Korykeio Antro is the cave from where the first cave animals of Greece have been recorded. From the samples collected by Th. J. Krüper, Brunner Von Wattenwyl (1861) identified the cave cricket Rhaphidophora cavicola -a record assigned recently to Troglophilus zoia (Di Russo et al. 2014)- and Schaum (1962) described a new ground-beetle species (Anophthalmus Krueperi = Duvalius krueperi), the first obligate cave-dwelling species recorded in Greece.
