We describe two new species of the millipede genus Riukiaria from two islands of the Ryukyu Archipelago: R. maculata sp. n. from Tane-ga-shima, northern Ryukyus, and R. mundyi sp. n. from Yonaguni-jima, the southwesternmost member of the Yaeyama Island Group. Both species show the simple forceps-like male gonopod structure typical for the genus, but they are readily distinguishable from other members by their unique color patterns. We have also compiled a list of species in the genus described up to now.

Sexannulate Orobdella leech, Orobdella ijimai, is redescribed based on newly collected specimens from the type locality, Nikko, Tochigi Pref., Japan, since this species was originally described based on limited number of characters. In addition, two new sexannulate species, Orobdella dolichopharynx sp. nov. from Amamioshima Island in the Ryukyu Archipelago, Japan, and Orobdella shimadae sp. nov. from Okinawajima Island also in the Ryukyu Archipelago, are described. They resemble O. ijimai in the annulation of mid-body somites, but they differ from the latter in the annulation of somite VIII, position of gonopores, the lack of gastropore, the length of pharynx, the shape of gastroporal duct, and the morphology of male genital organ. Two new Orobdella species differ from each other in the annulation of somite VII, the position of gonopores, and the shape of gastroporal duct. In accordance with the two new species, the diagnosis of Orobdella is slightly emended.

Holotype Male

Ten species of Cephennomicrus are currently known to occur in Japan, predominantly in the Ryūkyū Archipelago. These extremely small beetles (adults of Japanese species do not exceed 1.2 mm) are rarely collected, and their true diversity may be in fact much greater. Two more species are described in the present study: C. aji sp. n. inhabiting Okinawa island, and C. ushimanus sp. n. found on Amami Ôshima island. Cephennomicrus aji has the smallest adults of all Japanese Scydmaeninae; the holotype male measures merely 0.66 mm of body length. The distribution of Japanese Cephennomicrus species is summarized, with the aedeagus of each species illustrated on the distribution map, to facilitate identifications and further study on this broadly distributed but poorly known cephenniine genus.

Two New Species

To date, three nominal species of the eutheiine genus Paraneseuthia were known to occur in Japan (in Honshū and Kyūshū). A female of an undescribed species was also recorded from Iriomote Island of the Ryūkyū Archipelago. Two new species are here added to this list: P. ishigakianas p. n. (Ishigaki Is.) and P. ehimensis sp. n. (Shikoku). Paraneseuthia holzneri (Franz), described on the basis of a single male with erected and distorted aedeagus, is recorded from a new locality and its aedeagus is illustrated.

First Time

The Japanese Milichiidae are taxonomically revised with four newly recorded genera (Milichia, Madiza, Neophyllomyza, and Leptometopa). Two new species of Milichia and Neophyllomyza are described: Milichia yafusoae sp. nov. was discovered on guano of the Southeast Asian long-fingered bat (Mineopterus fuscus Bonhote) in a limestone cave of Okinawa Island, Ryukyu Archipelago; Neophyllomyza nishidai sp. nov. was collected from flowers of Aristolochia debilis Siebold et Zucc. (Aristolochiacea) which have trap-and-release mechanisms for using flies as pollinators in Honshu. Two species, Leptometopa latipes (Meigen) and Madiza glabra (Fallén), are recorded from Japan for the first time. Bionomic remarks for each species and a key to the genera and species of the Japanese Milichiidae are also provided.
