A small cave that opens on the eastern slope of Mt. Vardousia at the side of the dirt road that links Athanasios Diakos to Dafni. The cave is about 20-30 m long and consists of a single room. Di Russo et al. 2014 mention another unnamed cave at Mount Vardousia (1,110m asl) where Dolichopoda lustriae was collected by P. M. Giachino and D. Vailati on 10.VI.2005. This is probably the same cave. The location and the sort description of Dafni cave provided by Alexiou et al. 2014, matches with the cave of Athanasios Diakos, described by Petrochilou 1992.
