Aphanius vladykovi,a new species of tooth-carp from the Zagros Mountains of Iran (Osteichthyes: Cyprinodontidae)

Synopsis A new species of tooth-carp, Aphanius vladykovi, is described from the Zagros Mountains of Iran. The new species is uniquely characterised by a high count of lateral line scales and by different pigmentation patterns from its closest, putative relative A. sophiae. It also possesses several meristic and morphometric differences with topotypic A. sophiae. It became separated from a common ancestor with A. sophiae by orogenic events which led to the formation of the Zagros Mountains and the isolation of the upper reaches of the Karun River basin by the development of tangs, narrow passes through the mountains with high water flow and steep gradient which prevent gene flow between lowland and mountain populations of these small fishes.     

Two halophilic Ectothiorhodospira strains with unusual morphological,physiological and biochemical characters

Two strains belonging to the genus Ectothiorhodospira were isolated from enrichment cultures inoculated with sulfide-containing samples from the saltern of Trapani. Cells are motile short spirilla with internal stacks of membranes. During sulfide utilization they produce external globules of sulfur that are then completely oxidized to sulfate. These halophilic microorganisms need NaCl concentrations of 11% and 18% and a slightly alkaline pH. They are typical photoautotrophic bacteria, utilizing sulfide, sulfur and, only one of them, thiosulfate as photosynthetic electron donors; growth is stimulated by organic compounds. Neither of the two strains is capable of assimilatory sulfate reduction and neither grows in the dark. Pigments of the two strains are bacteriochlorophyll a and carotenoids of the normal spirilloxanthin series subgroup 1B. Quinones are Q8 and MK8 in a strain and Q8 and MK7 in the other one: the latter situation, with quinone side chains of different lengths, is atypical within phototrophic bacteria. For morphological, physiological and biochemical characters, at least one of these strains clearly stays apart from the six Ectothiorhodospira species described until now.List of abbreviations HPLC high performance liquid chromatography - TLC thin layer chromatography - Qn ubiquinone—number of isoprenoid units of the side chain - MKn menaquinone—number of isoprenoid units of the side chain - R_t retention time - R_f retention factor Dedicated to the memory of Professor Gino Florenzano who inspired this work     

Taxonomic studies on some human cutaneous coryneform bacteria: Description of Dermabacter hominis gen.nov., sp.nov.

Abstract Taxonomic studies were performed on some Gram-positive asporogeneous rod-shaped bacteria isolated from human skin. On the basis of biochemical and chemical characteristics the cutaneous strains differ from all taxa described to date. It is proposed that these organisms be classified in a new genus Dermabacter , as Dermabacter hominis gen.nov., sp.nov.     

A new species of the genus Anteon Jurine (Hymenoptera,Dryinidae) from Laos

A new species of Anteon Jurine, 1807 is described from Laos, Houaphanh Province: Anteon holzschuhi sp. n. Morphologically the new species is similar to Anteon semipolitum Olmi, 2008, but it is distinguished by the sculpture of the face partly reticulate rugose and partly with deep punctures similar to areolae; in Anteon semipolitum the face is completely punctate and unsculptured among punctures. In addition, in the new species the distance from the outer edge of a lateral ocellus to the compound eye (OOL) is about 3.3 times as long as the distance between the inner edges of a lateral ocellus and the median ocellus (OL); in Anteon semipolitum OOL is less than twice as long as OL. Published identification keys to the Oriental species of Anteon are modified to include the new species.     

Towards a Global Names Architecture: The future of indexing scientific names

For more than 250 years, the taxonomic enterprise has remained almost unchanged. Certainly, the tools of the trade have improved: months-long journeys aboard sailing ships have been reduced to hours aboard jet airplanes; advanced technology allows humans to access environments that were once utterly inaccessible; GPS has replaced crude maps; digital hi-resolution imagery provides far more accurate renderings of organisms that even the best commissioned artists of a century ago; and primitive candle-lit microscopes have been replaced by an array of technologies ranging from scanning electron microscopy to DNA sequencing. But the basic paradigm remains the same. Perhaps the most revolutionary change of all – which we are still in the midst of, and which has not yet been fully realized – is the means by which taxonomists manage and communicate the information of their trade. The rapid evolution in recent decades of computer database management software, and of information dissemination via the Internet, have both dramatically improved the potential for streamlining the entire taxonomic process. Unfortunately, the potential still largely exceeds the reality. The vast majority of taxonomic information is either not yet digitized, or digitized in a form that does not allow direct and easy access. Moreover, the information that is easily accessed in digital form is not yet seamlessly interconnected. In an effort to bring reality closer to potential, a loose affiliation of major taxonomic resources, including GBIF, the Encyclopedia of Life, NBII, Catalog of Life, ITIS, IPNI, ICZN, Index Fungorum, and many others have been crafting a “Global Names Architecture” (GNA). The intention of the GNA is not to replace any of the existing taxonomic data initiatives, but rather to serve as a dynamic index to interconnect them in a way that streamlines the entire taxonomic enterprise: from gathering specimens in the field, to publication of new taxa and related data.     

Venturia chinensis sp. nov., a new venturialean ascomycete from Khingan Mountains

A new species of Venturia (V. chinensis) is described and illustrated from the leaves of Lonicera praeflorens collected from Lesser Khingan Mountains, the northeast China. It is characterized by habitat saprobic; ascomata small-sized, solitary or scattered, superficial, subglobose to citriform, wall black, papillate, ostiolate, covered with setae; peridium thin; hamathecium evanescent in mature ascomata; asci 8-spored, bitunicate, fissitunicate, oblong to obclavate, with or without a short, knob-like pedicel; ascospores ellipsoidal, olivaceous pale brown, 1-septate, ascospore wall thin, smooth. Comparisons of V. chinensis with V. lonicerae (another species on Lonicera caerulea) and other species of Venturia lead to the conclusion that collected taxon is new. Its relationships with other species of Venturia are discussed based on morphology and 28S nrDNA and ITS nrDNA sequence comparisons.     

A new genus and species (Cornucollis gen. n. masoalensis sp. n.) of praying mantis from northern Madagascar (Mantodea,Iridopterygidae, Tropidomantinae)

An examination of Malagasy specimens accessed within the Muséum national d’Histoire naturelle, Paris, France, produced a praying mantis (Insecta: Mantodea) of an undescribed genus and species. An investigation of the internal and external morphology, in addition to its collection locality, revealed that this specimen belongs to the Iridopterygidae subfamily Tropidomantinae. Furthermore, the specimen’s unique combination of characters justified the creation of a new genus. Geographic distributional records and external morphological character evidence are presented for Cornucollis gen. n. masoalensis sp. n. We provide a dichotomous key of the Tropidomantinae and Nilomantinae genera distributed within Madagascar. High-resolution images, illustrations of morphological characters, natural history information, and measurement data are presented.     

The Late Miocene species Ochotona kalfense (Mammalia,Lagomorpha) of Moldova: The oldest European record of the genus in the context of the earliest Ochotoninae

Although the pika from the Moldovan Kalfa locality (early MN10) — representing the oldest European record of Ochotoninae (the clade derived from Bellatona) — is of crucial importance to understand the earliest history of Ochotona, its taxonomy has remained unclear until now. The paper fills the gap by providing a detailed revision of the type material from Kalfa, originally referred to Proochotona kalfense. The analysis is supported by a direct comparison with type materials of Proochotona eximia, Bellatonoides eroli, and Ochotona ozansoyi, the important early ochotonines of the peri-Paratethyan area. The genus Proochotona is regarded here as a junior subjective synonym of Ochotona. The specie kalfense is confirmed to be valid, undoubtedly belonging to the genus Ochotona. It demonstrates an occurrence of a surprisingly advanced p3 phenotype already present in the pre-Turolian of Europe. At the Holoarctic scale, a detailed synoptic survey and discussion of the fossil record, taxonomy, and phylogeny of the oldest representatives of Ochotoninae are provided.
