A new pill millipede species, Hyleoglomeris magy sp. nov., is described from Okinawa and adjacent islands, Ryukyu Archipelago, Japan. The new species is mainly characterized by its large body (maximum length: 12.1mm) and general light yellowish-brown coloration marked with pairs of blackish spots. The general appearance of the new species resembles that of Hyleoglomeris hongkhraiensis Golovatch & Panha 2015, but can be distinguished from this species by the number of striae on the thoracic shield (typically 8–10, with 3 or 4 crossing the dorsum, vs 7 or 8 in total with 4 or 5 crossing the dorsum) and the shape of the telopod (femur strongly bulged distally, vs not bulged). An identification key to all five species of Hyleoglomeris known to occur in the Ryukyu Archipelago is also provided.

We observed egg-brooding behavior in two Japanese millipedes, Eutrichodesmus elegans (Miyoshi, 1956) (Polydesmida: Haplodesmidae) and Cryptocorypha sp. (Pyrgodesmidae), under field conditions. In the former, females remained curling the body around the soil-made mound-like egg-chamber (containing eggs) constructed on dead leaves in the litter. In the latter, a female brooded an egg-mass under the bark of a decaying fallen log.

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.
