Pseudochromis fuligifinis is described from 12 specimens from Verde Island, west coast of Mindoro and Apo Reef in the Philippines. It closely resembles P. elongatus Lubbock from Indonesia and P. striatus Gill, Shao & Chen from the Batanes Islands, Taiwan and the Ryukyu Islands, but differs in various meristic and coloration details. Manonichthys scintilla is described from five specimens from Coron Island and Apo Reef. It differs from congeners in fin shape and live coloration details.

Pacific 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.

First Time

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.

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.

Four olethreutine species, including two new species described herein, are associated with the fruits and seedlings of Rhizophoraceae in the Ryukyu Islands: Cryptophlebia horii Kawabe feeds on Bruguiera gymnorhiza (L.) Lam.; C. amamiana, sp. nov. feeds on Kandelia candel (L.) Druce; C. palustris, sp. nov. feeds on Rhizophora mucronata Lam.; and Eucosma coniogramma Clarke (= Eucosma okubiensis Kawabe, syn. nov, herein newly established as a junior synonym) feeds on Bruguiera gymnorhiza. Adults, larvae, and genitalia are diagnosed and illustrated for each species, and geographic distribution and information on biology are provided. In addition, we discuss Cryptophlebia species associated with mangroves worldwide, host preference, and adaptations to the mangrove environment.

AbstractTwo new species of potamid freshwater crabs of the genus Geothelphusa are described from the Ryukyu Islands in southern Japan. Although both G. shokitai sp. nov. and G. minei sp. nov. are allied to G. candidiensis (type locality Taiwan), they differ from that species and from each other in the form of their carapaces, ambulatory leg proportions, and structure of their male first pleopods.

Two New Species

Two new species of the family Leptochitonidae, Leptochiton pumilus sp. nov. and Terenochiton nomurai sp. nov. are described from the tropical and subtropical shallow waters of the West Pacific. L. pumilus from the Philippines and Papua New Guinea has a net-like sculpture on the shell which is rather rare feature in the genus. In this genus, so far only three species have hitherto been known in the tropical shallow waters, in contrast to more than 130 other extant species which are living in the deep cold waters and high latitudes. T. nomurai from Ryukyu Islands is the second representative of the genus Terenochiton Iredale, 1914 which was recently reinstated for Leptochiton norfolcensis (Hedley et Hull, 1912), and is characterized by having rudiments of the insertion plates in all valves. T. nomurai closely resembles the type species, but differs in the arrangement of the aesthete pores on the granules of the tegmentum, and less developed rudiments of the insertion plates. Key words: chitons, Leptochiton, Terenochiton, new species, the Philippines, Japan, Papua New Guinea. Описаны два новых вида семейства Leptochitonidae, Leptochiton pumilus sp. nov. и Terenochiton nomurai sp. nov. из тропических и субтропических мелководий западной Пацифики. L. pumilus c Филиппин и Папуа – Новой Гвинеи имеет сетчатовидную скульптуру на раковине, что является довольно редким признаком в этом роде. В этом роде только три вида известны до настоящего времени в тропических мелководьях, в противоположность более чем 130 другим современным видам, которые живут в глубоких холодных водах и в высоких широтах. T. nomurai из островов Рюкю является вторым представителем рода Terenochiton Iredale, 1914, который был недавно восстановлен для Leptochiton norfolcensis (Hedley et Hull, 1912) и характеризуется наличием рудиментов инсерционных пластинок на всех щитках. T. nomurai сходен с типовым видом рода, но отличается расположением пор эстетов на зернах тегментума и менее развитыми рудиментами инсерционных пластинок. Ключевые слова: хитоны, Leptochiton, Terenochiton, новые виды, Филиппины, Япония, Папуа Новая Гвинея.

Two new species of pinnotherid crabs of the genus Indopinnixa Manning & Morton, 1987, are described from Kume andOkinawa islands, Ryukyu Islands, Japan. The new species are distinguished from congeners as well as allied Pinnixa species by a combination of characters of the carapace, male abdominal somites, ambulatory legs, and/or male first gonopod.

Antennular Peduncle

Two new species of Pagurixus Melin, 1939, P. pulcher and P. longipes, are described from the submarine caves of the Ryukyu Islands, southwestern Japan. These species belong to the different informal species group of the genus characterized by the presence or absence of two distinct, longitudinal rows or series of setae on the ventral surface of the antennular ultimate segment. Pagurixus pulcher is most closely allied to P. nomurai Komai & Asakura, 1995, but is differentiated by the more slender ocular peduncles, setation on the ultimate segment of the antennular peduncle, and shape of the anterior lobe of the sixth thoracic sternite. The extremely long and slender carpus of the left cheliped and dactyli of the ambulatory pereopods clearly distinguish P. longipes from other species belonging to the species group characterized by the absence of longitudinal rows or series of setae on the ventral surface of the antennular ultimate segment.
