The present report deals with caridean shrimps from the families Hippolytidae (7 species) and Barbouriidae (1 species)collected during the KUMEJIMA 2009 expedition in the Ryukyu Islands. The deep-water hippolytid Gelastreutescrosnieri Bruce, 1990 is recorded from Kumejima based on a single female specimen, representing a considerable rangeextension of this species from New Caledonia to Japan. The opportunity is also taken to record and illustrate the firstknown male specimen of G. crosnieri, collected during the SANTO 2006 expedition off West Mavéa Island, Vanuatu. Thecolour pattern of G. crosnieri is shown for the first time. The Kumejima and Vanuatu specimens present noticeabledifferences in both morphology and colouration, but appear to be conspecific based on comparison of the barcoding geneCOI sequences. The recently described Lysmata lipkei Okuno & Fielder, 2010 is recorded for the second time, however,not representing a significant range extension of this species. The other species reported are Saron marmoratus (Olivier,1811), Saron neglectus De Man, 1902, Thinora maldivensis (Borradaile, 1915), Thor amboinensis (De Man, 1888), Tozeuma armatum Paul’son, 1875 (Hippolytidae), and Parhippolyte misticia (Clark, 1989) (Barbouriidae).

In this paper, we revised the physopeltine genus Physopelta Amyot & Serville, 1843 (Hemiptera: Heteroptera: Largidae) from Japan, Korea, and Taiwan. Five species were recognized and diagnosed, including two new species, Ph. (Neophysopelta) lutaspidata sp. nov. from northern and central Taiwan and Ph. (N.) fusciscutellata sp. nov. from the Ryukyu Islands, Japan and Taiwan, and three known species, Ph. (N.) gutta gutta (Burmeister, 1834), Ph. (N.) parviceps Blöte, 1931, and Ph. (N.) quadriguttata Bergroth, 1894. Physopelta (Neophysopelta) fusciscutellata sp. nov., was previously regarded as either of the two species, Ph. (N.) cincticollis Stål, 1863 and Ph. (N.) parviceps, for populations from Taiwan. Previous records of Ph. (N.) cincticollis from Japan proper and Korea, and Ph. (N.) slanbuschii (Fabricius, 1787) from the Ryukyu Islands were considered as misidentifications of Ph. parviceps. A key to facilitate the identification of the five species known in Japan, Korea, and Taiwan is provided. Additionally, Ph. (N.) parviceps is recorded from China (Guangdong Province and Zhejiang Province) for the first time.

We re-examined the taxonomic status of plants treated as Sedum formosanum (Crassulaceae) from Miyako-jima Island of the Ryukyu Islands, Japan, using morphological comparison and molecular phylogenetic analyses with related species. In morphology, plants from Miyako-jima Island bore a close resemblance to the other plants of S. formosanum, but differed in being perennial, polycarpic, and having lateral axillary branches. Molecular analyses based on ITS of nrDNA and six regions of cpDNA sequencing indicated that the Miyako-jima plants formed a distinct subclade. This subclade was part of a polytomy with three other subclades comprising nine taxa endemic to Taiwan and S. formosanum from other areas, including the type locality. Therefore, we propose and describe the Miyako-jima plants as a new subspecies, Sedum formosanum subsp. miyakojimense.

The Lepidoptera fauna of the island of Flores (Lesser Sunda Archipelago, Indonesia) shares a large proportion of endemic species, which may reach 80–100% in several groups (Zolotuhin & Witt 2005; Nässig et al. 2009; Zolotuhin 2009; Nässig & Bouyer 2010; Yakovlev 2015; Spitsyn & Potapov 2020; Spitsyn & Bolotov 2020). A plethora of new species was described from this island during the last 15 years, e.g. the tiger moth Spilarctia mikeli Bolotov, Kondakov & Spitsyn, 2018 (Zolotuhin & Witt 2005; Yakovlev 2006; Spitsyn & Bolotov 2020a, b, c). This species was described based on a single female specimen collected in West Flores (Bolotov et al. 2018). In the present paper, we describe the male of Spilarctia mikeli for the first time, and illustrate variability of marking patterns of both the male and the female of this species.

Two lace bug genera, Baeochila Drake & Poor, 1937 and Idiocysta China, 1930 (Hemiptera: Heteroptera: Tingidae) are recorded from Japan for the first time, and two new species, B. horvathi sp. nov. and I. takarai sp. nov., are described. The former was collected from the vines of Hedera rhombea (Miq.) Bean (Araliaceae) and the bark of Trachycarpus fortunei (Hook.) H.Wendl. (Arecaceae) in suburbanized areas of Honshu, Shikoku and Kyushu, and the latter was collected from the leaves of Freycinetia formosana Hemsl. (Pandanaceae) in the laurilignosa ecosystem of the Ryukyu Islands. The distribution ranges and host plant relationships of the two new species are discussed. Keys to all species of the two genera and photographs of living individuals for the new species are also presented.

Two antipatharian-associated species of the pontoniine shrimp genus Cuapetes Clark, C. lanceolatus sp. nov. and C.nilandensis (Borradaile), are reported from the Ryukyu Islands, Japan. The new species appears closest to C. akiensis(Kubo) and C. calmani (Tattersall), but differs considerably from the latter two species in the shape of the rostrum and thelength of upper antennular flagellum. Cuapetes nilandensis, the type species of the genus, is recorded from Japanese waters for the first time.

There are few records of beetles of the family Elateridae from Tanegashima Island, in the Ôsumi Islands, in the Ryukyu Islands, Japan, and the elaterid fauna of this island has not been reviewed. We examined newly collected specimens and reviewed the previous records from the island. In field work and from a colleague’s collection, we found 27 species, of which 13 were recorded for the first time on the island. As result 43 species are confirmed from this island and a checklist of all elaterid species from Tanegashima Island is provided.

The epigean spiders of the genus Cybaeus L. Koch, 1868 are known to have diversified in western North America and the Japanese Archipelago. To date, ~80 species of Cybaeus are known from Japan, but they have not previously been recorded from the Ryukyu Islands that harbour a diversity of endemic species. Here we describe eight new species of Cybaeus from the Ryukyu Islands, extending the range of Cybaeus southward to the central Ryukyus. Both sexes of each of the new species are described, and their phylogenetic relationships are estimated using nuclear and mitochondrial gene markers. Although Cybaeus okumurai, sp. nov. and C. kumadori, sp. nov. possess genital features that are common in the other Japanese congeners, the other six species (C. yakushimensis, sp. nov., C. kodama, sp. nov., C. amamiensis, sp. nov., C. aikana, sp. nov., C. tokunoshimensis, sp. nov., and C. hikidai, sp. nov.) are characterised by an elongated embolus and tubular spermathecae. These unique genital characteristics and the phylogeny recovered here suggest that these features evolved independently among the Japanese and Ryukyu Cybaeus species. Phylogenetic analyses highlight an unusual biogeographical pattern in which C. yakushimensis and C. kodama endemic to Yakushima Island in the northern Ryukyus are related to species distributed in the central Ryukyus. In contrast, our phylogeny suggests that C. okumurai from Tanegashima Island in the northern Ryukyus is sister to C. ashikitaensis (Komatsu, 1968), distributed in Kyushu of the Japanese Archipelago. The retreat constructs and sympatric distribution of Cybaeus found among the Ryukyus are also briefly discussed. ZooBank: urn:lsid:zoobank.org:pub:640D15AA-17F4-48EE-88B4-485CFF8FCD60

This paper focuses on the writings of Hino Ashihei (1907-1960) about Okinawa, a corpus of twelve works composed over a period of sixteen years that were inspired by three visits to the Ryūkyū Islands. Hino is best known as a writer of war novels, but these twelve works have received almost no attention, partly because they are not considered Okinawan literature since Hino was a native of Kyūshū. The aim of this article is to show that Okinawa is not merely a setting for these neglected writings but rather a complex representation that incorporates the author’s gaze, his stance toward the region, and a topography of power. Moreover, this representation evolved over time to produce an array of at times contrasting images of Okinawa, whether as a tropical paradise, the shield of the nation, or a symbol of its occupation. On the other hand, the narrator’s stance, which is characterised at first by the strength and assertiveness of a first-person narrator, underwent a progressive disengagement that was intended, by this article’s interpretation, to introduce greater objectivity into Hino’s prose.

Abstract Telphusa austeniana Wood-Mason, 1871 is a poorly known potamid crab described from a single female specimen from Meghalaya state, northeastern India, and its position in Tiwaripotamon Bott, 1970 has been questioned. Its systematic position is now clarified based on the examination of the female holotype and a male specimen recently collected from a cave near the type locality. The species is transferred from Tiwaripotamon to a new genus, Krishnamongen. nov. on the basis of the differences in the structures of the epigastric cristae, male pleon, male sixth pleonal somite, male telson, gonopods, and vulvae. The geographic distributions of the two genera are some 1,000 km apart. The new genus has affinities with Doimon Yeo & Ng, 2007, and Indochinamon Yeo & Ng, 2007, but can be distinguished mainly by its extremely slender and elongated ambulatory legs. While Krishnamon austenianum (Wood-Mason, 1871) comb. nov. is now recorded from limestone caves, it does not, however, possess the troglomorphic features of an obligate troglobite.
