Figure 2. Richtersius coronifer (A–D) and Diaforobiotus islandicus (E–J). A, buccal–pharyngeal apparatus, with enlarged terminal portion (arrow) of the buccal tube (neotype) (Norway). B, buccal–pharyngeal apparatus (population from northern Italy 1). C, buccal–pharyngeal apparatus, with the dorsal thickening in the anterior portion of the buccal tube (arrow) (Sweden). D, buccal–pharyngeal apparatus (Greenland). E, F, lateral view of the claws on the second leg at different focus levels. The evident stalk system (arrow) and cuticular pores (arrowhead) on the leg are visible (Norway). G, buccal–pharyngeal apparatus (ventral view), with some strong, scattered round teeth in the buccal armature (arrow) (Italy). H, buccal–pharyngeal apparatus (dorsal view), with the large tooth (arrow) on the internal surface of the buccal tube (Norway). I, buccal–pharyngeal apparatus (lateral view) (Greenland). J, anterior portion of the buccal tube (enlargement of I), with the large tooth on internal surface (arrowhead) and the dorsal thickening (arrow) (Greenland). A, B, D–F, H: phase contrast; C, G, I, J: differential interference contrast. Scale bars = 10 µm.
