A new species of Halectinosoma (Copepoda,Harpacticoida) from the Isle of Man

Summary

A new species of Halectinosoma Lang, 1948, H. pterinum sp. nov. is described from the Isle of Man. Examination of this and some other species of the genus under high magnifications suggests that the diagnosis of the genus may have to be modified.     

Revised keys to Paramphiascopsis Lang (Copepoda,Harpacticoida, Diosaccidae) including a new species from deep water off New Zealand

Paramphiascopsis waihonu sp. nov. is described and illustrated from deep water (1116m) off New Zealand. Individuals were retrieved from inside a spent skate (Rajiformes) embryo case in association with the mollusc Choristella sp. The species differs from all others in the genus in segments 3 and 4 of the antennule bearing aesthetascs and inter alia the ornamentation of the abdomen; the P1 basis and general morphology of the male P2 assists in isolating the species. Substantial variability is noted, and revised keys to both sexes of the genus are presented. Brief comments are made on the ecology of the species.     

A remarkable new genus and species of Cynipoidea (Hymenoptera) from Papua New Guinea

During the course of a recent investigation into the phylogeny of the Cynipoidea (Fergusson, 1990) a new species was discovered which is unusually elongate and has a remarkably deep incision between the metanotum and propodeum. This species constitutes a new genus, Eileenella, which is described below.     

Two new species of Limnoriidae (Isopoda) from Papua New Guinea

Limnoria kautensis and Paralimnoria asterosa are two limnoriids new to science. They were found at a depth of 8–9 m in marine conditions burrowing in rainforest logs of timber species sufficiently dense to sink when lost during log-transporting operations. L. kautensis most closely resembles. L. pfefferi, from which it can be distinguished by the absence of a Y-shaped carina on pleonite 5, the bilobed nature of the lacinia mobilis of the mandible and differences in the proportions of the maxilliped, flagellum of antenna 2 and uropods. Paralimnoria asterosa differs from the only other member of its genus, P. andrewsi, in having a pronounced ring of basally-sheated radiating setae on pleonites 4 and 5 plus the pleotelson, and in details of the pattern of carinae, tubercles and depressions on the pleon and pleotelson.     

A new genus of Cletodidae (Copepoda; Harpacticoida) from the Bohai Sea,China

Neoacrenhydrosoma zhangi gen. et sp. nov. is described from specimens recovered from muddy sediments in the shallow waters of the Bohai Sea. On the basis of the structure of the mouthparts, P5 of both sexes and the female genital field, it is suggested that the taxon is related to the Acrenhydrosoma-complex within the Cletodidae. It differs from other known genera in the structure of the exopod in P2–P4 which is two-segmented as a result of the failure to separate the proximal two segments of a three-segmented ramus; and the P5 in as much as the mucroniform process incorporates the exopod, as well as the endopodal lobe of the baseoendopod.     

Three new species of the genus Normanella Brady (Copepoda: Harpacticoida) from the Gulf of Mexico

Three new species of Normanellidae are described from the Texas coast, Gulf of Mexico. Normanella texana sp. nov. has limited areolated patterns on the cephalothorax, short P5 exopod and endopod, short caudal ramus and short caudal seta VI-V. Normanella brevispina sp. nov. is characterized by its relatively long caudal rami, and areolated rostrum. Normanella chanhoi sp. nov. has well-developed areolated patterns on the cephalothorax, six-segmented antennule and a smooth apical margin of the rostrum. N. texana belongs to the bolini -lineage, and N. brevispina to the minuta -lineage. Normanella chanhoi establishes a new lineage of its own.     

On four new species of Cletocamptus Shmankevich, 1875 (Copepoda: Harpacticoida) from inland waters of Argentina

Argentinean specimens of Cletocamptus of the collection of the Smithsonian Institution as well as recently collected material were analyzed and four new species are described. Cletocamptus assimilis sp. nov. and C. tertius sp. nov. seem to be related to C. levis. Cletocamptus pilosus sp. nov. seems to be related to C. stimpsoni. Cletocamptus spinulosus sp. nov. shares the armature formula of the mandibular palp, the armature formula of P1–P4 and the lower insertion level of the innermost seta of the male P5BENP with C. levis, C. assimilis sp. nov. and C. tertius sp. nov. Cletocamptus spinulosus sp. nov. shares the slender seta of the maxillulary arthrite with C. pilosus sp. nov. and C. stimpsoni, and is unique in the strong spinules along the posterior margin of the P2- to P4-bearing somites. Additional comments on some other species and an identification key to the species of Cletocamptus are presented.     

Two new bathyal species of Pseudotachidius (Copepoda: Harpacticoida) from the Beaufort Sea (Alaska,U.S.A.)

Summary

Two new species of harpacticoid copepods are described from the northeastern coast of Alaska, U.S.A. Pseudotachidius brevisetosus sp. nov. and Pseudotachidius bipartitus sp. nov. co-occurred at depths from 659–1144 m. Pseudotachidius brevisetosus is unique in the armature of the ♀ P₅ and the ♂ P₂ endopod. Pseudotachidius bipartitus, with a 2-segmented P₁ endoped is also unique. The setal arrangements of Pseudotachidius coronatus T. Scott and Pseudotachidius similis T. Scott are discussed. The correct setal formulae for all species and a key to the genus are given.     

Some corallanid isopods associated with wood from Papua New Guinea,including three new species (Isopoda: Corallanidae)

Summary

The corallanid isopods, C. nodosa, C. estuaria sp. nov. C. bidentata sp. nov. and C. tridentata sp. nov. have been found within timbers of mangroves and man-made structures in marine and brackish waters around Papua New Guinea. Corallana estuaria, C. bidentata and C. tridentata are new to science and are described in detail. In addition, aspects of the ecology of all four species are considered, including their association with the marine-boring isopods, Sphaeroma terebrans and S. triste.     

A new genus and three new species of parasitoid wasp from Papua New Guinea and redescription of Trigonophatnus Cameron (Hymenoptera,Braconidae, Rogadinae)

ABSTRACT

Two new pill millipede species, namely Hyleoglomeris hoanglien sp. nov. and H. fanxipan sp. nov., are described from high elevations (approximately 2,800–2,900 m) of the Hoang Lien National Park, northern Vietnam. A new species, H. hoanglien sp. nov. is clearly distinguished by the telopods being short, stout and incrassate, femora strongly condensed, tibia without modifications, syncoxital lobe bifid trapeziform, and syncoxital horns with an apical seta and a spine. Hyleoglomeris fanxipan sp. nov., is diagnosed by the telopods being long and robust, tibia without modifications, syncoxital lobe roundly trapeziform, and syncoxital horns truncated at tip. COI-based DNA barcodes of the two species are also provided for the first time in the genus Hyleoglomeris. The K2P genetic distance between the two new species is 0.148. In addition, an identification key to the Vietnamese Hyleoglomeris species is also provided.

Helminths of 26 species of microhylid frogs (Anura: Microhylidae) from Papua New Guinea

Five hundred and sixty microhylid frogs representing 26 species collected from 2002 to 2005 in Papua New Guinea were examined for helminths. Found were three species of Digenea, two species of Cestoda, nineteen species of Nematoda, and two species of Acanthocephala. One hundred and eleven new host records were recorded. Nematodes comprised 73% (19/26) of the species present and 95% (10,581/11,107) of the individuals present. Seventeen of the 26 (65%) helminth species found are currently known only from Papua New Guinea.     

Helminths of ten species of Litoria frogs (Anura: Hylidae) from Papua New Guinea

One hundred and ninety-one frogs collected in Papua New Guinea from 10 species of the genus Litoria, namely, L. angiana, L. arfakiana, L. caerulea, L. congenita, L. eurynastes, L. gasconi, L. infrafrenata, L. iris, L. kumae and L. modica, were examined for helminths. Eighteen species of helminths were found: one species of Monogenea, Parapolystoma bulliense; three species of Digenea, Diplodiscus amphichrus, Halipegus zweifeli and Mesocoelium monas; 13 species of Nematoda, gravid specimens of Aplectana macintoshii, Cosmocerca novaeguineae, Falcaustra papuensis, Maxvachonia adamsoni, Maxvachonia flindersi, Maxvachonia ingens, Meteterakis crombiei, Moaciria moraveci, Parathelandros mastigurus, Physalopteroides milnensis, Pseudorictularia dipsarilis, Seuratascaris numidica, and larvae (in cysts) of Abbreviata sp. and, one species of Acanthocephala, Pseudoacanthocephalus bufonis. Mean number of helminth species per host species was 3.0 ± 1.4 SD (range 1–5), mean number of helminth species per infected frog was 1.1 ± 0.4 SD (range 1–2), and mean number of helminths per infected host was 33.3 ± 5.8 SD (range 1–36). Twenty-eight new host records and two new locality records are reported. The biogeography of the recovered helminths is discussed.     

Two new genera of Laophontidae (Copepoda: Harpacticoida) from the high Antarctic Weddell Sea

Two new genera of the harpacticoid family Laophontidae from the high Antarctic Weddell Sea are described. At present, both taxa cannot be assigned to any of the known genera or lineages of the family. The Antarctic shows the greatest degree of endemism worldwide in several already investigated taxa and, considering the available records, the Laophontidae appear to be no exception to this rule. The available data on the Laophontidae of the Weddell Sea seem to support a hypothesis of an ‘old’ antarctic fauna rather than a recolonization by ‘phylogenetic younger’ taxa after the major climatic changes, which took place in the Antarctic continent and the surrounding waters from the Miocene onwards.     

Gastrointestinal helminths from fifteen species of Litoria and Nyctimystes (Anura: Hylidae) from Papua New Guinea

Three hundred and ninety‐nine individuals representing 10 species of Litoria and five species of Nyctimystes (Hylidae), L. arfakiana, L. bibonius, L. eucnemis, L. genimaculata, L. impura, L. infrafrenata, L. modica, L. nasuta, L. thesaurensis, L. wollastoni, N. gularis, N. kubori, N. papua, N. pulcher and N. semipalmatus collected in Papua New Guinea were examined for helminths. Gravid individuals representing one species of Monogenea (Parapolystoma bulliense), one species of Digenea (Mesocoelium monas), 18 species of Nematoda (Aplectana krausi, Aplectana macintoshi, Aplectana zweifeli, Cosmocerca novaeguineae, Falcaustra papuensis, Icosiella papuensis, Maxvachonia adamsoni, Maxvachonia ewersi, Meteterakis crombiei, Moaciria moraveci, Ochoterenella papuensis, Oswaldocruzia bakeri, Parapharyngdon maplestoni, Parathelandros allisoni, Parathelandros andersoni, Physalopteroides milnensis, Rhabdias australiensis, Seuratascaris numidica) and one species of Acanthocephala (Acanthocephalus bufonis) were found. Also included were immature forms representing one species of Cestoda (as a metacestode), three species of Nematoda (Abbreviata sp., Rictulariidae gen. sp., Ascarididae gen. sp. in cysts), one species of Acanthocephala (unidentified cystacanth), and one species of Pentastomida [Raillietiella sp. (nymph)]. The mean helminth species richness for infected hosts was 1.3±0.6 SD (range one to three species). Sixty‐seven new host records and two new locality records are reported.     

Redefinition of the parastenocaridid genus Proserpinicaris (Copepoda: Harpacticoida), with description of three new species from Korea

Proserpinicaris young sp. nov., Proserpinicaris wangpi sp. nov. and Proserpinicaris imjin sp. nov. are described from subterranean waters of South Korea. They are short-range endemics, allopatric in distribution and closely related to each other, and to two other Far Eastern congeners.

A new genus and five new species of Phoxocephalidae (Crustacea: Amphipoda) from the south-east Brazilian deep sea

Rearing data from higher plants, carrion and bird and mammal nests and burrows are provided for eight species of Heleomyzidae (Diptera): Heleomyzinae: Heleomyza borealis Boheman, Scoliocentra brachypterna (Loew) and Eccoptomera microps (Meigen); Heteromyzinae: Tephrochlamys flavipes (Zetterstedt), Tephrochlamys tarsalis (Zetterstedt) and Heteromyza rotundicornis (Zetterstedt); and Suillinae: Suillia ustulata (Meigen) and Suillia variegata (Loew). The puparia of these species are described. Unique characters and characters in combination distinguish each species and their subfamilies, suggesting that early stages are a valuable source of taxonomic data. Head skeleton and other features suggest contrasting food gathering mechanisms, with heleomyzines suited to feeding on food of low viscosity, suillines on high-viscosity or firm food and heteromyzines on food of intermediate viscosity.
