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 ; cf. Fig. 66 ). The males can be distinguished in having a slightly longer embolus lacking dentate keels ( Figs 195–196 ; cf. Figs 191– 194 ) and a more slender palpal tibia ( Fig. 163 ; cf. Figs 161–162 ). 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 ; cf. Figs 208–209, 211–212 ). Material examined Holotype IRAN : ♂ , Gilan Province , Hishtpar District , E slope of Bogrovdagh Mts , 7 Apr. 1914 , N.S. von Wick leg. ( ZISP 454–914 ).
