Raveniola vonwicki Zonstein, 2000: 49, figs 1–3 (♂♀).
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).
