FIGURES 30–36. Claw index in populations of Agrenia bidenticulata complex: 30–32, distal half of Leg III in specimens from S Buryatia (Boreal zone of East Siberia) (30), Putorana Plateau (Subarctic zone of East Siberia) (31), and Franz Josef Land (High Arctic) (32), 33, relationship of Claw index, ratio Tibiotarsus length/outer edge of claw, and size of animal, plotted for 141 individuals, open circles—Baikal populations, plain circles—other populations, diameter of a circle is representative of Tibiotarsus length (smaller circles: juveniles, large circles: adults or large juveniles); 34–36, plots of Claw index against length of tibiotarsus 3 in individuals from all localities under study (34), in Arctic (35), and Boreal mountain populations (36). In figs 35 and 36 only the specimens with the length of tibiotarsi 3> 0.2 mm are plotted. tun—tunica.
