Six species of caridean shrimps from four families are recorded from Japanese waters for the first time on the basis of material from the Ryukyu Islands and its adjacent waters, collected during research cruises of the T/RV “Toyoshio-maru” of Faculty of Applied Biological Science, Hiroshima University: two species of Crangonidae, Lissosabinea unispinosa Komai, 2006 and Pseudopontophilus serratus Komai, 2004; one species of Oplophoridae, Systellaspis pellucida (Filhol, 1885); one species of Pandalidae, Calipandalus elachys Komai & Chan, 2003; and two species of Pasiphaeidae, Pasiphaea debitusae Hayashi, 1999 and P. gracilis Hayashi, 1999. Of them, L. unispinosa, Pseudopontophilus serratus, Pasiphaea debitusae and P. gracilis are heretofore known from the South-West Pacific localities, and then the geographical ranges of these four species are greatly extended to the north and west. Illustrations and/or colour images are provided for each species to supplement previous descriptions and to give evidence for identification.

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.

Based on two specimens collected in the Antarctic deep-sea (4928 m) the adult female and male of the genusPseudolamprops Gamô, 1989 are described for the first time. A new combination is proposed, Pseudolamprops profundus(Reyss, 1978) comb. nov., and several new records from the North Atlantic and Antarctica are provided. The diagnosis of Pseudolamprops is revised on the account of the new material available.

Two species of the chirostyloid families Sternostylidae and Eumunididae, Sternostylus investigatoris (Alcock & Anderson, 1899) and Eumunida balteipes n. sp., are reported on the basis of material collected from deep waters off Kume Island, Ryukyu Islands, southwestern Japan. Sternostylus investigatoris is recorded for the first time and is the second species of the genus from Japanese waters. Eumunida balteipes n. sp. is morphologically closest to E. sternomaculata de Saint Laurent & Macpherson, 1990, but the armature of the thoracic sternite 3 and P1 palm distinguishes the two species.

Three species of the pagurid hermit crab genus Catapaguroides A. Milne-Edwards & Bouvier, 1892, all from Japanese waters, are reported. Catapaguroides fragilis (Melin, 1939) is redescribed on the basis of the holotype and additional material from southern Japan. Diagnostic characters of this poorly known species are fully assessed. Two new species, C. bythos and C. rubromaculatus, are described and illustrated on the basis of material from upper bathyal depths off the Ryukyu Islands. Catapaguroides rubromaculatus n. sp. resembles C. fragilis and C. hirsutus Komai & Rahayu, 2013, but the characteristic shape of the ocular peduncle and the elongate male right sexual tube with an anteriorly directed distal portion readily separate C. rubromaculatus n. sp. from the latter two congeners. Catapaguroides bythos n. sp. appears close to C. mortenseni de Saint Laurent, 1968 and C. pectinipes (Lewinsohn, 1969), but the different armature of the chelipeds distinguishes C. bythos n. sp. from the latter two allies. Catapaguroides is now represented by 30 species.

Five species of the genus Polyonyx Stimpson, 1858 are reported from southern Japan, the Philippines, Singapore, and Peninsular Malaysia. All of them belong to the P. sinensis group, which is morphologically defined by having the dactyli of the ambulatory legs each with the dorsal claw being much smaller than the ventral claw. Two species are described as new to science, one each from Peninsular Malaysia and the Ryukyu Islands in Japan, and their affinities are discussed. Polyonyx boucheti Osawa, 2007, P. heok Osawa & Ng, 2016, and P. thai Werding, 2001, are also newly reported from southern Japan, the Philippines, and Singapore. A key to the Indo-West Pacific species of the P. sinensis group is provided.

Munida michaeli, a new species of deep-sea squat lobster (Munididae), is described and illustrated on the basis of a single male specimen collected off Okinawa Island, Ryukyu Islands, Japan, at depths of 641-650 m. It closely resemblesM. sacksiMacpherson, 1993 known with certainty only from the Philippines, but different spination of the carapace dorsum and the greatly reduced armature of the flexor margins of the ambulatory dactyli distinguish the new species from the latter. With the addition of the present new species, 41 species ofMunidaLeach, 1820 are now known from Japanese waters.

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.

A New Species

The present study focuses on shrimps belonging to the genus Lysmata Risso, 1816, collected from Madagascar during the Atimo Vatae expedition carried out in 2010. Lysmata malagasy sp. nov. is a new species belonging to the clade named “long accessory ramous” or “cosmopolitan” in previous phylogenetic studies. The new species can be distinguished from the only two other representatives of this group in the Indo-west Pacific, L. ternatensis De Man, 1902, and L. trisetacea (Heller, 1861), by the accessory ramus of the lateral antennular flagellum consisting of four elongated articles. Lysmata lipkei Okuno & Fiedler, 2010 is reported here from Madagascar with a remarkable extension of its known range after its original description from Japan. This species has also been reported from Singapore and, as alien species, from Brazil. Lastly, L. kuekenthali De Man, 1902 known from numerous localities in the Indo-West Pacific biogeographic area, is reported for the first time from Madagascar. Results of the present morphological and molecular analyses suggest that L. hochi Baeza & Anker, 2008 from the Caribbean Sea is a synonym of the Indo-West Pacific L. kuekenthali, and thus the latter species is alien in the western Atlantic.
