Vuilleminia nilsii sp. nov. is described based on collections made in Argelès-sur-Mer communal forest, France. It is characterized by a resupinate, smooth, whitish, decorticating basidiocarp, cylindrical cystidia, heavily crystallized matrix, and guttulate, allantoid spores. It can be distinguished from V. coryli by basidiospore size, substrate preferences, abundance of dendrohyphidia, and crystal in the context. Phylogenetic analyses place Vuilleminia ericae, Dendrothele dryina (= V. dryina) and Dendrothele maculata in a distinct, well-defined clade. The new genus Dendrominia is proposed for this clade. The new combinations Dendrominia dryina, D. ericae, and D. maculata are proposed. Dendrothele corticola is regarded as a synonym of D. maculata. A lectotype is selected for V. macrospora. An updated key to the genus Vuilleminia and a key to Dendrominia species are provided.  相似文献

The species of the genus Charisius Champion, from Mexico and Central America are reviewed. The flightless genus Narses Champion, with one included species, N. subalatus Champion, is placed in synonymy with the genus Charisius. Four new species are described and illustrated, C. granulatus and C. punctatus (from Guatemala) and C. apterus and C. howdenorum (from Mexico). Charisius subalatus (Champion) is redescribed and illustrated. The species C. interstitialis Champion is placed in synonymy with C. zunilensis Champion. The genus is redescribed to include the four new species and N. subalatus. New distributional records are presented for all other species of the genus and a revised key is presented for identification of all the species of the genus.  相似文献

We investigated a previously unidentified subaerial corticolous strain of the genus Elliptochloris Tschermak-Woess. The alga shares the generic morphological characters with Elliptochloris bilobata, the type species of the genus, but it has a thicker cell wall of adult globular cells, different chloroplast structure and it also differs in shape of elliptical autospores. The differences of the autospore shape between both species were evaluated using landmark-based geometric morphometrics. The 18S rDNA gene sequence of the new alga forms a monophyletic clade with the authentic strain of E. bilobata within the green algal class Trebouxiophyceae close to representatives of the genus Coccomyxa. We describe the new alga as Elliptochloris bilobata var. corticola var. nov. Presented at the International Symposium Biology and Taxonomy of Green Algae V, Smolenice, June 26–29, 2007, Slovakia.  相似文献

The roaker species (Sciaenidae) Sciaena impropria Gabelaia, 1976 from the Lower Pliocene (?) of Abkhazia is assigned to a new genus, Carnevalella gen. nov. This genus essentially differs from other sciaenid fishes in the greater number of supraneurals and vertebrae, the posterior shift of the dorsal fin origin, and the fusion of the fourth hypural with the terminal centrum. An incomplete roaker skeleton found in the Upper Maeotian (Upper Miocene) of the Taman Peninsula (Krasnodar Region) is assigned to the same genus. The Maeotian roaker is described as a new species, C. (?) tmutarakanica sp. nov. Morphological peculiarity of the genus Carnevalella gen. nov. justifies its allocation to a new subfamily, Carnevalellinae subfam. nov.  相似文献

A new genus of soft coral from the Republic of Congo is described, Complexum gen. n. Nine West African octocoral species previously described in the genus Alcyonium by Tixier-Durivault (1955) are referred to this new genus, and a new species is described and figured, Complexum pusillum sp. n. The new species is characterized by having encrusting growth form and abundant spiny clubs in the surface of the polyparium. It colonizes shallow calcareous rocky banks (5 to 20 m depth) existing in coastal water of the region of Pointe-Noire. Based on molecular phylogeny this new genus is well separated from Alcyonium species.  相似文献

Oligotrophic fungi can grow on carbon-free media. Most of the currently known oligotrophic fungi were reported from soil. Plectosphaerella oligotrophica sp. nov. was recently isolated from soil in China using a low carbon medium. The new species is morphologically characterized by pale yellow colonies on PDA, phialidic conidiogenous cells, and hyaline, ellipsoidal and 0–1-septate conidia. Phylogenetic analysis based on internal transcribed spacer (ITS) and large subunit (LSU) rDNA sequences confirmed the placement of P. oligotrophica as a new species in the genus Plectosphaerella. The new species is compared to the morphologically and phylogenetically closely related species. Beta-tubulin fragments from the new species were also sequenced and deposited in GenBank. A key to the currently accepted species of the genus is provided.  相似文献

The new deep-sea copepod species of the family Paramesochridae (Copepoda, Harpacticoida) presented here was collected during the scientific ANtarctic benthic DEEP-sea biodiversity cruise II (ANDEEP II) to the Weddell Abyssal Plain and western Weddell Sea and the CROZet natural iron bloom and EXport experiment (CROZEX cruise) to the Crozet Isles in the Indian Ocean. The new species has been allocated to the subgenus Wellsopsyllus within the genus Wellsopsyllus Kunz, 1981, based on the 1-segmented endopods and 3-segmented exopods of swimming legs 2–4. Furthermore, the new species shows a 1-segmented exopod of the antenna. Wellsopsyllus (W.) antarcticus sp. n. can be distinguished from its congeners by its small body size, the presence of two setae on the distal segment of the endopod of the first swimming leg, by the very small furcal rami, the extremely reduced endopods of second and third swimming legs, the reduced mandibular palp and maxillula, as well as by the size and armature of the fifth and sixth swimming legs in both sexes. Difficulties of the placement of the new species into a suitable genus show an insufficiency in the present family classification. In the future, a revision of the genus Wellsopsyllus is essential. With its presence in the western Weddell Sea and the Indian Ocean, the new species may have a wide distribution range. Furthermore, it is the first abyssal species of the genus Wellsopsyllus sampled outside of the Scotia Sea.  相似文献

A new species of the lampyrid genus Oculogryphus Jeng, Engel, and Yang, O. shuensis sp. n. from China (Sichuan Province) is described and figured. The genus previously was known only from Vietnam, and the new species is the first representative of the genus in the Sino-Japanese zoogeographic realm. Some morphological variations of Oculogryphus and the allied genus Stenocladius are discussed and a modification to the most recent key to ototretine genera is proposed to accommodate Oculogryphus.  相似文献

The genus Scleropteroides Colonnelli, 1979 (Ceutorhynchinae: Scleropterini) was revised on the basis of detailed morphological observations. The genus was redefined to include three species from East Asia: S. hypocrita (Hustache, 1916) is redescribed and recorded from northeastern China and northern Korea for the first time; S. horridulus (Voss, 1958) is redescribed with new records from southern Korea; S. insularis Voss, 1971 was moved from synonymy with S. hypocrita to that with S. horridulus (syn. n.), and S. longiprocessus Huang & Yoshitake, sp. n. is described as new, sympatric with S. hypocrita in Japan. All the species are associated with woody Rubus species (Rosaceae). A key to species, habitus photographs, illustrations of important characters, and distribution maps are provided for each species.  相似文献

A new stem dugongid species, Prototherium ausetanum sp. nov. (Dugongidae, Halitheriinae), is described based on a cranium from the middle Eocene of Mas Vilageliu (Tona, NE Iberian Peninsula). The new species displays a combination of features that enables its distinction from other halitheriines, including Prototherium veronense (type species of the genus), Prototherium? intermedium (which likely belongs to a different genus), and Prototherium? montserratense (here considered a nomen dubium), as well as Eotheroides spp. In overall morphology (e.g., dolichocephaly) the new species more closely resembles species previously included in Prototherium. However, a cladistic analysis based on craniodental features recovers the new species as the sister taxon of Eotheroides aegyptiacum (type species of this genus), further constituting a polytomy with P. veronense, Eotheroides lambondrano and the remaining Halitheriinae. Our analysis further indicates that P.? intermedium is more derived than other species of Prototherium, but it does not conclusively resolve the phylogenetic relationships between the included species of Prototherium and Eotheroides. A deeper taxonomic revision of these two genera would be required in order to better resolve the phylogeny of early dugongids.  相似文献

The theca and the columnals of twenty-two lateCretaceous species of the genus Bourgueticrinus (including two new species), of one species of the genus Democrinus, of four species of the genus Conocrinus (including one new species) and of one species of the genus Paleobathycrinus known from USSR are figured and shortly described. Biometric reconstructions of stems for B. aequalis, B. bellus, B. danicus, B. fischeri and C. tauricus nov. sp. are given. A new index is used to suggest the relative flexibility of stem. Decrease in dimension and flexibility of the arms in several species take place simultaneously with an increase of stem flexibility. This fact seems to be closely related to environmental changes.  相似文献

The genus Eretmophyllum, a characteristic and widespread taxon of the order Ginkgoales, is restricted in the Mesozoic floras of Eurasia. In China, although some specimens were assigned to Eretmophyllum based on gross leaf morphology, none have epidermal structure, which is essential for species delimitation within this genus. In this paper, we describe a new species, Eretmophyllum neimengguensis n. sp., from the Middle Jurassic Yan’an Formation of the Ordos Basin, China. This is the first record of the genus Eretmophyllum (Ginkgoales) from the Ordos Basin as well as from China based upon the gross leaf morphology and the epidermal structure. The new record significantly extends the stratigraphic and geographic distribution of Eretmophyllum in China and Eurasia. It also improves our understanding of its leaf morphology, epidermal structure, and past diversity. The taxonomic position and the stratigraphic and geographical range of the genus Eretmophyllum are discussed. Briefly, leaf morphological and epidermal characters of the new species, associated plant assemblages, and sedimentology indicate that the regional climate of the Ordos Basin was warm and humid with seasonal temperature and precipitation fluctuations in warm-temperate zone during the Middle Jurassic. Furthermore, given the relationship between the distribution/diversity of the genus and the climate, the genus Eretmophyllum may be confined to the warm-temperature climate, is intolerant of heat and frost, and can be considered as an indicator of humid and warm climatic conditions.  相似文献

The present paper is the third part of a revision of the fauna of the Volga Area. Five species new for the Volga Area, including four new for Russia are recorded. Nudicauda gen. n. is erected with type species Nudicauda nigra (Matesova, 1957) (comb. n.). The new genus differs from other genera of mealybugs in a complex of characters and mainly in the presence of very specific oral rim tubular ducts with a broad flat ring and in an unusual ovisac with the opening over posterior tergites of the female body. In addition to the type species, N. orientalis (Borchsenius, 1949) and N. salina (Matesova, 1981) (comb. n.) are also included in the new genus. N. nigra and N. orientalis are considered as separate species, contrary to Danzig (1980). All the three species of the new genus are redescribed and illustrated. The structure of the tubular ducts of the genus Humococcus Ferris, 1953 is briefly discussed and illustrated.  相似文献

Four new species and a new genus of lucinid bivalves are described from shallow and deeper waters in the Indian and West Pacific Oceans. The new genus Scabrilucina (subfamily Lucininae) includes the little-known Scabrilucina victorialis (Melvill, 1899) from the Arabian Sea and Scabrilucina vitrea (Deshayes, 1844) from the Andaman Sea as well as a new species Scabrilucina melvilli from the Torres Strait off northeastern Australia. Ferrocina brunei new species (Lucininae) was recovered from 60 m near oil drilling activities off Borneo; its anatomy confirmed the presence of symbiotic bacteria. Two unusual deeper water species of Leucosphaerinae are described, both species included in on-going molecular analyses; Gonimyrtea ferruginea from 400–650 m in the southwest Pacific and Myrtina reflexa from 200–825 m off Zanzibar and Madagascar.  相似文献

The genus Paramunida belongs to the most diverse family of galatheoids and it is commonly reported from the continental slope across the Indian and Pacific Oceans. Examination of material collected by the NOAA RV Townsend Cromwell Cruise near Christmas (Kiritimati) Island, Kiribati, revealed the existence of a new species of Paramunida (P. haigae), which represents the fourth record of the genus for the Central Pacific. Furthermore, recent efforts to unravel phylogenetic relationships and diversification patterns in Paramunida revealed P. granulata (Henderson, 1885) to be the most basally diverging taxon within the genus. This species is clearly distinguished from other species of Paramunida by the spinulation of the carapace and the length of the distomesial spine of the second antennal peduncle article, which in combination with a high level of genetic divergence suggest that this species represents a separate monotypic lineage. A new genus, Hendersonida gen. n., is proposed to accommodate this species based on morphological and molecular evidence. An updated dichotomous identification key for all species of Paramunida is presented.  相似文献
