; outer plate medium, 3/5 of palp article 2 length. Coxa 1 medium, distally broad, deeper than wide, with rounded lower margin. Coxa 4 medium, deeper than broad. Propodus of pereopod 1 relatively small, shorter than carpus, not broadened distally; palm regularly oblique; dactylus curved, slightly shorter than palm. Pereopod 2 carpus, posterior lobe broad; propodus large, longer than deep, palm convex and oblique, longer than posterior margin, with a row of strong long robust setae; dactylus thin, curved, with few long outer marginal setae. Pereopod 3 similar to pereopod 4; dactylus long, 0.7 of article 6 length. Pereopods 5–7, basis dissimilar, broadened from 5 to 7. Uropod 1, peduncle short, rami with 4–5 robust setae marginally. Uropod 3, outer ramus relatively long, margins subparallel, each with 3–4 groups of robust setae; terminal article very small. Telson lobes with acute tips, with single distolateral and medial strong cuspidate setae each. Coxal gills large, broadly saclike, gills 5 and 6 similar in size, distinctly smaller than 2–4. Type material. Holotype female, 11.5 mm, 54398/Cr-2426, slope of western Kamchatka Peninsula, Sea of Okhotsk, Far East of ... |
