説明

The harvestman species, Parabeloniscus caudatus Suzuki, 1973 (Opiliones, Epedanidae), has been recorded from Okinawa-jima Island, Miyagi-jima Island and Ikei-jima Island of the central Ryukyus, Japan. This species is considered to be highly dependent on cave environments (Shimojana 1978; 1979). Our survey found new habitats of P. caudatus from Amami-oshima, Tokunoshima and Okinawa-jima islands in the central Ryukyus, Japan. An unidentified Parabeloniscus species has previously been reported from Amami-oshima and Tokunoshima islands, and our study confirmed for the first time that P. caudatus is distributed on these islands. We also found the species under stones in the forests outside caves. A previous study reported the presence of eyeless individuals (Shimojana 1979). The current study also found eyeless individuals from two separate caves.
