A new species of the genus Sabellaria Lamarck, 1812, is described from shallow waters off Onjuku, the Pacific side of Boso Peninsula, Chiba, Japan. Sabellaria isumiensis n. sp. is a gregarious species building colonies of tubes made of sand and shell debris over 2 m wide in the intertidal to subtidal zone of the rocky shores. The new species is distinguished by the character combination of having 1 or 2 pairs of nuchal spines, median teeth of outer paleae with 3–5 lateral spines, two kinds (long and short) of opercular paleae in the middle row of the crown, with slender blades of long ones curved outward. Morphological features of the species are described in details and compared to those of congeners from Japan and world-wide. We re-describe three poorly known sabellariid species, Sabellaria javanica Augener, 1934 from Java, Indonesia, S. chandraae de Silva, 1961 from Galle Force, Sri Lanka, and Neosabellaria uschakovi Kirtley, 1994 from the Far Eastern Seas of Russia. The descriptions are based on the type specimens, and we particularly emphasize the head morphology and paleal characters. We provide a summary of diagnostic characters in the genus Sabellaria and propose new morphological groupings that later will be tested in the framework of a formal phylogenetic analysis.

The palaemonid shrimp genus Palaemon Weber 1795 is currently represented by 87 species worldwide, of which 36 species inhabit freshwater environments. In this study, we describe a new species of the genus, P. septemtrionalis, primarily based on material collected from rivers in Miyagi Prefecture, Tohoku District, northeastern Japan. The present new species is morphologically and genetically close to Palaemon paucidens De Haan, 1841, but it is morphologically distinguishable from the latter by the chela of the pereopod 2 being longer than the carpus (versus shorter than the carpus in P. paucidens) and the possession of a low, laminar convexity on the flexor margin of the pereopod 3 dactylus just proximal to the base of the unguis (such a laminar structure is absent in P. paucidens). Comparison of partial sequences of the mitochondrial 16S rRNA gene supports the recognition of the new species. Examination of museum collections and a BLAST search on GenBank revealed that the geographical range of the new species includes the Sea of Japan side ranging from Hokkaido to Hyogo Prefecture and the Pacific side ranging from Aomori to Miyagi Prefecture. An identification key to the 13 Japanese species of the genus is presented.

A New Species

The genus Mongolotettix Rehn, 1928 is a small genus of family Adrididae. It has nine species discovered from the Far Eastern Asian countries, including China, Japan, Korea, Mongolia, and Russia [Bolívar, 1898; Uvarov, 1914; Caudell, 1921; Chogsomzhav, 1974; Li et Lian, 1994; Wan, Ren et Zhang, 1998; Xie et Li, 2000, Kim et Kim 2005; Dong, et al, 2015; Shi et al, 2016; Storozhenko, 2016; Eades et al, 2017; Zhang et al, 2017]. In the present paper, we describe a new species of the genus from Hubei, China. Type specimens are deposited in the College of Plant Protection, Shandong Agricultural University, Taian, Shandong, China.

Alpheid Shrimp

Three new species of the alpheid shrimp genus Salmoneus Holthuis, 1955 are described from shallow waters of Guam (Mariana Islands), Moorea (Society Islands, French Polynesia), and Panglao (Bohol, the Philippines). The description of Salmoneus paulayi n. sp. is based on three specimens collected on reef flats in the vicinity of Guam’s Apra Harbor, Talofofo, and Mangilao. Salmoneus komaii n. sp. is described on the basis of a single specimen collected at Barracuda Rock, one of Guam’s popular diving sites. Finally, Salmoneus poupini n. sp. is described based on eight type specimens from several sites in the Moorea lagoon and one additional specimen from Panglao. The three new species appear to be closely related to each other, sharing several features on the minor and major chelipeds, the most obvious being the presence of widely spaced teeth on the finger cutting edges of the major chela. In addition, S. paulayi n. sp. is characterised by the presence of rounded, finely striated convexities intercalated between the teeth on the fingers of the major chela; these convexities are present, but much less developed in S. komaii n. sp. and S. poupini n. sp. The closest relative of these three new species appears to be S. sketi Fransen, 1991 from the eastern Atlantic, the only other species of the genus with widely spaced teeth (instead of serrations) on the cutting edges of the major chela.

A new species of spider crab, Hemus magalae n. sp. (Majidae), is described from a single male specimen from Islas de las Perlas, Pacific Ocean coast of Panamá. This species differs from its congeners with respect to many features of the carapace including mid-line elevation and lateral dentition. Hemus A. Milne-Edwards, 1875, now includes four species, three from coastal waters of the eastern Pacific Ocean and one from shallow waters in the tropical western Atlantic Ocean. A key to the Pacific and Atlantic species of Hemus is provided.

Five currently known Japanese species of the eutheiine genus Paraneseuthia occur on Honshū, Shikoku, Kyūshū, and Ishigaki-jima of the Ryūkyū Archipelago. The southernmost Japanese species was separated from its geographically (and very likely phylogenetically) closest relatives that live on Kyūshū by over a thousand kilometers of the Pacific Ocean. Paraneseuthia zanetae sp. n., found on Okinawa-jima, the largest Ryukyuan island, is described, filling this wide distributional gap. The new species is yet another member of the informal P. paradoxa group, which comprises all Japanese members of this genus that share similar male protibial modifications and a complicated structure of the aedeagus; also two Russian Far Eastern species show close morphological affinities to those inhabiting the Japanese Archipelago.

Posterior Ring

Maritrema pacifica n. sp. has an incomplete posterior ring of vitellaria, a spiny cirrus, a trilobed ovary, and a well-differentiated metraterm. It differs from M. patulus Coil, 1955 in the larger body, longer esophagus, round rather than slit-like genital pore, and larger eggs. It differs from M. interrupta Oshmarin, 1970, M. eroliae Yamaguti, 1939, and M. kitanensis Shibue, 1953 in the smaller cirrus sac containing sparse prostate cells. M. pacifica has the following definitive hosts: Larus californicus Lawrence, L. occidentalis Audubon, Turdus migratorius L. from Oregon, and Crocethia alba (Pallas) from British Columbia. The metacercariae, from Orchestoidea corniculata from California, became ovigerous in Locke's solution at 39 °C.Maritrema paracadiae n. sp. (synonym M. acadiae of Deblock and Rausch (1972)) differed from the type specimens of M. acadiae (Swales, 1933) in the proportionately larger oral and ventral suckers; the larger, inverted J-shaped cirrus sac containing prominent prostate cells; and the distribution of the uterus within, instead of overlapping, the posterior vitellarian ring. M. paracadiae was found in the intestine of Bucephala islandica (Gmelin) from Washington.

A New Species

A new species of caprellid, Deutella mazatlanensis n. sp., is described from Mazatlán Bay, (east Pacific México). Deutella mazatlanensis was found associated with bryozoans, hydroids and sponges in shallow waters. The new species can be differentiated from the remaining species of the genus mainly by the dorsal, anteriorly directed projection on the head; the two dorsal projections and a lateral acute projection anteroventrally projected on pereonite 2 and gnathopod 2 in males. The presence of this species on the Mexican Pacific coast, constitutes the fourth report of Deutella genus for the Pacific Ocean and the first record from the tropical Eastern Pacific.

An account is given of the names of families, genera, and species of hydroids established by C.M. Fraser of Canada, excluding those from Allan Hancock Pacific Expeditions and the Allan Hancock Caribbean Sea Expedition. The names of four families, 11 genera, and 101 species are attributed to him in this work, complementing those of another two genera and 164 species described by Fraser in various Allan Hancock publications. Information is provided on type localities of his new species, on locations and kinds of type material in existence, where known, and on the current taxonomic status of families, genera, and species described by him in works reviewed herein. Two replacement names (Thuiaria geniculata Fraser, 1918a and Salacia fraseri Calder, 1991) exist for Thuiaria distans Fraser, 1914a (not Thuiaria distans Allman, 1877). The widely overlooked senior synonym, T. geniculata, is recognized as the valid name of the species. Diphasia alta nom. nov. is proposed as a new replacement name for the permanently invalid junior primary homonym Diphasia robusta Fraser, 1943a (not D. attenuata robusta Billard, 1924). In addition, Cryptolaria crassa nom. nov. is proposed as a new replacement name for the junior secondary homonym Cryptolaria rigida (Fraser, 1948) [not C. rigida (Fraser, 1940a)]. Lectotypes have been designated for 47 of the species to establish objective standards for application of their names. Corymorpha adventitia Fraser, 1941b, from the Pacific coast of Panama, is assigned to Ralpharia Watson, 1980, as R. adventitia. No type specimens are known to exist for seven of the species considered, including one holotype (of Hebella eximia Fraser, 1944a) missing from its bottle. Particular attention has been paid to dating and chronology of the 51 publications of Fraser covered in this work. Earlier bibliographic errors are corrected, most notably establishing that the book Distribution and relationship in American hydroids was published in early 1947 rather than 1946 as per the title page.
