The paper presents descriptions of three new opilionid species: Egaenus turkmenicus sp.n. ( ?? ), Phalangium kopetdaghensis sp.n. ( ?? ) and Graecophalangium karakalensis sp.n. ( ?? ) from Turkmenistan. All species are diagnosed, described, figured, and their distributions are mapped.
Distributional data for the millipedes occurring in the Ryukyu Archipelago and adjacent islets (Senkaku and Daito Groups) are summarized based on an extensive literature survey. There are at least 58 species and one subspecies of millipedes known from the Ryukyu Archipelago (50 of these are native and 8 introduced), 5 species in the Senkaku Group, and 7 species in the Daito Group. Of these, the greatest diversity of indigenous millipede species (32 species) occurs in Okinawa-jima Island. Our results contribute to the knowledge of the millipede fauna in the region beyond the limited account presented in the previous reviews. The results also suggest that large portions of the Ryukyu Archipelago have been poorly sampled, and that further collections would considerably improve the present inventory.
