Morphological examination: ZMUC-CRU 6558 (type), Bellsound, Spitsbergen. USNMNH 97T408; Atlantic biological station, St Croix River, New Brunswick, June 20, 1927, male, 4mm. TSZCr17994, Tromsø Museum. 7840.592N 02126.230E (Hinlopen strait, Spitsbergen), 40– 70m. 2.3 C. 21.08.2006 (used for all drawings), female, 7mm. SEM-examination: tubes 104, 112, 134, 144. St. JM 340–346. 7840.592N 02126.230E, 40– 70m. 2.3 C. 21.08.2006 Redescription. We have examined the type material for this species, but it was in poor condition, and was not fit for making slides for illustrations. All illustrations are therefore from our fresh additional material from a site a mere 200 km from the type-locality, also from the archipelago of Spitsbergen. Our examination showed that the types and the fresh material are identical. Morphological redescription based on new material. This redescription is based on a 7 mm long female. Head (Fig. 10): epistome small and rounded, cephalic lobe rounded; eye large (half of head-length),with well-developed ommatidia, bright red in live animals. Antenna 1 (Fig. 6): as long as antenna 2; flagellum 11–12 articulate, with 3 short simple setae on each article; no accessory flagellum. Antenna 2 (Fig. 10): peduncle article 4 slightly longer than article 5; flagellum subequal to article 5, 5-articulate; one short simple seta on ventral side of each article. Labrum (Fig. 10): bilobed, slightly asymmetrical. Mandible (Fig. 10): palp 3-articulate, oval in cross section (see Fig. 19), ... |
