Lepechinella schellenbergi Stephensen, 1944 Figs 10–12 Lepechinella schellenbergi Stephensen, 1944: 18–20, fig 11. Lepechinella arctica – Barnard 1973: 10. — Barnard & Karaman 1991: 268–270. Material examined About 13 specimens of Lepechinella were collected off the west coast of Greenland during the Ingolf Expedition (Stephensen 1944). The specimens were sampled from station 32 at 599 meters depth, 11 Jul. 1895 and station 35 at 682 meters depth 18 Jul. 1895. The position of station 32 was at 66 o 35’N, 56 o 38’W and station 35 was at 65 o 16’N, 55 o 05’W. The in situ temperatures at the collection sites were 3.6– 3.9 o C. The type material of Lepechinella from Greenland is deposited in the collections of Zoological Museum in Copenhagen, Denmark. The examined material was prepared on microscope slides from station 35, from one entire female in addition to the front part of one male and female that probably had been cut during sampling. Lectotype ♀, Ingolf st. 35, on slide (reg.no. ZMUC-CRU-4468) (Figs 10–11). Paralectotypes ♂, Ingolf st. 35, on slide (reg.no. ZMUC-CRU-4469) (Fig. 12). ♀, Ingolf st. 35, on slide (reg.no. ZMUC-CRU-4470) (Fig. 12). 3 paralectotypes, Ingolf st. 32 (reg.no. ZMUC-CRU-8019). 8– 9 paralectotypes, Ingolf st. 35 (reg.no. ZMUC-CRU-8020). Stephensen (1938) translated Schellenberg’s description of Dorbanella sp. as Lepechinella sp. He was then probably unaware that Schellenberg (1926) in a footnote had changed the name from Dorbanella sp. to Lepechinella artica. When describing the specimens from Greenland, Stephensen (1944) assumed that this was the same species as Schellenberg had recorded from Spitzbergen and named it Lepechinella schellenbergi nom. nov. The specimens from Greenland were later assumed to be Lepechinella arctica (Barnard 1973; Barnard & Karaman 1991). Redescription Lectotype Female 6 mm. BODY. Covered mainly dorsally and laterally with setae and spines. The spines, which varied in length, are attached to disc-shaped pegs and varied in size. Peraeon segment 1 with ...
