| Summary: | Tenuibiotus zandrae sp. nov. urn:lsid:zoobank.org:act: 99D6163D-E8E6-4223-B975-F68AA2268304 Figs 10–19 Etymology We take great pleasure in dedicating this new species to the friend of the first and third authors. Zandra Maria Skandrup Sigvardt, who recently completed her PhD studies working on crustaceans (Section of Biosystematics) at the Natural History Museum of Denmark in Copenhagen. Material examined 62 animals (including 18 simplex) and 171 eggs. Specimens mounted on microscope slides in Hoyer’s medium (49 animals + 161 eggs), fixed on SEM stubs (including two extracted buccal apparatuses) (10 +10), and processed for DNA sequencing (3 +0). Holotype GREENLAND • Disko Island, Østerlien; 69°15′17″ N, 53°30′46″ W; 30 m a.s.l.; sample of moss collected from the rock in arctic tundra; IZiBB, slide GL.011.17. Paratypes GREENLAND • 58 paratypes; same collection data as for holotype; IZiBB, slides GL.011.08 to 011.09, 011.16 to 011.19, 011.22 to 011.23, 011.27 to 011.28, SEM stubs GL.012.06 to 012.07, 012.13 • 171 eggs; same collection data as for holotype; IZiBB, slides GL.011.10 to 011.15, 011.20 to 011.21, 011.24 to 011.26, 011.29, SEM stub GL.12.13. Description Animals (measurements and statistics in Table 4) Body transparent in juveniles and whitish in adults, after fixation in Hoyer’s medium transparent (Fig. 10). Eyes present in specimens mounted in Hoyer’s medium. Body cuticle without pores but covered with fine granulation including ventral side of the body and all legs (Figs 11–13). Granulation is distributed uniformly on the body (Fig. 11 A–B, E) but sometimes, especially in larger specimens, random patches without granulation are present on the body cuticle (Fig. 11 C–D, F). Patches of dense granulation composed of cushions with aggregated granules present on all legs (Figs 12–13). A patch of clearly visible granulation, is present on the external surface of legs I–III just below the claws (Figs 12A, 13A). A pulvinus is absent on the internal surface of legs I–III, whereas a patch of dense granulation ... |
