TABLE 2. Myriotrochus (Oligotrochus) meteorensis spec. nov. Means, standard deviations (in parentheses) and range of wheel parameters of the new species compared to the wheel parameters of M. (O.) clarki (data from Gage & Billett 1986) and M. (O.) vitreus (data from Østergren 1902). D, µm: diameter of wheel, dh, %: diameter of hub expressed as a percentage of total wheel diameter, ns: number of spokes, nsb/ns, %: ratio of branched spokes to spokes, nt: number of teeth, lt, %: length of teeth expressed as a percentage of total wheel diameter, s/t, %: ratio of spokes to teeth.
