A new species, Metapochonia hahajimaensis is proposed. Three isolates were obtained from soil samples collected from Hahajima, Ogasawara Islands, Tokyo, Japan. Using a combination of morphological characteristics and multigene (ITS, SSU, LSU, TEF) phylogenics, the isolates were identified as a Metapochonia species which were previously undescribed. The new species is distinguished from the closely-related M. bulbillosa and M. goniodes or other Metapochonia taxa by conidial size and colonial characteristics.  相似文献

Among the genera of the subfamily Scorpiopinae Kraepelin, 1905 Alloscorpiops remains rather discrete. Only recently new species were added to this genus, increasing its number from two to five. Therefore, species of Alloscorpiops remain rare. One remarkable new species, Alloscorpiops troglodytes sp. n., is described on the basis of a single male specimen collected inside a cave from Song Thanh Nature Reserve, Cha Vanh Commune, Nam Giang District in Vietnam. The new species presents most features exhibited by scorpions of the genus Alloscorpiops, but it is characterized by reduced size, slender body and elongated pedipalps. This new scorpion taxon represents the third species of Scorpiopinae discovered in a cave system, and may be another endemic element in the fauna of Vietnam.  相似文献

The Tribe Hemilophini (Lamiinae) is reviewed for Hispaniola and an identification key is provided. Fifteen species are now known from the island, including one new species of Adesmus (Adesmus fortunei from Pedernales and La Vega Provinces, Dominican Republic), one new species of Oedudes (Oedudes anulatus from Peravia and La Vega Provinces, Dominican Republic), and five new species of Calocosmus (Calocosmus contortus from San Cristóbal Province, Calocosmus punctatus from Peravia Province, Calocosmus rawlinsi from Elías Piña Province, Calocosmus robustus from La Vega Province, and Calocosmus thonalmus from La Altagracia Province, all in the Dominican Republic). Oedudes and Adesmus are new island and country records for Hispaniola and Dominican Republic, respectively. Calocosmus holosericeus Gahan is a new synonym of Calocosmus janus Bates. In addition to the new species, five new country records and four new island records are presented for Calocosmus.  相似文献

A new species of Noblella is described from the humid montane forest of the Región Cusco in Peru. Specimens were collected at 2330–2370 m elevation in Madre Selva, near Santa Ana, in the province of La Convención. The new species is readily distinguished from all other species of Noblella by having a broad, irregularly shaped, white mark on black background on chest and belly. The new species further differs from known Peruvian species of Noblella by the combination of the following characters: tympanic membrane absent, small tubercles on the upper eyelid and on dorsum, tarsal tubercles or folds absent, tips of digits not expanded, no circumferential grooves on digits, dark brown facial mask and lateral band extending from the tip of the snout to the inguinal region. The new species has a snout-to-vent length of 15.6 mm in one adult male and 17.6 mm in one adult female. Like other recently described species in the genus, this new Noblella inhabits high-elevation forests in the Andes and likely has a restricted geographic distribution.  相似文献

Two new species of yellow-shouldered bats Sturnira Gray, 1842 (Chiroptera, Phyllostomidae) from Central America and western South America are described using molecular and morphological data. The two new species, which occur in Costa Rica and Panama and in western Ecuador, were previously confused with S. ludovici, and S. lilium and S. luisi, respectively. Sturnira now includes 22 described species, making it the most speciose genus in the Neotropical family Phyllostomidae.  相似文献

Three new eriophyid species (Phyllocoptinae), Shevtchenkella denticulata sp. n., Notallus pestehae sp. n. and Echinacrus ruthenicus sp. n., were described from Eryngium thyrsoideum Boiss. (Apiaceae), Pistacia vera L. (Anacardiaceae) and Lycium ruthenicum Murray (Solanaceae), respectively. All the three new species were collected from southwest of the East Azerbaijan province, Iran in 2011. It is the first record of an eriophyoid mite collected from E. thyrsoideum and L. ruthenicum and the first record of Notallus from Anacardiaceae plant family.  相似文献

Seven species of bees from the eastern United States, representing four families in the Apoidea, were dissected and examined for nematode associates. Dufour''s glands in females of Halictus ligatus, Augochlora pura mosieri, and Augochlorella gratiosa (Halictidae) from Florida were infested with dauer juveniles of Aduncospiculum halicti (Diplogasteridae). The Dufour''s glands of Colletes thoracicus (Colletidae) females from Maryland were infested with dauer juveniles of a new species of Koerneria sp. (Diplogasteridae), and abdominal glands of females of Andrena alleghaniensis (Andrenidae) from New York were infested with dauer juveniles of another new species of Koerneria. The lateral and median oviducts, Dufour''s glands, and poison sacs in females of Anthophora abrupta (Anthophoridae) from Maryland and Alabama were infested with dauer juveniles of a new species of Bursaphelenchus sp. (Aphelenchoididae). Cross sections of the nematode-infested poison sacs of A. abrupta revealed two types of humoral host defense reactions.  相似文献

We describe a new species of Telmatobius from the Pacific slopes of the Andes in central Peru. Specimens were collected at 3900 m elevation near Huaytará, Huancavelica, in the upper drainage of the Pisco river. The new species has a snout–vent length of 52.5 ± 1.1 mm (49.3–55.7 mm, n = 6) in adult females, and 48.5 mm in the single adult male. The new species has bright yellow and orange coloration ventrally and is readily distinguished from all other central Peruvian Andean species of Telmatobius but Telmatobius intermedius by having vomerine teeth but lacking premaxillary and maxillary teeth, and by its slender body shape and long legs. The new species differs from Telmatobius intermedius by its larger size, flatter head, and the absence of cutaneous keratinized spicules (present even in immature females of Telmatobius intermedius), and in males by the presence of minute, densely packed nuptial spines on dorsal and medial surfaces of thumbs (large, sparsely packed nuptial spines in Telmatobius intermedius). The hyper-arid coastal valleys of Peru generally support low species richness, particularly for groups such as aquatic breeding amphibians. The discovery of a new species in this environment, and along a major highway crossing the Andes, shows that much remains to be done to document amphibian diversity in Peru.  相似文献

Six species of terrestrial isopods from the province of Qazvin, central Iran, are recorded. Three species, Hemilepistus klugii (Brandt, 1833), Protracheoniscus ehsani Kashani, 2014 and Mongoloniscus persicus Kashani, 2014, were previously reported from the province. Hemilepistus elongatus Budde-Lund, 1885 and Protracheoniscus major (Dollfus, 1903) are recorded for the first time, and one species, Protracheoniscus sarii sp. n., is described as new. The diagnostic characters of the new species are figured.  相似文献

Three new plant constituents were isolated from the primary leaves of Vigna radiata (= Phaseolus aureus) and their structures elucidated and characterized with the aid of negative-ion fast atom bombardment mass spectrometry (FAB MS), 1H NMR and UV spectroscopy, thin-layer, gas-liquid and high performance liquid chromatography. The new conjugates are (E)-p-coumaroyl-, (E)-caffeoyl- and (E)-feruloyltartronic acids. Their structures were unequivocally confirmed by comparison with synthetic material. The metabolism of the new hydroxycinnamic acid conjugates in young plants of Vigna radiata is described.  相似文献

The subgenus Tinotus Sharp, 1833, stat. n., of the genus Aleochara Gravenhorst, 1802 (Aleocharini: Aleocharina) from Japan, Taiwan, and the Russian Far East is revised. Tinotus is a new record from the latter two regions. Three species are recognized: Aleochara (Tinotus) morion Gravenhorst, 1802, comb. n. [Japan (new record), the Russian Far East (new record)], Aleochara (Tinotus) eoa nom. n. [replacement name for Tinotus japonicus Cameron, 1933; Japan, Taiwan (new record)], and Aleochara (Tinotus) takashii sp. n. (central Honshû, Japan). The systematic position of Tinotus is discussed. All species are (re-)described, keyed, and figured. A world checklist of Tinotus species, comprising 40 valid species, is provided in an appendix. Additional taxonomic changes are proposed, including a new synonymy, a revalidation, 13 new replacement names, and 27 new combinations.  相似文献

This study describes the design and evaluation of a portable bright-field and fluorescence microscope that can be manufactured for $240 USD. The microscope uses a battery-operated LED-based flashlight as the light source and achieves a resolution of 0.8 µm at 1000× magnification in fluorescence mode. We tested the diagnostic capability of this new instrument to identify infections caused by the human pathogen, Mycobacterium tuberculosis. Sixty-four direct, decontaminated, and serially diluted smears were prepared from sputa obtained from 19 patients suspected to have M. tuberculosis infection. Slides were stained with auramine orange and evaluated as being positive or negative for M. tuberculosis with both the new portable fluorescence microscope and a laboratory grade fluorescence microscope. Concordant results were obtained in 98.4% of cases. This highly portable, low cost, fluorescence microscope may be a useful diagnostic tool to expand the availability of M. tuberculosis testing at the point-of-care in low resource settings.  相似文献
