Sphaeralcyon shackletonisp. nov. and Sphaeralcyon scottisp. nov. are described and illustrated from material collected at the Scotia Sea and Weddell Sea on the Polarstern cruises ANT XIX/3 (ANDEEP-I), ANT XIX/5 (LAMPOS), and ANT XXI/2 (BENDEX). With the discovery of Sphaeralcyon shackletoni and S. scotti, three species are now known in the genus Sphaeralcyon, all them reported from the Southern Ocean. The diagnosis of the genus has been slightly modified to accommodate some of the characters of the new species. 相似文献

The bryozoans from the Late Miocene bioherms of Cape Panagia (Taman Peninsula) that have previously been attributed to Membranipora lapidosa (Pallas, 1801) are shown to belong to a new genus, Tamanicella gen. nov., which comprises two species: T. lapidosa (Pallas, 1801) and T. panagiensis sp. nov. T. lapidosa is represented by two life forms. One of them is characterized by bilaminate (more rarely unilaminate) sheetlike colonies
with meandering lobes, and the other features erect branches. The lateral walls of each autozooecium in colonies of T. lapidosa have two multiporous septulae. T. panagiensis sp. nov. is characterized by massive multilaminate encrusting colonies and by the presence of three or four multiporous septulae
in the lateral walls. The genus Tamanicella is placed in the family Membraniporidae. The diagnosis of this genus is provided and its two species are described. 相似文献

Hymenochaete rhododendricola sp. nov. and Hymenochaete quercicola sp. nov. are described from Xizang Autonomous Region (Tibet), southwestern China. Hymenochaete rhododendricola is distinct in the genus by its large and heavily enmeshed setae, and growing on dead branches of Rhododendron. Hymenochaete quercicola differs from other species by its smooth or tuberculate hymenophore, presence of a cortex, relatively large and oblong‐ellipsoid basidiospores, and living on dead branches of Quercus. 相似文献

Mesogligorgia scotiae gen. nov., sp. nov. is described and illustrated from a colony collected in the Scotia Sea, 2,201–2,213 m in depth, on the
ANDEEP-I cruise. The new taxon is placed in the family Plexauridae because of: 1) the presence of a horny axis with a cross-chambered
central core and numerous loculi, 2) retractile polyps in calyces with distinct spicular components, and 3) armed polyps with
large sclerites with a poorly- developed collaret and eight well-developed points. The irregularly distributed sclerites running
along the axis, into a thick mesogloeal coenenchyme, and the elongated spindles with irregular ends are the most distinctive
characters of the newly proposed genus. 相似文献

A new monotypic genus Cosmosycanus is established for Agriosphodrus perelegans Breddin, 1903. This genus is separable from Agriosphodrus Stål, 1867 by the head being much longer than the pronotum, and the posterior pronotal lobe lacking a median depression. The new genus is also distinguished from Sycanus Amyot and Serville, 1843 by the smooth posterior pronotal lobe and the unspined and non‐tuberculate scutellum. The type species, Cosmosycanus perelegans, comb. nov. is redescribed and considered the senior synonym of Sycanus elongatulus Distant, 1919. 相似文献

The family Subergorgiidae comprises two genera, Subergorgia with three species and Annella with two species. All the previously known species are distributed in tropical and subtropical waters from the northern Red
Sea to the central Pacific. The presence of a subergorgiid in Antarctic waters could support the hypothesis that at least
part of the Antarctic fauna has its origin in the Cretaceous period, when Antarctica was part of the Gondwana continent. The
new genus Rosgorgia with the new species inexspectata is placed in the family Subergorgiidae by the presence of smooth, fusiform and often anastomosing needles in the axis, wart
spindles in the coenenchyme, and coelenteric cavities of polyps only present in the coenenchyme. The genus Rosgorgia differs from Subergorgia and Annella by the presence of tuberculate rods in the axis. It is further distinguished from Annella by the absence of double-disk sclerites in the coenenchyme, and not anastomosing branches.

Based on a recent fieldwork in Panama, 25 species of rust fungi and several new hosts are reported for the first time from
this country. Among the new records is one new species, Dicheirinia panamensis on Cojoba rufescens (Fabaceae). It differs from known species in the genus Dicheirinia by the presence of uredinia and telia without paraphyses, irregularly tuberculate urediniospores with two germ pores on the
flattened sides, and tuberculate teliospores formed by three probasidial cells, subtended by a pedicel with three hyaline,
apical cells.

Abstract This paper reports a new subfamily, a new genus and a new species, that is, Pacrinae subfam. nov., Pacris gen. nov and Pacris xizangensis sp. nov in Gomphoceridae. The new subfamily is allied to Orinhippinae of Gomphoceridae and it differs from the latter by wings and tympanum absent. The new genus is similar to Orinhippus Uvarov, 1921 but differs from the latter in: (i) foveolae absent; (ii) tegmina absent; (iii) tympanum absent; (iv) hind margin of pronotum with incised in the middle. Type specimens are deposited in the Museum of Hebei University, Baoding, China. 相似文献

Sinodima gen. nov., a new genus in the click-beetle tribe Dimini Candèze, 1863 from the mountains in Hunan, China, is described and figured here to accommodate S. jenisi sp. nov. The new genus is easily recognizable from all other Dimini by the following combination of characters: short antennomeres II and III; transverse pronotum with inconspicuous anterior angles; arcuate prosternal process; mesoventrite with straight frontal margin and oblique and straight sides; absent hind wings; and absent sclerites or spines in the bursa copulatrix. Additionally, we compare Sinodima gen. nov. with the morphologically similar genera, and discuss the systematic position of this genus within Dimini.www.zoobank.org/urn:lsid:zoobank.org:pub:91F22A25-E1F1-4EC4-B3EF-5D632B83FDE5 相似文献

Summary The genus Ornithocheyletia Volgin, 1964 is revised. If the three species described below are included the number of known species in this genus is now 22. These species live on or in the skin of birds and produce mange. The holotypes of all these species have been examined except those of O. pinguis (Berlese) and of O. dubinini Volgin which were not available. Three new species and one new subspecies are described: O. geopeliae sp. nov. from Geopelia striata, O. lepidus sp. nov. from Garrulax leucolophus bicolor, O. eulabes from Eulabes javana and O. psittaci poicephali ssp. nov. from Poicephalus senegalus. O. similis Fain, 1972 is placed as a subspecies of O. hallae Smiley, 1970. The genus Ornithocheyletia is redefined and a key to the species is provided. The following stages have been observed in the life cycle: egg—prelarva—larva— protonymph—tritonymph—adults. A prelarva is observed for the first time: it is represented by a small ecdysis organ consisting of two small bifid sclerites serving for the rupture of the eggshell. The adult female develops into a tritonymph, the adult male into a protonymph. The males are either homeomorphic or heteromorphic; the latter are characterized by the hypertrophy and modification of the gnathosoma, especially the palps. ac]19800531 相似文献

Molecular phylogenetic evidence indicates that the octocoral family Alcyoniidae is highly polyphyletic, with genera distributed across Octocorallia in more than 10 separate clades. Most alcyoniid taxa belong to the large and poorly resolved Holaxonia–Alcyoniina clade of octocorals, but members of at least four genera of Alcyoniidae fall outside of that group. As a first step towards revision of the family, we describe a new genus, Parasphaerasclera
gen. n., and family, Parasphaerascleridae fam. n., of Alcyonacea to accommodate species of Eleutherobia Pütter, 1900 and Alcyonium Linnaeus, 1758 that have digitiform to digitate or lobate growth forms, completely lack sclerites in the polyps, and have radiates or spheroidal sclerites in the colony surface and interior. Parasphaerascleridae fam. n. constitutes a well-supported clade that is phylogenetically distinct from all other octocoral taxa. We also describe a new genus of Alcyoniidae, Sphaerasclera
gen. n., for a species of Eleutherobia with a unique capitate growth form. Sphaerasclera
gen. n. is a member of the Anthomastus–Corallium clade of octocorals, but is morphologically and genetically distinct from Anthomastus Verrill, 1878 and Paraminabea Williams & Alderslade, 1999, two similar but dimorphic genera of Alcyoniidae that are its sister taxa. In addition, we have re-assigned two species of Eleutherobia that have clavate to capitate growth forms, polyp sclerites arranged to form a collaret and points, and spindles in the colony interior to Alcyonium, a move that is supported by both morphological and molecular phylogenetic evidence. 相似文献

A survey of xeniid octocorals was carried out in the waters off Southwestern Thailand in September, 2007. Microscopic investigation of the colonies revealed that three specimens belonged to the genus Ovabunda. Gross morphological examination is presented here accompanied by scanning electron micrographs of the sclerites. Molecular phylogenetic analysis showed identical genotypes at mtMutS, COI, and 28S rDNA for all three specimens and supports their generic assignment. Colony size and shape, sclerite size, and pinnule arrangement differ from nominal species of Ovabunda and thus a new species, O. andamanensis is introduced here. This work also presents a new eastern geographical record for the genus Ovabunda. 相似文献

Callorhynchocotyle hydrolagi n. sp. is proposed for hexabothriids found on the gills of the ghost shark, Hydrolagus ogilbyi, taken off the coast of southeastern Australia. The species is distinguished from the three previously described species of the genus in that the sclerites and the points of the sclerites of the three sucker pairs are all of similar size. The greater thickness of the sucker sclerites, the hamuli with inflated, almost spherical terminations of the roots, and the robust male copulatory complex also serve to differentiate C. hydrolagi. 相似文献

Stephanthus antarcticus gen. nov. et sp. nov. is described and illustrated from six specimens collected in the Antarctic Peninsula on the Polarstern cruises ANT XV/3 and ANT XIX/3. The new genus is characterised by the absence of sphincter and basilar musculature, the presence of a single strong siphonoglyph with a basal enlargement, distinct parietobasilar musculature, tentacles without acrospheres, two cycles of six pairs of mesenteries (only one of them perfect), and a deep fosse with parapet; another remarkable feature is the absence of microbasic p-mastigophores. The new genus shows characteristics of three families of soft-bottom-dwelling sea anemones, namely Haloclavidae Verrill, 1899, Halcampoididae Appellöf, 1896, and Andresiidae Stephenson, 1922. The generic characters of Stephanthus gen. nov. are discussed and it is tentatively placed in the family Haloclavidae. 相似文献

Maemonstrilla gen. nov. , known exclusively from females, is proposed for Monstrilla longipes A. Scott, 1909, M. turgida A. Scott, 1909, and five new species from coral reef plankton in the Ryukyu Islands, Japan: Maemonstrilla hyottoko sp. nov. (type species), M. polka sp. nov. , M. spinicoxa sp. nov. , M. simplex sp. nov. and M. okame sp. nov. A syntype of M. turgida was examined, but the holotype of M. longipes is lost; the latter species, being similar to several of the new species, is regarded as unidentifiable, and the identity of specimens assigned to it by several authors is put in doubt. Until now, all known female monstrilloids have had posteriorly trailing ovigerous spines, but in Maemonstrilla gen. nov. these spines point anteriorly and hold the egg mass between the legs beneath the thorax. This is the first known instance of subthoracic brooding in a planktonic copepod; its functional significance is discussed, and brooding habits of non‐planktonic copepods are briefly reviewed. The intercoxal sclerites of legs 1–4 in Maemonstrilla gen. nov. are very wide, making room for the eggs. In all species except M. turgida comb. nov. , the inner seta of the proximal segment of each leg ramus is either absent or reduced to a nub; this may lessen interference of the egg mass with leg movement. All species have a uniramous leg 5 with two setae, except M. turgida comb. nov. (biramous with setae on both rami); M. turgida comb. nov. is evidently the sister‐group of its congeners, each sister‐group in the genus being defined by additional autapomorphies. Scanning electron micrographs of all the Ryukyuan species except M. simplex sp. nov. are provided; these constitute a preliminary survey of monstrilloid integumental organs and cuticular ornamentation. Among the unusual features are two lobes at the base of the coxa in legs 1–4 of M. polka sp. nov. and M. spinicoxa sp. nov. and two pairs of posterodorsal spine‐like scales on the first and second free pedigers of M. turgida comb. nov. Newly hatched nauplii of M. okame sp. nov. , examined by scanning electron microscopy, are generally similar to those of Monstrilla hamatapex Grygier & Ohtsuka, 1995, but with a different mandibular structure in which the distal hook and seta clearly represent the endopod, not enditic armament of the basis. © 2008 The Linnean Society of London, Zoological Journal of the Linnean Society, 2008, 152 , 459–506. 相似文献

Diverse radiolarians from the Upper Cretaceous Perapedhi and Moni formations (southern Cyprus) are studied. Many representatives
of the genus Afens Riedel et Sanfilippo, 1974 are recognized. The diagnosis of the genus Afens is emended and three new species of this genus, Afens perapediensis sp. nov., Afens moniensis sp. nov., and Afens concinnus sp. nov., are described. In addition, the species Afens liriodes Riedel et Sanfilippo, 1974 is redescribed. 相似文献
