Diagnosis

In the shape of the bulb this species resembles R. marusiki sp. nov. and R. zaitzevi . It differs from both species by a noticeably longer apical segment of the PLS ( Fig. 67 View Figs 59–67 ; cf. Fig. 66 View Figs 59–67 ). The males can be distinguished in having a slightly longer embolus lacking dentate keels ( Figs 195–196 View Figs 189–197 ; cf. Figs 191– 194 View Figs 189–197 ) and a more slender palpal tibia ( Fig. 163 View Figs 161–164 ; cf. Figs 161–162 View Figs 161–164 ). The female of R. vonwicki differs from those in the same species group in having longer spermathecae with stalked, not sessile, lateral receptacles ( Fig. 210 View Figs 204–212 ; cf. Figs 208–209, 211–212 View Figs 204–212 ).
