Diagnosis
This species differs from all other members of the same group by having a gradually tapering and subapically curved embolus ( Fig. 197 View Figs 189–197 ) and by the unusually narrow, laterally inclined spermathecae with small and sessile lateral receptacles ( Figs 211–212 View Figs 204–212 ). In the structure of the embolus, Raveniola niedermeyeri also shows some similarities with a few other congeners, such as R. bellula ( Li & Zonstein, 2015) , R. ferghanensis ( Zonstein, 1984) , R. hebeinica Zhu, Zhang & Zhang, 1999 and R. virgata (Simon, 1891) . However, it can be distinguished from them by having a sharply curved subapical part of the embolus (vs the more gently curved embolus in those Eastern and Central Asian species, Fig. 197 View Figs 189–197 ; cf. Figs 165–166 View Figs 165–170 ; Zonstein & Marusik 2012: fig. 39; Li & Zonstein 2015: figs 3A–C, 5A–C).

Variation
Carapace length in males varies from 4.34 to 5.45; in females from 4.67 to 7.05. In all examined males the embolus has a practically identical shape. The shape of the spermathecae and the dorsal pattern of the abdomen show some variation (cf. Figs 211–212 View Figs 204–212 , 252–253 View Figs 248–253 ).
Distribution
Iran: Alborz, Khorasan and Zagros Mts (Gilan, Mazandaran, Golestan, Razavi Khorasan and Isfahan Provinces). See Fig. 222 View Figure 222 .
Ecology
In the Alborz Mts the spiders were collected predominantly in dense montane broad-leaved forests of the hyrcan type as shown in Figs 236–237 View Figs 236–241 , dominated by Quercus castaneifolia C.A. Mey. Like in most Western Asian congeners, females use cavities under rocks to build short and very simple retreats almost without any silk lining ( Figs 248–251 View Figs 248–253 ). Wandering males were recorded between June and November.
