Dear Ivan,
Many thanks for your comment and suggestions! I believe that you are probably right especially that in this cave only two species of this genus were noted till now: R. mehelei and R. ferrumequinum. I also thought that this can be R. mehelei but to be sure I sent this picture (and some other with profile POV) to my friend specializing in Chiroptera and till now I am waiting for his confirmation.
I hope to receive it after weekend so it will be nice to see if we have right :)
Once again many thanks for visit and ID!
Best greetings and also have a very nice (and sunny) weekend!
