A total of 61 species of hydroids, belonging to 13 families and 23 genera, were found during the Spanish Antarctic expedition
Bentart 95 with the RV Hespérides. Ten of the species were identified only to generic level. The dominance of the subclass Leptothecatae, with 57 species,
was remarkable. The remaining four species belong to the subclass Anthoathecatae. By far the most diverse family was the Sertulariidae,
with 25 species (41%), followed by Haleciidae with nine species (15%) and Kirchenpaueriidae with six (10%). The family Plumulariidae,
represented by one species of Nemertesia, is recorded for the first time from Antarctic waters. Eudendrium scotti, Perarella clavata and Symplectoscyphus hero are each recorded for the second time. Symplectoscyphus with 11 species was the dominant genus. Almost 60% of the species diversity is concentrated in just a little more than the
20% of genera. Nearly 70% of the species are endemic to Antarctic waters and 90% of them are restricted to Antarctic or Antarctic/sub-Antarctic
waters. 相似文献

Twenty-two species of benthic hydroids, belonging to ten families and 14 genera, were found in a hydroid collection obtained
in the Balleny Islands during the BioRoss expedition with the NIWA research vessel Tangaroa in 2004. Twenty of those species constitute new records for the Balleny Islands, raising the total number of known species
in the area to 25. Most are members of the subclass Leptothecata, although the subclass Anthoathecata is also relatively well
represented. Kirchenpaueriidae and Sertulariidae constitute families with the greatest numbers of species in the collection,
with five species (20%) each. Oswaldella with five species (20%) and Staurotheca with four (16%), were the most diverse genera. Twelve species (63%) are endemic to Antarctic waters, most of them with a
circum-Antarctic distribution, and 17 (89%) are restricted to Antarctic or Antarctic/sub-Antarctic waters. Although the Balleny
Islands hydroid fauna seems to be a typical Antarctic assemblage, it has some striking peculiarities, namely the absence or
low representation of some typical and widespread Antarctic genera (Antarctoscyphus and Schizotricha/Symplectoscyphus, respectively). 相似文献

Two species of the genus Oswaldella Stechow, 1919 new to science (Oswaldella crassa sp. nov. and O.␣curiosa sp. nov.) were studied. Both species are described and figured; their systematic position amongst the remaining species of
the genus is discussed. The material originates from the Bransfield Strait area (Antarctica) and was collected during the
United States Antarctic Research Program with R.V. Eltanin. A comparative table listing the main features of the known species of Oswaldella is presented. Finally, a general survey of geographical and bathymetrical distribution of the known species of Oswaldella is given.

Twenty-three species of benthic hydroids, belonging to eight families and 13 genera, were found in a hydroid collection from
Peter I Island, collected during both the Bentart 2003 and Bentart 2006 Spanish expeditions with BIO Hespérides in 2003 and 2006. Fourteen out of the 23 species constitute new records for Peter I Island, raising the total number of known
species in the area to 30, as also do seven out of the 13 genera. The majority of the species are members of the subclass
Leptothecata; the subclass Anthoathecata being scarcely represented. Sertulariidae is the family with the greatest number
of species in the collection, with eight species (35%), followed by Lafoeidae with five (22%). Symplectoscyphus with four species (17%) and both Antarctoscyphus and Halecium with three (13%), including H. frigidum sp. nov., were the most diverse genera. Twenty species (ca. 77%) are endemic to Antarctic waters, either with a circum-Antarctic
(11 species, ca. 42%) or West Antarctic (9 species, ca. 35%) distribution. Twenty-four (ca. 92%) are restricted to Antarctic
or Antarctic/sub-Antarctic waters; only two species have a wider distribution. Peter I Island hydroid fauna is composed of
typical representatives of the Antarctic benthic hydroid fauna, though it is characterized by the low representation of some
of the most diverse and widespread Antarctic genera (Schizotricha and Staurotheca). 相似文献

A new genus of the hydroid family Sertulariidae is established. Several species formerly assigned to the genus Symplectoscyphus Marktanner-Turneretscher, 1890 are included. A review of those species is given, including their main features along with some remarks. Two species new to science are added; the material of those species was collected in the Scotia Sea by the Spanish Antarctic Expedition “Antártida 8611”. Present autecological data are discussed. 相似文献

Chalicotheriids are rare in the late Miocene mammal localities of Axios Valley, Macedonia (Greece). The new campaign of excavations, since 1972, has provided some specimens, which are studied in this article. They are coming from two different localities. The late early Vallesian locality of Pentalophos 1 (PNT) has provided a skull and a mandible of an Ancylotherium. The morphological characters of the PNT material as the small size, the long snout, the shallow mandibular corpus, the strong cingulum in the teeth, the short tooth rows and the short M3/m3 indicate that it differs from the known Turolian species A. pentelicum and allow the erection of a new species, named Ancylotherium hellenicum n. sp., which can be used as a biostratigraphic marker of the Vallesian. The middle Turolian locality Prochoma 1 (PXM) has provided only one M3, which is determined to the chalicotheriine Anisodon macedonicus. This species was earlier described from the middle Turolian locality Vathylakkos 3 (VAT) and the late Turolian one of Dytiko 3 (DKO) of Axios Valley. The biogeography and biostratigraphy of the late Miocene chalicotheres of the Greco-Iranian Palaeoprovince (GRIP), as well as their palaeoecology are also discussed. The common chalicothere of GRIP is A. pentelicum, expanded from the Balkans to Afganistan and ranging stratigraphically from the early to the late Turolian. Chalicotherium goldfussi is certainly present in GRIP and it also ranges from the early to the late Turolian; its possible Vallesian occurrence needs confirmation. The other two late Miocene chalicotheres of GRIP A. macedonicus and Kalimantsia bulgarica are restricted to the Turolian of the Balkan Peninsula. 相似文献

The 17 species of the genus Cryptophagus Herbst known from Japan are analysed and revised. The opinions of different authors about the value of the characteristics of the external anatomy are contrasted, and an identification key and figures of the studied species are presented. Cryptophagus jaloszynskii sp. nov is described. Following a detailed study of the type material in different entomological collections, the status of taxa is revised and 3 new synonyms are proposed: Cryptophagus deceptor Grouvelle, 1919 and Cryptophagus longipennis Grouvelle, 1919 are syn. nov. for Cryptophagus dilutus Reitter, 1874 and Cryptophagus longiventris Grouvelle, 1919 syn. nov. for Cryptophagus latangulus Reitter, 1889. Cryptophagus elegans Grouvelle, 1919 resurrected from synonymy with Cryptophagus decoratus Reitter, 1874. A neotype is designated for Cryptophagus elegans Grouvelle, 1918; a lectotype and paralectotype is designated for 7 taxa: Cryptophagus decoratus Reitter, 1874; Cryptophagus deceptor Grouvelle, 1919; Cryptophagus grouvellei Bruce, 1938; Cryptophagus latangulus Reitter, 1889; Cryptophagus lewisi Reitter, 1874; Cryptophagus longior Grouvelle, 1919 and Cryptophagus longiventris Grouvelle, 1919. Cryptophagus zonatus Lyubarsky, 1995 previously known only from China is reported here for the first time from Japan. A key to all the species occurring in Japan is presented.www.zoobank.org/urn:lsid:zoobank.org:pub:7FF52749-590D-46F6-9794-1E2301906ECB 相似文献

The Phytosciara genus group (Diptera, Sciaridae: Phytosciara Frey, Dolichosciara Tuomikoski, and Prosciara Frey) are studied in the Korean peninsula. Dolichosciara koreaensis Shin & Menzel sp. n. is described and illustrated as new to science. Additionally, four species are reported as new to Korea: Dolichosciara orcina (Tuomikoski, 1960), Dolichosciara semiferruginea (Menzel, 1995), Prosciara producta (Tuomikoski, 1960), and Prosciara ussuriensis (Antonova, 1977). Identification keys are given for the genera of the Phytosciara genus group and for the Korean species of the genera Dolichosciara Tuomikoski and Prosciara Frey. The COI barcode for the new species is studied. 相似文献

This is the first study of caprellid amphipods from the coast of Papua New Guinea. Several collections from Madang Lagoon
(north) and Bootless Bay (south) have been studied. Seven species in seven genera are recorded, of which Pseudoproto papua sp. nov. is described as new to science. The genus Pseudoproto Mayer, 1903 has consisted, so far, of only one species, Pseudoproto fallax Mayer, 1903. Although only a single male has been found of Pseudoproto papua sp. nov., differences in antennae, mouthparts, gnathopod 2 and pereopods 3 and 4 have revealed that it represents a new species
of Pseudoproto. Lateral view figures of all species, together with a key to species level for the Caprellidea from Papua New Guinea are
also included.

Five new species (Gastrochilus yei, Gastrochilus minimus, Luisia simaoensis, Taeniophyllum xizangense, Tuberolabium subulatum) and two newly recorded species (Cleisostoma tricornutum, Luisia inconspicua) of Vandeae (Orchidaceae) from China are described and illustrated. Gastrochilus yei is similar to G. affinis and G. nepalensis, but differs from them by having an epichile not lobed, the apex of the hypochile not bilobed, and a tine on the apex of the leaf. Gastrochilus minimus is similar to G. acinacifolius, but can be distinguished from the latter by having a flabellate epichile that is densely hirsute on the adaxial surface and an inconspicuous central cushion; in addition, the hypochile of G. minimus has a keel that extends to the apex of the epichile. Taeniophyllum xizangense is similar to T. stella and T. radiatum, but it is distinguished from them by having much bigger flowers, inflorescences densely covered with short-bristly hairs, papillae on the external surface of sepals, and bigger triangular-ovate viscidium. Luisia simaoensis is similar to L. magniflora and L. ramosii, but can be easily distinguished from them by having lateral sepals longer than dorsal sepals and petals, lip with irregular and waved margins, and lip with bilobed apex. Luisia inconspicua is moved from Gastrochilus to Luisia based on phylogenetic analyses of plastid matK sequence data. Tuberolabium subulatum is similar to T. carnosum, but it can be easily distinguished from the latter by having an inflorescence much shorter than the leaves, yellow sepals and petals, and many small papillae outside the lip lobes. 相似文献

Four previously unknown species of hydromedusae are described from plankton samples collected during oceanographic cruises undertaken along the south-western coast of Africa. The Anthomedusa Bythotiara capensis sp.n., known from a single specimen, was found in shallow waters of the Cape region (South Africa). The Leptomedusa Margalefia intermedia gen. et sp.n. collected in Namibian waters, possesses desmoneme cnidocysts. This category of cnidocysts is previously unreported in the Leptomedusae, but is common in Anthomedusae and in the limnomedusan family Proboscidactylidae. Margalefia seems to occupy a position intermediate between the families Tirannidae and Laodiceidae. Two species of Limnomedusae, Aglauropsis edwardsii sp.n. and Proboscidactyla menoni sp.n. were frequent at several stations in Namibian waters between depths of 50 m and the surface. 相似文献
