A New Species

A new scincid lizard, Plestiodon takarai sp. nov., is described from the Senkaku Group, Ryukyu Archipelago, Japan. The Plestiodon lizards in this island group have previously been identified as P. elegans because they all exhibit a patch of enlarged and irregularly arranged scales on the posterior surface of their femurs. However, detailed molecular analyses revealed that the Senkaku population, although closely related to P. elegans and other species in the P. latiscutatus species group, is substantially diverged from all other recognized species. Furthermore, although the Senkaku population largely exhibits the characteristic morphological features of this species group, it can be differentiated from all recognized species by the scutellation and hatchling tail coloration. The biogeographical and conservation implications of these findings are briefly discussed.

A New Species

We describe Expanathura monile sp. nov. from Iriomote Island, Okinawa, Japan, northwestern Pacific. This species resembles E. collaris, E. macronesia, and E. haddae in having very broad uropodal rami, a broad telson, and a moderately shortened pleopod 1 endopod, but differs from these three species in the female having (1) the head with a dorsal V-shaped band of brown pigmentation, (2) the antennular flagellum with 3–4 articles, (3) antennal peduncular article 2 with an outer triangular projection, (4) the uropodal endopod longer than wide, (5) the uropodal exopod with an acute triangular projection, (6) an oval telson, and (7) the posterolateral setae on the telson similar in length. We present a revised key to known species in the genus Expanathura and briefly discuss the male polymorphism observed in E. monile.

A New Species

A new hydromedusa belonging to the order Limnomedusae is reported from the Ryukyu Archipelago, southern Japan. Olindias deigosp. nov. can be distinguished from other Olindiidae species by the number and color of tentacles. Mature medusae of O. deigosp. nov. were collected to observe the life history, including polyp (hydroid) and medusa formation. A comparative table of the primary diagnostic characters of the genus is provided.

A New Species

The Ryukyu Archipelago of Japan is a recognized global biodiversity hotspot with many endemic species. However, our knowledge of the termite fauna of the Ryukyu Archipelago is insufficient. Here, we report a new species of endemic drywood termite (Kalotermitidae) from the Ryukyu Archipelago. Our systematic study of the genus Neotermes (Isoptera: Kalotermitidae) from the Ryukyu–Taiwan Island arc using molecular and morphological methods found that N. koshunensis had also been composed of a second cryptic species, N. sugioi sp. nov. These two species are distributed allopatrically in the Ryukyu–Taiwan Island arc, with the former only in Taiwan and the latter only in the Ryukyu Archipelago. Our discovery of a new drywood termite species from the Ryukyu Archipelago suggests that both morphological and molecular assessments of the species now considered to be distributed widely in the Ryukyu–Taiwan Island arc are needed to clarify the termite fauna of the Ryukyu Archipelago.
