Two genera of Euconnus-like Stenichnini are reported to occur in Japan: Himaloconnus Franz, 1979 and Nogunius gen. n. Specimens of Himaloconnus collected on islands of the Ryukyu archipelago are identified as H. klapperichianus (Franz), previously known to inhabit Taiwan, but morphological differences were found among disjunctive populations and in consequence three new subspecies are proposed: H. klapperichianus yaeyamanus ssp. n. (Yaeyama Islands), H. klapperichianus amamianus ssp. n. (Amami-Ôshima), and H. klapperichianus okinawanus ssp. n. (Okinawa Island). Morphological structures of Japanese Himaloconnus are illustrated in detail and the diagnosis of this genus is emended, to exclude variable characters. Nogunius gen. n. is established to accommodate four species known only from Japan: N. sokani sp. n. (Okinawa Island), N. aogashimanus sp. n. (Aogashima, Izu Islands), N. kerri sp. n. (Ishigaki Island), and N. fukuuzanus sp. n. (Okinawa Island). Identification key to Japanese genera of Stenichnini is updated.

The genus Nogunius Jałoszyński was proposed to accommodate four species distributed exclusively in Japan: N. sokani Jałoszyński (Okinawa Island), N. aogashimanus Jałoszyński (Aogashima, Izu Islands), N. kerri Jałoszyński (Ishigaki Island), and N. fukuuzanus Jałoszyński (Okinawa Island). A female of an undescribed species collected in mainland Japan, on Shikoku, was also recorded. In the present paper we provide evidence that this interesting and apparently very rare genus occurs also on Kyushu. Nogunius sagaensis sp. n. is described, based on a single male collected in Saga Prefecture, NW Kyushu. Diagnostic characters of all nominal species are compared, and a distribution of Nogunius is summarized.

Crown-of-thorns starfish, Acanthaster planci (COTS), are common in coral reefs of Indo-Pacific Ocean. Since they are highly fecund predators of corals, periodic outbreaks of COTS cause substantial loss of healthy coral reefs. Using complete mitochondrial DNA sequences, we here examined how COTS outbreaks in the Ryukyu Archipelago, Japan are reflected by the profile of their population genetics. Population genetics of the blue starfish, Linckia laevigata, which lives in the Ryukyu Archipelago, but not break out and the northern Pacific sea star, Asterias amurensis, which lives in colder seawater around the main Islands of Japan, were also examined as controls. Our results showed that As. amurensis has at least two local populations that diverged approximately 4.7 million years ago (MYA), and no genetic exchanges have occurred between the populations since then. Linckia laevigata shows two major populations in the Ryukyu Archipelago that likely diverged ∼6.8 MYA. The two populations, each comprised of individuals collected from coast of the Okinawa Island and those from the Ishigaki Island, suggest the presence of two cryptic species in the Ryukyu Archipelago. On the other hand, population genetics of COTS showed a profile quite different from those of Asterias and Linckia. At least five lineages of COTS have arisen since their divergence ∼0.7 MYA, and each of the lineages is present at the Okinawa Island, Miyako Island, and Ishigaki Island. These results suggest that COTS have experienced repeated genetic bottlenecks that may be associated with or caused by repeated outbreaks.

M. birmanicus (Kaszab, 1980) is recorded from China (Yunnan) for the first time. M. papillatus Kaszab, 1941 is firstly recorded from Yunnan and Sichuan, China. Two poorly known species, M. aenescens Pic, 1925 and M. vietnamicus Kaszab, 1980 are redescribed. Male of M. atavus (Kaszab, 1960) is described in detail. Misidentifications of M. aenescens Pic. 1925 and M. atavus (Kaszab, 1960) in previous works are corrected. Six species groups are proposed. A species catalog, identification key and distributional maps for the genus are given.

Morphological differences between the type specimen ofC. hystrixand the type specimens of its two junior synonyms,Ephemerella cascadiaAllen and Edmunds, 1961, andE. spinosaMayo, 1952, are detailed.

The carnivorous plant Pinguicula filifolia occurs in western Cuba and shows a restricted distribution due to habitat specificity associated with poor wet soils. Its populations are distributed mainly in south Pinar del Río (Cuba) and in Isla de la Juventud. Plants from one isolated location in NW Pinar del Río shows morphological differences with respect to the rest of the known populations observed in nature. Subsequent detailed morphological analysis of specimens led to the description of Pinguicula filifolia subsp. alba as a new subspecies. It differs from the typical subspecies in several reproductive traits involving flower, fruit and seed characters and is so far known only from the type locality.

Gnathia maculosa sp. nov. is described from males reared in a laboratory from larvae that were collected as ectoparasites on elasmobranchs, caught off Okinawa Island in the Ryukyu Archipelago, southwestern Japan. The species is most similar to G. trimaculata but it is distinguished from G. trimaculata by deeper and narrower dorsal sulcus, a narrower body, and the wider pylopod. Gnathia trimaculata, previously recorded from Great Barrier Reef, Australia, was also collected from elasmobranchs caught off Okinawa Island. The record of G. trimaculata from Okinawa indicates a wide range of the distribution of the gnathiids inhabiting elasmobranchs.
