A new genus and species, Parafoxiphalus longicarpus, and a new species, Metharpinia protuberantis belonging to the family Phoxocephalidae, are described from the Argentine Sea. Both taxa were collected from sandy substrata in the intertidal and subtidal regions. Parafoxiphalus longicarpus is related to Foxiphalus Barnard, 1979 and they share many characters, most of them in plesiomorphic condition. Metharpinia protuberantis is an intermediate species between Metharpinia Schellenberg, 1931 and Microphoxus Barnard, 1960, and its assignation to the first genus is discussed.  相似文献

This paper describes two new species, each consisting of two subspecies, of protandric, octothecal pheretimoid earthworms from Taiwan. They are Metaphire paiwanna sp. nov. typica, Metaphire paiwanna var. liliumfordiI subsp. nov., Metaphire bununa sp. nov. typica and Metaphire bununa var. glareosus subsp. nov. The var. typica of both new species occurred on the west side of the Central Mountain Range, whereas the subspecies, liliumfordi and glareosus, occurred on the east side of the range. Apparently, the Central Mountain Range constitutes a geographical barrier for isolation and subspeciation. Metaphire paiwanna has a male disc medial to male pore (opening of copulatory pouch) with a horizontal ridge, the character shared by holandric and sexthecal Amynthas swanus (Tsai) of Taiwan and Metaphire aggera (Kobayashi) of Korea and Manchuria, whereas M. bununa resembles more closely holandric, octothecal Metaphire riukiuensis (Ohfuchi) of the Riukiu Islands than protandric, octothecal Metaphire stephensoni (Michaelsen) of Indochina.  相似文献

Acanthoplacatus gen. nov., a new genus of viviparous gyrodactylid, is described from the fins and skin of siganid fishes from the Great Barrier Reef, Australia. The genus is characterized by a muscular, tube-like haptor with 16 marginal hooks on the posterior margin. The ventral lobe of the haptor is located anteriorly relative to the dorsal lobe and contains a pair of hamuli and a ventral bar with posteriorly-projecting ventral bar membrane. A dorsal bar is absent. Five pairs of posterior gland cells surround the posterior terminations of the gut. The male copulatory organ is a muscular, non-eversible bulb with several spines around the distal opening. Species of Acanthoplacatus have a bilateral excretory system consisting of six pairs of flame cells and a pair of excretory bladders. Seven new species are described: Acanthoplacatus adlardi sp. nov. and A. amplihamus sp. nov. from Siganus punctatus (Forster, 1801), A. brauni sp. nov. from S. corallinus (Valenciennes, 1835), A. parvihamus sp. nov. from S. vulpinus (Schlegel and Mueller, 1845), A. puelli sp. nov. from S. puellus Schlegel, 1852, A. shieldsi sp. nov. from S. lineatus (Valenciennes, 1835) and A. sigani sp. nov. from S. fuscescens (Houttuyn, 1782). Species can be discriminated by shape and size of the hamuli, marginal hooks and ventral bar and by male copulatory organ sclerite morphology. Three species (A. brauni sp. nov., A. shieldsi sp. nov. and A. sigani sp. nov.) were assessed for seasonal variation of sclerite size. Ten of thirteen morphological characters showed seasonal variation in size for at least one of the species. The characters were longer in winter except dorsal root tissue cap width. Only one character, marginal hook length, showed significant seasonal variation for all three species. Species of Acanthoplacatus were observed to attach using only the marginal hooks and the role of hamuli in attachment is unclear. The dorsal fin of the host is the preferred site for most species but the anal fin, caudal fin and body surfaces are preferred by some species. Prevalences for species range from 57 to 100%.  相似文献

Two new genera of the bryozoan family Calloporidae are described from New Zealand. The first, Leptinatella, is introduced for L. gordoni n. sp., specimens of which have been referred in the past to Watersia militaris (Waters) but are distinct from this species, which is a phase of the cribrimorph Corbulipora tubulifera (Hincks). The second genus, Bryocalyx, is introduced for B. cinnameus n. sp., which has small, conical colonies anchored by rhizoids. Another species of Bryocalyx is known from a few fragments only: and has also been referred in the past to Watersia sp. It is briefly discussed, but left unnamed here.  相似文献

Five species of the hermit crab genus Paguristes Dana, 1851, initially reported by Ortmann (1892) from Japan, are revised based on the materials reported by Ortmann (1892), Doflein (1902), Balss (1913) and Miyake (1978), and on newly collected specimens. The specific status of P. palythophilus Ortmann, 1892, is clarified, and a species confused with P. palythophilus is described as new, P. albimaculatus. It has been revealed that P. kagoshimensis Ortmann, 1892, is actually a junior subjective synonym of P. digitalis Stimpson, 1858. The species heretofore assigned to P. kagoshimensis is described as new, P. versus. It has been confirmed that Paguristes acanthomerus Ortmann, 1892, is a valid species and that P. barbatus sensu Ortmann, 1892, is the same species as P. ortmanni Miyake, 1978. Further, a new species, P. doederleini, is described for P. setosus sensu Ortmann, 1892. It is also shown that a part of the group of specimens identified as Paguristes puniceus by Miyake (1978) is referable to P. doederleini. In addition to the three new species recognized herein, the four previously described species are also redescribed in detail in order to make clear their taxonomic status.  相似文献

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.  相似文献

Enchytraeid surveys were made in China, mainly along the Changjiang (Yangtze) River Basin, during the period 1991–1999. Among the findings, four terrestrial species of Marionina are new to science and well illustrate the taxonomic complexity of the genus as currently defined. Marionina sinica sp. n. is characterized by a specific chaetal distribution, the marionine pattern of the dorsal blood vessel, and elongate, fusiform, spermathecal ectal ducts. Marionina sacculata sp. n. is distinguished by the possession of a pair of pouch-like oesophageal appendages in IV, the lack of lateral chaetae in VII–XI, a marionine pattern of the dorsal blood vessel, and short spermathecal ectal ducts gradually expanding into spherical ampullae. Both M. sinica and M. sacculata have minute bodies (2–3 mm long in vivo) and lack spermathecal accessory glands. The former species shows its closest aYnities with the European M. brendae Rota, 1995, whereas the latter is closest to the German M. hoVbaueri Möller, 1971, for which an amended diagnosis is provided. Marionina seminuda sp. n. has only ventral chaetal bundles, distributed from III onwards and bisetose. It is similar to the Holarctic M. subterranea (Knöllner, 1935) in lacking entirely the lateral chaetae and in having the brain incised posteriorly, the dorsal vessel bifurcating behind the pharynx, and coelomocytes containing opaque granules, but diVers from it in having the longest chaetae in preclitellar segments and gland cells distributed all over the spermathecal ectal ducts. Marionina righiana sp. n. is diagnosed by the location of the head pore on the prostomium, the absence of lateral chaetae from VIII (VII or IX) onwards, the possession of free spermathecae extending backwards through one to four segments, the brain deeply incised posteriorly, the lumbricilline pattern of the dorsal blood vessel, and the opacity of coelomocytes in vivo. Prior to this study, members of the genus so atypical as M. righiana with respect to the position of the head pore and the structure of the spermathecae were known only from South American soils. Until the taxonomy of Marionina has been more thoroughly assessed and revised, the assignment of the four species to this large assemblage should be regarded as tentative.  相似文献

The list of Phoridae recorded from Tasmania is increased from five species in three genera to at least 52 species in eight genera. One species on the original list is transferred to the status of being incertae sedis. One new genus and 37 new species are described, two being reported from mainland Australia also. One species was previously only known from New Zealand, five from mainland Australia, four from Europe but one of which is now an almost cosmopolitan tramp species and one being from the Holarctic Region. However, one of the 'European' species may have orginally been introduced to Europe from Tasmania. Keys to genera, to all known species of Aphiura, to the Tasmanian species of Megaselia and to the Australasian species of Metopina are provided. A newly named and a new mainland Australian species of Aphiura, three mainland Australasian species of Metopina and three from Papua New Guinea are described and seven undescribed males (given code letters only) of this genus are included in the key (four from Papua New Guinea, two from Western Australia and one from Tonga). Aphiura and Paraphiura are transferred to the tribe Metopinini and the tribe Beckerinini is set aside, as it cannot be satisfactorily characterized as it is currently conceived. Megaselia dissita is synonymized with M. comparabilis.  相似文献

Kronborgia isopodicola sp. n. (Turbellaria: Neorhabdocoela: Fecampiidae) is described from the South Island of New Zealand. The species has a parasitic phase within the haemocoel of the intertidal isopod Exosphaeroma obtusum (Dana). Sexes are separate: each female worm, emerging when mature from its host, secretes a cocoon around itself in which it is joined by a male. Cocoons are found under rocks, are approximately 10 mm long and reflect the shape of the contained female. The worms spawn and lay numerous egg capsules, each containing two embryos. Although placed in Kronborgia Christensen and Kanneworff, 1964 because it is dioecious, K. isopodicola exhibits some characters typical of the genus Fecampia Giard, 1886. It differs from all other described fecampiids by its possession of eyes throughout life.  相似文献

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.  相似文献

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.  相似文献

In an attempt to better document the invertebrate biodiversity of the threatened fauna of Papua New Guinea (PNG), 208 microhylid frogs representing 13 species collected in 2009 and 2010 in PNG were examined for endoparasitic helminths. This study found mature individuals of one species of Digenea (Opisthioglyphe cophixali), adults of two species of Cestoda (Nematotaenia hylae, Cylindrotaenia sp.) and cysticerci of an unidentified cestode species; adults of nine species of Nematoda (Aplectana krausi, Bakeria bakeri, Cosmocerca novaeguineae, Cosmocercella phrynomantisi, Falcaustra papuensis, Icosiella papuensis, Ochtoterenella papuensis, Parathelandros allisoni, Parathelandros andersoni), and one species of Acanthocephala (cystacanths in the family Centrorhynchidae). There was a high degree of endemism among the helminth species infecting the microhylids, with 83% of the species known only from PNG. Yet the helminth fauna infecting Papuan microhylids are generalists with direct life cycles (no intermediate host) that also infect other anuran species. We thus conclude infection is more dependent upon habitat conditions than diet. Twenty-nine new host records are reported.  相似文献

Three new species of oribatid mites belonging to the genus Liebstadia are described from Mongolia. The new species are characterized by the poorly developed pteromorphae; the club-shaped head of the sensilli; the absence of the dorsosejugal suture; the dorso-ventral thickness, and the length and arrangement of notogastral setae. In addition, L. similis (Michael, 1888) is redescribed and recorded for the first time in Mongolia. Protoribates serratomarginatus Mahunka, 1983 is synonymized with L. similis. A key to the known species of the genus Liebstadia is given.  相似文献

The tropical African species of the genus Exoprosopa Macquart placed by Bezzi (1924) in his group 10, E. busiris are reviewed. A key, short diagnoses and outline distributions are provided for each species. E. albonigra Bezzi and E. saskae Szilády are shown to be synonyms of E. luteicosta Bezzi; E. engyoptera Hesse a synonym of E. brevinasis Bezzi; and E. ferrieri Hesse a synonym of E. decastroi Hesse. Two new species are described; E. selenops from Kenya and E. glossops from Nigeria.  相似文献

The Palaearctic species of the genus Ammoplanus Giraud are revised, based on material of over 1750 specimens from Europe, North Africa and Central Asia. For almost all species it was possible to examine the type material and in six species the lectotypes have been designated, in two cases (A. perrisi and A. marathroicus) the neotypes. As a result 38 species are recognized as valid, keyed out and commented on. Eight species are described as new and four species names are here placed in synonymy. Several species are of wide distribution, which made it necessary to include also those described from Central Asia and Mongolia. The keys are made to all Palaearctic species but no material is known from the regions east of Mongolia, although four undescribed species are available from South-East Asia. The Afrotropical species are listed and most of them were also examined. Two subgenera are recognized in the region; 32 species are classified in Ammoplanus sensu stricto and six in the subgenus Ammoplanellus. In the nominal subgenus the following species are described as new: A. atlasensis from Morocco, A. biscopula from Israel, A. biskrensis from Algeria, A. denesi from Turkey (Anatolia), A. freidbergi and A. kaplanae from Israel, A. minutus from Bulgaria and Turkey and A. strumae from Bulgaria and Greece. New synonymy: A. angelae becomes a junior synonym of rhodesianus (known before only from Africa), A. crudelis a synonym of A. kaszabi, A. handlirschi a synonym of A. marathroicus, A. suarezi a synonym of A. kohlii, A. subcompressus of A. gegen, A. orbiculatus of A. simplex and A. zarcoi of A. kohlii; A. wesmaeli is confirmed as a synonym of A. perrisi. Otherwise the synonymy is corrected under A. bischoffi and the names A. dusmeti and A. curvidens are re-established as valid. In a short review of the African species A. (Ammoplanellus) cradockensis Arnold, 1959 is placed as a new synonym under A. (Ammoplanellus) latiscapus Leclercq, 1959. The nomenclatural changes are explained under the relevant species.  相似文献

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.  相似文献
