304587BCFFC23766FE4C96BE367BFA7A.taxon	etymology	Etymology: The species is named in honour of Vartan Zh. Ambardzumyan (Yerevan, Armenia), who helped to arrange an expedition, during which the type series was collected.	en	Marusik, Yuri M., Zonstein, Sergei L.

304587BCFFC23766FE4C96BE367BFA7A.taxon	diagnosis	Diagnosis: The structure of the spermathecae in the new species somewhat resembles that in R. zaitzevi (Charitonov, 1948), and is more similar to their structure in R. niedermeyeri (Brignoli, 1972) and R. vonwicki Zonstein, 2000. The new species can be distinguished from all three in the shape of their three-head receptacular branches arising from a narrow common base (Figs 6, 7 cf. Figs 8 – 10).	en	Marusik, Yuri M., Zonstein, Sergei L. (2021): Description of Raveniola ambardzumyani n. sp. from Armenia (Araneae: Nemesiidae).

304587BCFFC23766FE4C96BE367BFA7A.taxon	discussion	Comments: In the holotype, the PME pair is completely lacking, and the spider is in fact six-eyed, while the paratype juvenile has a normally looking pair of small PME (Fig. 4 cf. Fig. 5).	en	Marusik, Yuri M., Zonstein, Sergei L. (2021): Description of Raveniola ambardzumyani n. sp. from Armenia (Araneae: Nemesiidae).

304587BCFFC23766FE4C96BE367BFA7A.taxon	biology_ecology	Ecology: The type series was collected in the midland mountain zone, on open clay slope with embedded small stones (Figs 13 – 17). That appears to be unusual for Raveniola occurring in the Caucasus (the previously known Caucasian species were collected from more mesophilic biotopes; see Zonstein et al. 2018). Spiders were found dwelling in cavities among stones. This slope was inhabited by small pholcids, belonging to a seemingly new to science species of Spermophora Hentz, 1841. They also were found dwelling along those cavities.	en	Marusik, Yuri M., Zonstein, Sergei L. (2021): Description of Raveniola ambardzumyani n. sp. from Armenia (Araneae: Nemesiidae).
