Two new species of Asellota (Crustacea,Isopoda) from coral reefs on Iriomote Island,Okinawa, Japan

Pleurocope iriomotensis sp. n. and Prethura tuberculata sp. n. are described from Iriomote Island, Ryukyu Archipelago, southern Japan. These are the first records of Pleurocope from the Pacific and of Prethura from the Asian Pacific coast. Pleurocope iriomotensis differs from its congeners in having lateral spine-like processes on pereonite 4 and coxal plates of pereonite 7. Prethura tuberculata can be distinguished from its single congener in having a lateral short projection of protopod of pleopod 2.     

Coulmannia rossensis sp. n. (Isopoda, Asellota, Paramunnidae) from the Ross Sea, Southern Ocean

A new species of Coulmannia, Coulmannia rossensis, is described from the Ross Sea, Antarctica. It is most similar to Coulmannia ramosae Castelló, 2004, but can easily be distinguished from this species bythe males yielding a pair of granulate humps on the dorsum of the pereonites 1-6 and a single granulate hump on the pereonite 7 and the free pleonite. Coulmannia rossensissp. n. is sexually dimorphic. The dorsal sculpture of the female bodies yield a single granulate hump on all the pereonites and free pleonite. The species of the genus Coulmannia are restricted to the Southern Ocean, and Coulmannia rossensissp. n. is the fourth species included in it.     

A new genus and species of larval mite (Acari: Prostigmata: Microtrombidiidae) parasitising Orthoptera (Tettigoniidae) from the Sierra Nevada, Spain

Nevada capileirarum n. g., n. sp. (Acari: Microtrombidiidae: Microtrombidiinae) is described from ectoparasitic larvae parasitising two endemic species of Orthoptera (Tettigoniidae), Baetica ustulata (Rambur) and Pycnogaster inermis (Rambur) from the Sierra Nevada mountain range, Granada, Spain. A key to the larvae of microtrombidiine genera with three dorsal scuta and a coxal setal formula of 2-1-1 is presented.     

Three new species of Fissarcturus (Isopoda, Antarcturidae) from the Southern Ocean

Fissarcturus bathyweddellensis sp. nov. and Fissarcturus sandwichi sp. nov. are described from the abyssal Southern Ocean near the Antarctic Peninsula and Fissarcturus rossi sp. nov. is described from the shallow Ross Sea. A list of all described species of Fissarcturus is given. The new species differ from recognized species of the genus in the following respects: F. bathyweddellensis can be distinguished based on spination on the dorsum of the body, which is described in detail herein. It is most similar to F. emarginatus Brandt, 1990, but this has, for example, a shorter and less stout second cephalic spine. F. rossi can also be distinguished from F. bathyweddellensis based on spine pattern. Whereas all dorsal spines of F. bathyweddellensis are smooth, those of F. rossi are covered with spinules. F. sandwichi can be distinguished from the other species of the genus by the strong frontally bent supraocular spines (females with second cephalic spines) and dorsal body surface, which is covered with flat, cauliflower-like elevations in submedial, lateral and coxal rows.  © 2007 The Linnean Society of London, Zoological Journal of the Linnean Society , 2007, 149 , 263–290.     

A new species of Jesogammarus from the Iki Island,Japan (Crustacea,Amphipoda, Anisogammaridae)

A new species of anisogammarid amphipod, Jesogammarus (Jesogammarus) ikiensis sp. n., is described from freshwaters in the Iki Island, Nagasaki Prefecture, Japan, based on results of morphological and molecular analyses. The new species is distinguished from all members of the genus by the combination of small number of setae on dorsal margins of pleonites 1–3, short and small number of setae on posterior margins of peduncular articles of antennae, mandibular article 1 without setae, well developed posterior lobes of accessory lobes of coxal gills on gnathopod 2 and pereopods 3–5, and pectinate setae on palmar margin of female gnathopod 2. A key to all the species of Jesogammarus is provided.     

New entodiniomorphid ciliates from the intestine of the wild African white rhinoceros belong to a new family, the Gilchristidae

Gilchristia artemis n.g., n.sp. and Digilchristia draconis n.g., n.sp. in the order Entodiniomorphida are described from the large intestine of the African white rhinoceros, and a new family Gilchristidae is proposed to contain them. These new species have a C-shaped adoral polybrachykinety, a slender vestibular polybrachykinety, and paralabial kineties along the ventral side of the adoral polybrachykinety in their retractable adoral ciliary zone, showing the same arrangement as in the rumen ciliates in the family Ophryoscolecidae. G. artemis has two skeletal plates and D. draconis one plate. In both species the dorsal skeletal plate is bow-shaped, folded in half longitudinally, twisting in the anterior part, and lying along the dorsal left side of the macronucleus. The second plate of G. artemis is slender and lies along the ventral side of the macronucleus. G. artemis has three ciliary arches and D. draconis has four arches along the dorsal and ventral sides of the body. Their arches are long and non-retractable, closely resembling those of ciliates in the families, Spirodiniidae and Cycloposthiidae, and are not analogous to the single retractable ciliary arch of the rumen ciliates in the family Ophryoscolecidae.     

A new genus and species of Renaudarctidae (Heterotardigrada: Arthrotardigrada) from Ryukyu Archipelago,Japan

A new armoured marine tardigrade, Nodarctus hallucis gen. et sp. nov., is described from specimens collected from sandy beaches of Haterumajima, Ishigakijima and Okinawajima Islands, Ryukyu Archipelago, Japan. It is a member of the rare family Renaudarctidae, which is characterized by a stocky body with dorsal and ventral plates and stumpy legs with digits, claws and accessory filaments. However, the collected animals have prominent characters that differ from the two known species of the family: subdivided dorsal segmental plates I–III lacking lateral processes, an acute caudal spike, indented sensory plates, short spikes and peculiar papillae on legs I–III, basal spikes of legs IV and only two digits on legs IV. These differences justify the erection of a new genus and species for the animal. Morphological affinities with other marine taxa, the function of the leg papillae and the distribution pattern of the new species are discussed.http://zoobank.org/urn:lsid:zoobank.org:pub:041878AA-B437-45BF-80E3-32591D21D965     

The morphology of the larval stages of three species (Arrenurus mediorotundatus Thor, 1898; Arrenurus conicus Piers 1894; and Arrenurus cylindratus Piers, 1896) of the Megaluracarus subgenus (Acari: Hydrachnidia: Arrenuridae)

The morphology of the larval stages of three species (Arrenurus mediorotundatus, Arrenurus conicus and Arrenurus cylindratus) belonging to the Megaluracarus subgenus is described. Particular attention is paid to the common characters of the three species in which they differ from the other species belonging to the other subgenera. These are: the shape of the excretory pore plate, the shape of the dorsal plate, the length of coxal plate II medial margin and the C1-CpI, C4-CpIII distances. Other characters differ between the three species also. These are: the shape of the dorsal plate, the shape of coxal plate III, the shape of excretory pore plate and the presence or absence of secondary setae of the IFe3 setae.     

Ryocalanus spinifrons,a new species of Ryocalanidae (Copepoda: Calanoida), from the southwestern part of Sagami Bay,Japan

A new Ryocalanoid copepod, Ryocalanus spinifrons, collected by the MTD net system at a depth of 1400 m from the southwestern part of Sagami Bay, Japan, is described. The new species is morphologically very close to R. infelix Tanaka, 1956 (female unknown) from the Izu region of Sagami Bay. It is distinguished from other species by the presence of 12 long spinules on the ventral inner side of the fifth pedigerous somite, nine setae on the coxal epipodite of the maxillule and nine large robust spinules on the coxal segment of the fourth leg. The row of five robust spines on the paragnath distinguishes R. spinifrons.     

A remarkable new species of Euragallia from Peru (Insecta, Hemiptera, Cicadellidae, Agalliini), including the description of a peculiar structure of the male genitalia

A new species of Euragallia Oman, 1938 from Peru (Pasco Department) is described and illustrated. Euragallia batmanisp. n. can be distinguished from the other species of the genus by the very posteriorly pronounced male pygofer, with an apical hook-like projection, and by the well-developed dorsal area of the aedeagal base, resembling the open wings of a bat. With the addition of Euragallia batmani sp. n., the number of Euragallia species is increased to 21. Only one additional species of the genus is recorded from Peru (Euragallia prion Kramer, 1976). A comparison between the new species and Euragallia prion is provided. A conspicuous structure, which connects the subgenital plates to the styles, is described in detail and named.     

Hyalella montezuma,a new species (crustacea: amphipoda) from montezuma well,Arizona

Two distinct species of Hyalella Smith, with no intermediate forms, occur in the Arizona limnocrene known as Montezuma Well. One is referable to the inermis type of H. azteca (Sauss.). The other is a new and presumably endemic species, H. montezuma, characterized by elongate appendages, mucronation of tergites of pereonite 7 and pleonites 1 & 2, and remarkably enlarged mouthparts; the inner plate of maxilla 1 is broad and armed with up to 30 plumose setae, rather than the 2–3 apical setae that typify the genus. H. azteca occurs alone in a small stream emerging from the Well; both species coexist at the weedy margins of the Well; and H. montezuma swims alone in the open water, where it is a member of the plankton. A high level of free CO₂ in the water serves as a barrier to fish, indirectly allowing Hyalella to colonize the limnetic zone where it represents, perhaps, one of four of the World's freshwater planktonic amphipods. Theoretically, the ancestors of H. montezuma arrived at the Well sometime more than 11,000 years BP, when it was a new steep-walled collapse basin lacking fish; H. azteca appeared later after a shallow littoral zone had developed. The two species are reproductively isolated at present.     

A new genus and species of Philopteridae (Phthiraptera: Ischnocera) from the trumpeters (Aves: Gruiformes: Psophiidae)

A new chewing louse genus and species belonging to the Philopteridae, namely, Palmaellus inexpectatus n. gen., n. sp., is described. The new genus is distinguished from the other ischnoceran genera hitherto described by its peculiar characters of the dorsal anterior head plate with 2 postero-lateral projections, pterothorax and abdomen with scarce chaetotaxy, male genitalia with simple mesomere and paramere lacking inner digitiform projection, and the genital region of female with postero-vulvar plates bearing setae. It is a parasite of the trumpeters, an avian family endemic to South America's Amazon Basin.     

First record of Aulacidae (Hymenoptera: Evanioidea) from New Caledonia with descriptions of three new species of Aulacus Jurine

Abstract The parasitoid wasp family Aulacidae is recorded for the first time from New Caledonia, and three new species are described: Aulacus burwelli, A. coracinus , and A. emineo . Although recorded from just a few specimens, these species appear to be restricted to the moist evergreen rainforest areas of the main island of Grande Terre. They appear unrelated to Australian members of the family, based on a number of characters associated with the forewing venation and hind coxal morphology, as well as size and colour. A key to distinguish the species is presented, as well as information on their distribution and possible relationships.     

Callionymus leucopoecilus,a new dragonet (Callionymidae) from the Yellow Sea

Callionymus leucopoecilus, a new species of dragonet from the Yellow Sea, is described and illustrated. The new species is characterized by 4 spines in the first dorsal fin, 9 rays each in the second dorsal and anal fins, ii, 5, ii principal caudal fin rays, a preopercular spine formula of      

A new species of lentic breeding Korean salamander of the genus Hynobius (Amphibia, Urodela)

A new species of salamander, Hynobius yangi, is described from Kori (=Hyoam-ri), Busan-shi, southeastern Korea. It is a lentic breeder belonging to the H. nebulosus species group, and has long been confused with another Korean species H. leechii. The new species, however, is genetically substantially differentiated from Korean and Japanese relatives. Hynobius yangi is morphologically very similar to H. leechii, but could be differentiated from it by the tail shape, degree of limb separation, shape of vomerine teeth series, shape of egg sac, and dorsal coloration.     

Notes on planthoppers of the tribe Hemisphaeriini (Homoptera, Fulgoroidea, Issidae) from Vietnam with a description of a new genus and a new species

A new genus and a new species of the tribe Hemisphaeriini Melichar of the family Issidae Spinola are described from Northern Vietnam. Lectotype of Hemisphaerius interclusus Noualhier, 1896 is designated. New data on the distribution and ecology of H. interclusus and H. hippocrepis Constant et Pham, 2011 in Southern Vietnam are provided.     

A new copepod (Siphonostomatoida: Lernanthropidae) parasitic on a Red Sea immigrant dragonet (Actinopterygii: Callionymidae), with a review of records of parasitic copepods from dragonets

A new species of parasitic copepod of the family Lernanthropidae is described from an immigrant population of the blotchfin dragonet Callionymus filamentosus Valenciennes (family Callionymidae) in the Eastern Mediterranean. Both sexes are described on the basis of material caught in Egyptian waters off the Alexandria coast at Abuqir. The new species shares with Lernanthropus breviculus Kabata, 1979 the possession of a small dorsal plate on the trunk that is so narrow at its origin that it does not overlap the bases of the fourth legs, which are therefore visible in dorsal view. These species differ in the shape of the cephalothorax and in the extent of the dorsal plate, which is shorter in the new species, revealing the caudal rami in dorsal view. Previous records of parasitic copepods utilising callionymids as hosts are reviewed: most belong to the families Pennellidae and Chondracanthidae.
