Two new species of the genus Melanostoma Schin., 1860, closely related to M. dubium (Zetterstedt, 1838), are described, and a key to the species of this group is given. Melanostoma clausseni sp. n. and M. tschernovi sp. n. are closely related to M. dubium (Zett.), but differ in the uniformly black abdomen and legs. Melanostoma clausseni sp. n. differs from M. tschernovi sp. n. in the lustrous mesonotum and finely pruinose frons and face (in M. tschernovi, the face, frons, and mesonotum are covered with gray pruinosity). Holotypes of the new species are deposited in the collection of the Siberian Zoological Museum (Novosibirsk).  相似文献

Five new species, Petrobius caucasicus sp. n., Trigoniophthalmus presimplex sp. n., T. divnogorski sp. n., T. kislovodski sp. n., and T. adigei sp. n. (Machilidae), are described from the Caucasus. A key to all the known species of the genus Trigoniophthalmus is given. Two subgenera (Trigoniophthalmus s. str., Trigoniocellus subgen. n.) in the genus Trigoniophthalmus are described. 2 + 2 retractile vesicles are present on abdominal segments II–IV in the species of Trigoniocellus subgen. n. and on II–V abdominal segments in Trigoniophthalmus s. str. Analysis of the evolution and phylogenetic relations between the species of the genus Trigoniophthalmus is performed for the first time. The formation of bristletails of the genus Trigoniophthalmus appears to occur in the Caucasian mountain province of the European area, from where they penetrated to the Central European mixed province and the Mediterranean subarea. Among the described species of the genus, T. kislovodski is distinguished by the greatest number of plesiomorphic states of morphological characters.  相似文献

Ogataea parapolymorpha sp. n. (NRRL YB-1982, CBS 12304, type strain), the ascosporic state of Candida parapolymorpha, is described. The species appears homothallic, assimilates methanol as is typical of most Ogataea species and forms hat-shaped ascospores in asci that become deliquescent. O. parapolymorpha is closely related to Ogataea angusta and Ogataea polymorpha. The three species can be resolved from gene sequence analyses but are unresolved from fermentation and growth reactions that are typically used for yeast identification. On the basis of multiple isolates, O. angusta is known only from California, USA, in association with Drosophila and Aulacigaster flies, O. parapolymorpha is predominantly associated with insect frass from trees in the eastern USA but O. polymorpha has been isolated from various substrates in the USA, Brazil, Spain and Costa Rica.  相似文献

Three new beetle species of the formal genus Artematopoides, i.e., A. maximus sp. nov., A. crispulus sp. nov., and A. lepidus sp. nov., from the Mongolian Shar-Teg locality are described. Early Jurassic Ovivagina propinqua Zhang, 1997, O. prolixa Zhang, 1997, and O. insculpta Zhang, 1997 from the Junggar Basin (Xinjiang, China) and Middle Jurassic Sinonitidulina longa Hong, 1983 from the Zhouyingzi locality (Hebei, China) are transferred to Artematopoides, and the three species from Xinjiang are redescribed. Ovivagina immediata Zhang, 1997 is synonymized with O. insculpta Zhang, 1997. A new name, Artematopodites leskoviensis Yan, nom. nov., is proposed for A. longus Ponomarenko, 1990, which proved to be a junior secondary homonym of A. longa (Hong, 1983).  相似文献

The genus Phrixolepia Butler, 1877 is revised and its diagnosis is given. At present, the genus comprises 10 species, three of which are described as new (all the holotypes and paratypes are deposited in MWM): Ph. pudovkini Solovyev, sp. n., LT: “China, Shaanxi prov., Taibai Shan, Tsinling Mts., Houzhenzi, 33°53′ N; 107°49′ E, 1500 m,” genital slide 11389; Ph. sinyaevi Solovyev, sp. n., LT: “N. Vietnam, Cuc. Phuong, 60 km SW Hanoi, 20°15′ N; 105°20′ E, 400 m,” genital slide 11386; Ph. nigra Solovyev, sp. n., LT: “China, prov. Yunnan, Yunlong, Fengshuining Mts., 13 km N of Caojian, 2460 m,” genital slide 11391. All the species are very similar externally, except for differences in size, tints of the coloration, and the presence of a semi-ovoid bright apical spot in the fore wing. The features of the male genitalia are diagnostic. A key to the species is given. The phylogenetic relationships between the species are examined. The genus is closely related to Olona Snellen, 1900 and Phobetron Hübner, 1825, based on the characters of larval morphology. A similar larval morphology also found in the family Dalceridae could be a synapomorphy of the families Limacodidae and Dalceridae.  相似文献

 A new species of Erysiphe sect. Uncinula is described and illustrated from Patagonia, Argentina. Erysiphe patagoniaca sp. nov., found on leaves of Nothofagus × antarctica, is similar to E. nothofagi and E. kenjiana, but differs in its appendages being twisted throughout their length and the number of appendages, asci, and ascospores. The two endemic species of Erysiphe sect. Uncinula, E. magellanica and E. nothofagi, coexisted on the same leaves together with Erysiphe patagoniaca. Received: September 19, 2002 / Accepted: November 28, 2002 Acknowledgments The authors are grateful to Ms. Seiko Niinomi for providing the micrographs of ascomata of Erysiphe spp. on Nothofagus.

Four new xarifiid copepods are described. They were found in association with the scleractinian coral Pavona explanulata (Lamarck) occurring in shallow water reefs off Yenliao in northern Taiwan. The four species are: Xarifia capillata n. sp., X. parva n. sp., X. pavonae n. sp. and X. taiwanensis n. sp. They were found together in a single washing of the host coral. Previously, 13 species of copepods have been found in association with nine species of Pavona Lamarck. More than half (7/13) of these symbionts are members of Xarifia Humes, 1960.  相似文献

Sativumoides punicae gen. et sp. nov. and Cladosporiopsis ovata gen. et sp. nov. are described and illustrated. Sativumoides is characterized by macronematous, individual, percurrently extending conidiophores, integrated, monoblastic, apical, lageniform conidiogenous cells, and single, apical, pale brown to brown, garlic-bulb-shaped dictyosporous conidia with predominantly longitudinal septa. Cladosporiopsis is unique in possessing pigmented, apiosporous conidia seceding schizolytically from integrated, monoblastic, determinate conidiogenous cells; the conidia, arising from the sides or ends of ramoconidia, form short, acropetal chains. Sativumoides is compared with similar anamorphic genera including Triposporium, Iyengarina, Acrodictys, Actinocladium, Piricaudiopsis, Cheiroidea, Stephanoma, Domingoella, Acrogenospora and Shrungabeeja. The distinctions between Cladosporiopsis and similar genera including Cladosporium, Ochrocladosporium, Rachicladosporium, Rhizacladosporium, Toxicocladosporium, Ramularia, Bispora, Lylea and Devriesia are also discussed. Keys to these two novel genera and their morphologically similar genera are provided.  相似文献

Invasive species trigger biodiversity losses and alter ecosystem functioning, with life history shaping invasiveness (Sakai et al., Annu Rev Ecol Syst 32:305–332, 2001). However, pinpointing the relation of a specific life history to invasion success is difficult. One approach may be comparing congeners. The two Palearctic pavement ants, Tetramorium sp.E (widely known as T. caespitum, Schlick-Steiner et al., Mol Phylogenet Evol 40:259–273, 2006) and T. tsushimae have invaded North America (Steiner et al., Biol Invasions 8:117–123, 2006). Their life histories differ in that T. sp.E has separate single-queened colonies but T. tsushimae multi-queened colonies scattered over large areas (Sanada-Morimura et al., Insect Soc 53:141–148, 2006; Schlick-Steiner et al., Mol Phylogenet Evol 40:259–273, 2006; Steiner et al., Biol Invasions 8:117–123, 2006). Comparison of the genetic diversity in the entire native and non-native ranges will elucidate the invasion histories. Here, we present 13 and 11 microsatellites, developed for T. sp.E and T. tsushimae, respectively, and characterize all for both species. Florian M. Steiner, Wolfgang Arthofer and Birgit C. Schlick-Steiner contributed equally to this work.  相似文献

Five species of Elasmus are described from Russia as new to science (E. altaicus sp. n., E. ekaterinae sp. n. and E. maritimus sp. n.), Turkmenistan (E. turkmenicus sp. n.), and Mongolia (E. emeljanovi sp. n.). E. nikolskayae Myartseva et Dzhanokmen, 1989 is redescribed. Elasmus obesoceratus Trjapitzin, 1979 is downgraded to a synonym to Elasmus rufiventris Ferrière, 1947. Sixteen species are recorded for the first time for the fauna of Russia, six for Tajikistan and Turkmenistan, five for Azerbaijan and Kazakhstan, four for Ukraine and Mongolia, two for Moldova, Georgia, Armenia, Uzbekistan, China, and South Korea, and also new single records are given for Poland, Slovakia, Abkhazia, Afghanistan, and Iran. New hosts are recorded for seven species: E. flabellatus Fonsocolombe, E. longiclava Graham, E. nudus (Nees), E. platyedrae Ferrière, E. schmitti Ruschka, E. steffani Viggiani, and E. westwoodi Giraud. A key to twenty-six species of Elasmus is compiled.  相似文献

In order to understand better non-target effect and potential uses, the host specificity of two parasitoid species (Anagyrus sp. nov. nr. sinope Noyes & Menezes and Leptomastix dactylopii Howard) (both Hymenoptera: Encyrtidae) for six mealybug species [Ferrisia virgata (Cockerell), Phenacoccus madeirensis Green, Phenacoccus solani Ferris, Planococcus citri (Risso),Pseudococcus longispinus (Targioni-Tozzetti) and Pseudococcus viburni (Signoret)] (all Hemiptera: Pseudococcidae) was studied through behavioral observations and laboratory rearing. The selected mealybug species represent major subfamilies and tribes of Pseudococcidae. Except for F. virgata, all mealybug species induced examinations by Anagyrus sp. nov. nr. sinope and L. dactylopii. Anagyrus sp. nov. nr. sinope was specific to P. madeirensis, which was the only mealybug species selected for oviposition and suitable for complete development of the parasitoid. No encapsulation of Anagyrus sp. nov. nr. sinope in P. madeirensis was observed. Leptomastix dactylopii accepted multiple species for oviposition, with the ranking of species preference as P. citri > P. viburni > P. longispinus > P. solani > P. madeirensis. Only P. citri, P. longispinus and P. viburni supported the development of L. dactylopii. Parasitoids developing in P. longispinus and P. viburni suffered from high encapsulation rates, while no encapsulation was observed when developing in P. citri. The results of this study suggest that Anagyrus sp. nov. nr. sinope is highly host specific. Leptomastix dactylopii, on the other hand, has a wider host range. The use of Anagyrus sp. nov. nr. sinope in a mealybug biological control program is limited to P. madeirensis and L. dactylopii to P. citri. The results presented in this study also lead us to question the accuracy of the reported host range of L. dactylopii, which include all six mealybug species tested.  相似文献

Polyhydroxyalkanoates (PHAs) are hydroxyalkanoate polymers that are produced and accumulate by many kinds of bacteria. These polymers act as an energy store for bacteria. Polyhydroxybutyrate (PHB) is the most studied polymer in the PHA family. These polymers have awakened interest in the environmental and industrial research areas because they are biodegradable and have thermoplastic qualities, like polypropylene. In this work, we analyzed the PHB production in Bradyrhizobium sp., Rhizobium leguminosarum bv. phaseoli, and Rhizobium huautlense cultured with two different carbon sources. We did biochemical quantification of PHB production during the three phases of growth. Moreover, these samples were used for RNA extraction and phbC gene expression analysis via real-time PCR. The bacteria showed different manner of growth, PHB accumulation and phbC gene expression when different quantity and quality of carbon sources were used. These results showed that under different growth media conditions, the growth and metabolism of different species of bacteria were influenced. These differences reflect the increase or decrease in PHB accumulation.  相似文献
