Material examined SVALBARD • 7 specs; Kongsfjorden; ID 264 to 265, slide No. 2140 to 2141, 3039, 3217 to 3218; ELTE. Description Short description of fixed specimens: MEASUREMENTS. Body length 11 – 16 mm, segment number 55 – 66, 650 – 800 μm wide at clitellum. CHAETAE. Chaetal formula: 3,2 – 2: 3 (2) – 2. Preclitellar chaetae 60 – 85 μm × 7 μm ventrally, 55 – 58 μm × 6 μm laterally, postclitellar chaetae 75 – 85 μm × 6 μm ventrally, and 58 – 75 μm × 6 μm laterally. DORSAL VESSEL. From XIII – XIV. SPERM SACS. Large sperm sacs, located in X – XI. SPERM FUNNEL. 376 μm long, about 3 × as long as wide, fixed. Sperm duct about the same wide in all length (20 – 25 μm wide). MALE COPULATORY ORGANS. Male glands multiple: one larger rounded primary bulb (diameter 75 – 85 μm) and numerous smaller glands. SPERMATHECAE. Ectal duct of spermatheca 62 – 90 μm long with large glands around orifice of duct. Ampulla spherical (diameter 120 – 140 μm) with one diverticulum (about 270 μm long), or 2 – 3 smaller diverticula (80 – 110 μm long). Additional specimens would be required for accurate description.
