    Moth Species New to Michigan

    Get PDF
    This is a compilation of moth species previously unrecorded from Michigan. Moore\u27s (1955) publication has been critically examined necessitating some specific changes. All questionable material has been determined by present day specialists in their particular fields. The McDunnough (1938) checklist is followed in the arrangement of the new data together with most of the recent changes in nomenclature as presented by Forbes (1948, 1954, 1960), Hardwick (1970), Hodges (1971), and Covell (1970, 1971). With the advent of more sophisticated collecting equipment and the easier access to Michigan\u27s Upper Peninsula a total of 154 species has been added. Many institutional and private collections have been examined including the large collection at Michigan State University which was not considered in the Moore publication

    In this study, four species of Entolomataceae family, were studied namely Entoloma papillatum, Entoloma rhodopolium, Nolanea hirtipes and N. cucullata are harvested for the first time in Morocco. The genus Entoloma' species were encountered in Quercus suber in the forest of Mamora (Northwestern Morocco) and those of the Nolanea' genus under Quercus rotundifolia in the forest El Harcha (Northeast of the Central Plateau)

    Description and analysis of a new Species of mineral, petterdite, A new oxychloride of lead

    Get PDF
    This apparently absolutely new chemical combination occurs in attached crystal groups in a quartz gangue containing disseminated pyrites, in the form of somewhat thin hexagonal plates, which are usually minute in size (about 5 millemetres in diameter), but occasionally reach 9 mm. dia., and, still more rarely, a larger size. Macles are not rare, irregularly attached and implanted on each other, and on the matrix

    A review of the genus Dysmerus Casey (Coleoptera: Laemophloeidae)

    Get PDF
    The New World genus Dysmerus Casey, currently with one valid species, is revised. Lectotypes are designated for two species, Dysmerus caseyi (Grouvelle), new status, and Dysmerus sulcicollis Grouvelle, new status. Both are revived from synonymy with D. basalis Casey. Twelve new species are described: Dysmerus boliviensis Thomas, new species, Dysmerus curvicornis Thomas, new species, Dysmerus genaspinosus Thomas, new species, Dysmerus hamaticornis Thomas, new species, Dysmerus impolitus Thomas, new species, Dysmerus skelleyi Thomas, new species, Dysmerus mexicanus Thomas, new species, Dysmerus monstrosus Thomas, new species, Dysmerus politus Thomas, new species, Dysmerus rondoniensis Thomas, new species, Dysmerus symphilus Thomas, new species, and Dysmerus trinidadensis Thomas, new species. A key to adults of the species and illustrations are provided

    A new species of Siparuna (Siparunaceae), S. ficoides, is described, illustrated, and placed in a phylogenetic context based on morphological and DNA sequence data. The species, which is a monoecious subcanopy tree, is known from three collections made near Manaus, Brazil (two from the same tree), and one in the state of Bolivar, Venezuela.Se describe y se ilustra una nueva especie de Siparuna (Siparunaceae), S. ficoides, ademas se la ubica en un contexto filogenetico basado en datos morfologicos y en sequencias de DNA. Esta nueva especie es un arbol monoico de subdosel, de la cual se han registrado tres colecciones cerca de Manaos, Brasil (dos del mismo arbol) y una coleccion en el Estadod e Bolivar, Venezuela

    Theclinae of Rondonia, Brazil: Strymon Hübner : with descriptions of new species (Lepidoptera: Lycaenidae)

    Get PDF
    Twenty-two species of Strymon are known from the vicinity of Cacaulandia in Rondonia, Brazil, of which 14 are new species. These belong to 5 species groups: the "oreala" group [Strymon megarus (Godart)]; the "ziba" group [Strymon ziba (Hewitson), Strymon thulia (Hewitson), Strymon spinatus new species, Strymon latamaculus new species, Strymon pallidulus new species, Stlymon tholus new species]; "valentina" group [Strymon rotundum new species]; "crossoea" group [Strymon crossoea (Hewitson), Strymon crambusa (Hewitson), Stlymon germana new species, Strymon novasignum new species, Strymon clavus new species, Strymon implexus new species, Strymon inmirum new species, Strymon incanus new species, Strymon faunalia (Hewitson), Strymon halos new species, Strymon conspergus new species, Strymon bazochii (Godart), Strymon diagonalis new species]; and "eurytulus" group [Strymon bubastus (Stoll)]. Tentative subgroups of species are suggested for the "crossoea" group as they occur in Rondonia. A neotype is designated for Tmolus basilides and the name synonymized with Strymon megarus. The "basilides" group of Johnson et al. (1990) is renamed the "ziba" group. Based on lectotype designations and superficial and genital differences, S. ziba and S. thu.lia are elevated to specific status

    New Species of Siparuna (Siparunaceae) III

    Get PDF
    Three new species of Siparuna (Siparunaceae) are described, illustrated, and placed in a phylogenetic context: S. gentryana from western Ecuador and adjacent Colombia, S. lozaniana from the western Andes in Colombia, and S. vasqueziana from Amazonian Peru. In addition, Siparuna calantha from the Sierra Nevada de Santa Marta, originally described by Janet Perkins as a variety of a Mexican entity, is raised to species rank because its broader leaves and more numerous carpels readily distinguish it from its apparent closest relative, a species from the western Colombian Andes. Each of the species is known from several collections, which allowed the secure matching of sexual morphs in the three that are dioecious

    New Light Species and the CMB

    Full text link
    We consider the effects of new light species on the Cosmic Microwave Background. In the massless limit, these effects can be parameterized in terms of a single number, the relativistic degrees of freedom. We perform a thorough survey of natural, minimal models containing new light species and numerically calculate the precise contribution of each of these models to this number in the framework of effective field theory. After reviewing the relevant details of early universe thermodynamics, we provide a map between the parameters of any particular theory and the predicted effective number of degrees of freedom. We then use this map to interpret the recent results from the Cosmic Microwave Background survey done by the Planck satellite. Using this data, we present new constraints on the parameter space of several models containing new light species. Future measurements of the Cosmic Microwave Background can be used with this map to further constrain the parameter space of all such models.Comment: 38 pages plus appendices and references; 10 figures and 1 table; references added, discussion of anapole moments added; supernovae cooling bounds added, discussion of models condense
