Review of the genusBembras Cuvier, 1829 (Scorpaeniformes: Bembridae) with description of three new species collected from Australia and Indonesia

The bembrid genusBembras Cuvier is reviewed. Five species,B. japonica Cuvier,B. adenensis Imamura & Knapp and three undescribed species, were assigned to the genus. Type species of the genus,Bembras japonica is redescribed on the basis of 36 specimens including the holotype, and three new species,B. macrolepis, B. longipinnis andB. megacephala, previously misidentified asB. japonicus, are also described on the basis of specimens collected from Australia and Indonesia.Bembras macrolepis differs from its congeners by having large body scales, a long pectoral fin with 17–19 rays and a dark blotch on slightly upper portion to middle of margin, 14–15 anal-fin rays, small head and orbit, and caudal fin with a broad vertical dark band near posterior margin.Bembras longipinnis is distinguished from other members of the genus by having a slightly long pectoral fin with 17–19 rays and lacking a small black blotch near tip of upper rays, caudal fin with a large dark spot most intense in lower lobe, 1–2 gill rakers on upper gill arch, 13–14 anal-fin rays, slightly elong ated head and small orbit.Bembras megacephala is characterized by the following combination of characters: caudal fin with several irregular narrow vertical dark bands, small orbit, pectoral fin with 19–20 rays and lacking a small black blotch near tip of upper rays, head elongate, 2–4 gill rakers on upper gill arch, 15 anal-fin rays and small body scales. A key separating the five species ofBembras is given.     

Two new species of the genusAmblyeleotris (Pisces: Gobiidae) from the Ryukyu Islands,Japan

Two new shrimp-associated gobies,Amblyeleotris yanoi sp. nov. andA. masuii sp. nov. are described on the basis of specimens from Iriomote-jima Island and Okinawa-jima Islands, Okinawa Prefecture, Japan.A. yanoi is distinguished from other members of the genus by the combination of the following characters: 14 anal fin soft rays, 19 pectoral fin rays, 97–103 longitudinal scales, a candle flame-shaped marking on the caudal fin, a very low membrane connecting the pelvic fins and absence of a ventral frenum.A. masuii differs from all other congeners by having 92–97 longitudinal scales, the length of the interpelvic connecting membrane relative to the longest pelvic fin ray (0.43–0.66), black blotches on the sides of the chin, and blue spots on the opercle and preopercle.

The subterranean genus Niphargus (Crustacea, Amphipoda) in the Middle East: A faunistic overview with descriptions of two new species

The Middle East is at the southeastern borderline of the range of the subterranean amphipod Niphargus. The review of new and published data identified two new species and set the guidelines for the future research in the area. The genus in this part of the world seems to be insufficiently studied. The taxonomic status of Niphargus valachicus, population identified as N. spoeckeri and some populations, identified as N. nadarini, need to be reviewed. According to present data, we expect the highest diversity in Western Turkey. The eventual new records of the genus in the Middle East can be expected from those areas where even the longest periods of drought in the recent geological history did not affect the water supply.     

Review of the genusLimnichthys (Perciformes: Creediidae) from Japan, with description of a new species

A taxonomic review of Japanese species of the creediid genusLimnichthys recognised the following:L. fasciatus, L. nitidus (a senior synonym ofL. donaldsoni) andL. orientalis sp. nov.L. fasciatus has an antitropical distribution.L. orientalis sp. nov. differs from its most similar congener,L. nitidus, in having fewer scales above and below the lateral line (2 vs. 3) and the fifth pelvic fin ray shorter or absent, and in the shape of cirri on the lower jaw.     

The leopardChimaera, a new species of chimaeroid fish from New Zealand (Holocephali, Chimaeriformes, Chimaeridae)

A new species ofChimaera is described from three specimens collected from deep water fishing grounds off the North Island of New Zealand at depths ranging from 327–1020 m. This species is distinguished from all other members of the genus by gray coloration with chocolate brown reticulations and spots covering the body and fins, as well as additional external features such as rounded pelvic fins, first dorsal fin with distinct white margin, preopercular and oral lateral line canals sharing a common branch, and morphology of pelvic claspers in males bifid, the distal 1/3 divided, with pale colored fleshy, distal lobes. Comparisons are made toC. monstrosa andC. owstoni, the two most similar species in the genus. this represents the first species ofChimaera to be described from New Zealand.     

Revision of the genus <Emphasis Type="Italic">Nuchequula</Emphasis> with descriptions of three new species (Perciformes: Leiognathidae)

The leiognathid genus Nuchequula can be defined by the following combination of characters: mouth protruding downward; a narrow band of small, slender, villiform teeth in both jaws; teeth on upper jaw strongly recurved; the lateral line almost complete; a dark blotch on the nape. Although the genus was first established as a subgenus of Eubleekeria, it is here raised to generic level on the basis of the aforementioned morphological characters and recent molecular biological evidence. The genus comprises six valid species: N. blochii (Valenciennes 1835), distributed in India and Thailand; N. flavaxilla sp. nov., occurring only at Panay I., Philippines; N. gerreoides (Bleeker 1851), widely distributed in the Indo-West Pacific, from the Persian Gulf to Cape York, Australia, and north to Taiwan; N. glenysae sp. nov., from northern Australia and Ambon, Indonesia; N. longicornis sp. nov., from the Gulf of Thailand and Indonesia; and N. nuchalis (Temminck and Schlegel 1845), occurring in southern China including Taiwan, and southern Japan. Diagnostic characters of the species belonging to the genus are as follows: N. blochii—breast scaled, cheek naked, and a conspicuous black blotch distally on spinous dorsal fin; N. flavaxilla sp. nov.—breast naked, dorsolateral body surface fully scaled, preorbital spine bicuspid and not expanded distally, and second dorsal and anal fin spines conspicuously elongated; N. gerreoides—breast naked, anterior part of dorsolateral surface of body almost completely scaled, and second dorsal and anal fin spines not conspicuously elongated; N. glenysae sp. nov.—breast completely scaled, cheek scaled, and unique complicated sensory canals present on the suborbital area, extending to the nape; N. longicornis sp. nov.—breast naked, dorsolateral body surface fully scaled, preorbital spine bicuspid or tricuspid and extended distally, and second dorsal fin spines only conspicuously elongated; N. nuchalis—breast naked, anterior part of dorsolateral surface of body widely naked, and a conspicuous dark blotch distally on spinous dorsal fin.     

A new species of deepwater flathead,Bembras adenensis (Scorpaeniformes: Bembridae) from the western Indian Ocean

A new bembrid,Bembras adenensis, is described on the basis of specimens collected from the Gulf of Aden, western Indian Ocean. This species is easily distinguished fromB. japonica, the only known congener of the genus, by the following combination of characters: larger orbital diameter, longer head length, pectoral-fin with a small black blotch near tip of upper rays, 3 gill rakers on upper gill arch, 19 pectoral-fin rays, and 15 anal-fin rays (vs. smaller orbital diameter, shorter head length, pectoral-fin with several small spots forming irregular bands, 2 gill rakers on upper gill arch, usually 17 pectoral-fin rays, and 14 anal-fin rays inB. japonica).     

A new Spionidae (Polychaeta) from North Carolina, and a redescription of Marenzelleria wireni Augener, 1913, from Spitsbergen, with a key for all species of Marenzelleria

Marenzelleria bastropi, a new species of Spionidae (Polychaeta) from the brackish water Currituck Sound, North Carolina, is described. The new species is characterized by the great number of chaetigers between the first neuro- and notopodial hooded hooks, the extension of the nuchal organ up to the end of chaetiger 2/middle of chaetiger 3 and the presence of about 60–90 branchiate chaetigers. Marenzelleria bastropi sp. nov. is closely related to M. neglecta (Sikorski and Bick, 2004) and Marenzelleria viridis (Verrill, 1873). Marenzelleria wireni Augener, 1913 is described here for the first time from western Spitsbergen. Adult specimens are investigated and compared with specimens from other areas of distribution.

Epistemma neuerburgii (Apocynaceae, Periplocoideae): A new epiphytic species from Nyungwe National Park, Rwanda, Africa

A new species, Epistemma neuerburgii is described. This species was discovered in the Nyungwe National Park, Rwanda, Tropical Africa during a field investigation of epiphytes in montane rainforest. It was, however, also found in Uganda, in similar environment. E. neuerburgii is the fourth species described for Epistemma, but the other three species are found about 2000 km to the west in Cameroon, Gabon, Ghana, Ivory Coast and Nigeria. E. neuerburgii is an epiphytic climber distinguished by fairly large lanceolate leaves and conspicuous reddish-purple flowers with corolline white, densely hairy corona lobes.     

<Emphasis Type="Italic">Cabillus atripelvicus</Emphasis>, a new species of gobiid fish from the Ogasawara Islands,with a key to species of the genus

Cabillus atripelvicus is described from three specimens, 26.1–40.6 mm in standard length, collected from depth 17–29 m in the Ogasawara Islands. In addition, two small specimens taken by dredge in 50–55 m from Sagami Bay, Honshu, and one from Tachibana Bay, Kyushu, are identified as this species but not designated as paratypes. Cabillus atripelvicus is distinguished from the four other described species of the genus by its high count of 18–20 pectoral rays, presence of median predorsal scales, longer pectoral fins, and distinctive color pattern, including black pelvic fins. The range of C. lacertops Smith, 1959 is extended east to the Marshall Islands and that of C. tongarevae (Fowler, 1927) east to American Samoa. More species remain to be described in the genus.

A new species of deepwater snake-eel,ophichthus aphotistos, with comments onneenchelys retropinna (anguilliformes: Ophichthidae) from taiwan

Ophichthus aphotistos, a new species of snake-eel, subfamily Ophichthinae, is described from three specimens trapped in deep water (700–800 m) off southwestern Taiwan. It is most similar toO. cruentifer but differes from it and other elongate, deep water species ofOphichthus in its vertebral number (158–162), posterior dorsal-fin origin, biserial dentition, and dark coloration. A poorly known species,Neenchelys retropinna Smith &; Böhlke, is reported from the South China Sea for the first time.     

A new species of the genusDiaphanosoma Fischer, 1850 (Crustacea: Daphniiformes: Sididae) from Central Asia and China

Diaphanosoma macrophthalma sp.nov. is described based on material (parthenogenetic females and males) obtained from a number of water bodies of Uzbekistan, Kazakhstan and China. Intra- and interpopulation morphological variability, size range, sex structure and geographical distribution are analyzed.     

Fossil bagrid catfishes from Japan and their zoogeography, with description of a new species,Pseudobagrus ikiensis

Morphological characteristics of fossil bagrid catfishes from six Miocene to Pleistocene localities in Japan are described. A new species of the Middle Miocene bagrid,Pseudobagrus ikiensis, is described, based on five nearly complete specimens (ca. 19 cm SL) and one half-body specimen from the Chojabaru Formation (15 Ma) of the Iki Group in Nagasaki Prefecture. The species is diagnosed by a unique combination of characters: 14–16 anal fin rays, 44–47 vertebrae, deeply forked caudal fin, pectoral spines with serrations on the anterior edge and supraoccipital process extending to the first pterygiophore of the dorsal fin.Pseudobagrus ikiensis is morphologically close to the extantP. fulvidraco, which is widely distributed in China, Siberia and the Korean Peninsula, suggesting that both lineages had appeared by the Middle Miocene. All other fossil specimens are from the Pliocene (3–4 Ma) Ueno Formation (lowest Kobiwako Group, Ohyamada, Mie Pref.) and Tokai Group (Tsu, Mie Pref.), and Pleistocene cave deposits (Inasa, Shizuoka Pref., Mine, Yamaguchi Pref. and Kanogawa, Ehime Pref.). These are incomplete, comprising mainly dorsal and pectoral spines. Being indistinguishable from the extantP. nudiceps, they are thus considered to be included in that lineage. Although the geological distribution of these Plio-Pleistocene fossils nearly overlaps that of the extantP. nudiceps (west of the Suzuka Mountains), fossil specimens have also been found in the Ise Bay area (Tsu), whereP. ichikawai is the only extant bagrid, and further east (Inasa). Based on evidence that the latter is not a sister species ofP. nudiceps, the distribution of the fossils indicates that the range ofP. nudiceps was restricted to west of the Suzuka Mts. during the Pleistocene or Holocene.     

Thysanophrys papillaris, a new species of flathead from the Andaman Sea and Northern Australia (Scorpaeniformes: Platycephalidae)

A new platycephalid,Thysanophrys papillaris, is described on the basis of six specimens (78–121 mm SL) collected from the Andaman Sea and off northern Australia (Timor and Arafura Seas). This new species can be distinguished from other congeners by the following combination of characters: presence of a single short papilla on upper surface of eye, longer snout, smaller body scales. 11 second dorsal-fin rays and 12 anal-fin rays, presence of four or more suborbital spines usually, branched short iris lappet, ctenoid lateral-line scales and interopercle not extended posteroventrally.     

Citharoides orbitalis, a new sinistral citharid flounder from western australia (pleuronectoidei, pleuronectiformes)

A new citharid flounder,Citharoides orbitalis, is described based on four specimens from Western Australia. The new species can be distinguished from the only known congener,C. macrolepidotus, by its longer orbit, greater distance between the upper eye and dorsal profile, and wider space between each eye and the anterior rim of the orbit.
