The pyrgine genus Porphyrogenes Watson, 1893 (Hesperiidae) is discussed, especially as it occurs in central Rondônia, Brazil. Of eleven species of Porphyrogenes found in Rondônia, four (P. specularis, P. convexus, P. sparus, and P. spadix) are described as new species. Biological details of the genus are discussed. An additional five new species of Porphyrogenes (P. spina, P. sporta, P. splendidus, P. simulator, and P. speciosus) are described from elsewhere. Porphyrogenes cervinus (Plötz, 1883), new synonym of Porphyrogenes ferruginea (Plötz, 1883), reinstated status, is raised from a subspecies of Porphyrogenes despecta (Butler, 1870) to species-level. Porphyrogenes omphale (Butler, 1871), reinstated status, is not synonymous with Porphyrogenes passalus (Herrich-Schäffer, 1869) and becomes a species-level taxon for which no subspecies are recognized; P. passalus was described from a female with no known male. Porphyrogenes sula Williams and Bell, 1940, reinstated status, is raised from synonymy with Porphyrogenes zohra (Möschler, 1879) to species-level. Porphyrogenes stresa Evans, 1952, new status, is raised from a subspecies of P. zohra to species-level. Porphyrogenes immaculata (Skinner, 1920), new synonymy, was described from a male, which we believe is the male of Porphyrogenes sororcula (Mabille and Boullet, 1912). Porphyrogenes suva Evans, 1952, new synonymy, formerly considered a full species, was described from a male which we believe is the male of, and thus synonymous with, Porphyrogenes probus (Möschler, 1877). Porphyrogenes virgatus (Mabille, 1888) and Porphyrogenes eudemus (Mabille, 1888), considered synonyms of P. zohra and Porphyrogenes vulpecula (Plötz, 1882), respectively, without justification by Evans (1952), are removed from those synonymies and retained, along with P. passalus, as females without confirmed affinities. Lectotypes are here designated for Phareas ferruginea Plötz, 1883; Augiades despecta Butler, 1870; Telegonus omphale Butler, 1871; Eudamus pausias Hewitson, 1867; Telegonus probus Möschler, 1877; Telemiades vulpecula Plötz, 1882; Eudamus passalus Herrich-Schäffer, 1869; Thymele virgatus Mabille, 1888; and Thymele eudemus Mabille, 1888. A neotype is designated for Phareas cervinus Plötz, 1883, that being the lectotype of Phareas ferruginea. Types of all taxa in the genus are illustrated. Three named and five unnamed phenotypes of females, not reconciled with males, are identified and described. Twenty-six species are now recognized, making this one of the largest hesperiid genera in the neotropics.
Thirteen species of skippers (six newly described; Lepidoptera: Hesperiidae: Hesperiinae: Hesperiini) from higher elevations of Mexico and Central America are reviewed. These are included in four genera (one newly described), some with proposed new combinations. Onespa Steinhauser, 1974, originally described as monotypic, is shown to include three species in addition to its type species, Onespa nubis Steinhauser, 1974. One of these, Atrytone gala Godman, 1900, that has been misplaced in several genera since its description, represents a new combination. The other two species, distributed in montane habitats in northwestern Mexico and in Costa Rica, are described as new. Buzyges Godman, 1900, distributed in Mexico and Central America and also formerly considered monotypic, is shown to embrace four species. Besides the type species, Buzyges idothea Godman, 1900, two species long placed in Poanes Scudder, 1872, Pamphila rolla Mabille, 1883, and Poanes benito Freeman, 1979, are included as new combinations. Another species, known only from Costa Rica, is described as new. These are united by several superficial characters, but especially by genital morphology of both sexes. Librita Evans, 1955, was described to include three species of which one, Librita raspa Evans, 1955, was subsequently removed. Augiades heras Godman, 1900 is here also removed from Librita and placed in a new genus with three previously undescribed species. This completes the disintegration of Librita, which is now monotypic. The four genera, although exhibiting similarities suggesting potential alliance, differ in their unique combinations of several superficial and genital traits from each other and other hesperiine skippers.
Acht Pistolenkugeln werden aus nächster Nähe abgefeuert, aber keine trifft ihr Ziel. Denn der Superheld Quicksilver kann sich im Film "X-Men: Days Of Future Past" (2014) mit einer Geschwindigkeit bewegen, die es ihm erlaubt, die Flugbahn der Kugeln mit kleinen kinetischen Impulsen zu manipulieren. Antizipiert wurde diese Figur der legendären Marvel-Autoren Stan Lee und Jack Kirby bereits im Jahr 1860, als der Naturforscher Karl Ernst von Baer ein Gedankenexperiment anstellte. Baer spekulierte darüber, wie sich die Welt für einen Menschen darstellt, der zwar ebenso viele Sinneseindrücke pro Pulsschlag hat wie ein normaler Mensch, dessen Puls aber 1.000 Mal schneller schlägt. Ein solcher Mensch würde einer vorbeifliegenden Kugel sehr leicht folgen können, schreibt Baer, hätte allerdings aufgrund seines anderen Metabolismus auch eine deutlich geringere Lebensdauer von nur einem Monat.
Während man in Deutschland die Debatte um eine mögliche 'Rephilologisierung' der Literaturwissenschaft abermals zu entzünden sucht, ist in den USA der ebenfalls seit Ende der 1990er Jahre geführte Methodenstreit um die 'neuen Formalismen' in der Literaturtheorie bereits neuerlich entbrannt. Hier wie dort steht (nochmalig) zur Diskussion, wie Literatur als wissenschaftlicher Gegenstand konstituiert werden solle, was das 'Kerngeschäft' der Literaturwissenschaft sei und wie sie sich zu anderen Disziplinen ins Verhältnis zu setzen habe. Zwar sind die Zeiten vorbei, in denen sich eine immanent operierende, auf formale Aspekte fokussierte Lektürepraxis und eine historisch-kontextualisierende Herangehensweise so antagonistisch gegenüberstehen wie etwa im Fall von New Criticism und New Historicism. Gleichwohl bleibt der Stellenwert von Formfragen ein gewichtiges, vielleicht entscheidendes Moment der Debatten. Von Belang ist die aktuelle Diskussion in den USA zum einen, weil die neuen formalistischen Ansätze eben nicht mehr nur unter Ausschließung historischer oder kulturwissenschaftlicher Problemstellungen verfahren; zum anderen, weil dort eine (wissenschafts‑)politische Dimension dieser Fragen ins Licht rückt. In den folgenden Beiträgen, die im Anschluss an den ZfL-Workshop "Die 'neuen Formalismen' - Form, Geschichte, Gesellschaft" entstanden sind, diskutieren Eva Axer, Werner Michler und Marjorie Levinson die Konjunktur des Formbegriffs und der 'neuen Formalismen'.
A new jumping spider genus, Manzuma gen. nov. (Salticidae Blackwall, 1841), is described, type species is Manzuma nigritibia (Caporiacco, 1941). Aelurillus reconditus Wesołowska & van Harten, 1994 is synonymized with Rafalus nigritibiis (Caporiacco, 1941). Four new combinations are proposed: M. jocquei gen. et comb. nov. (ex Aelurillus), M. kenyaensis gen. et comb. nov. (ex Langelurillus), M. lympha gen. et comb. nov. (ex Rafalus) and M. nigritibia gen. et comb. nov. (ex Rafalus). Three species, M. botswana gen. et sp. nov. (♂♀, Botswana and Republic of South Africa), M. petroae gen. et sp. nov. (♂♀, Republic of South Africa) and M. tanzanica gen. et sp. nov. (♂, Tanzania), are described. The male of M. kenyaensis gen. et comb. nov. and female of M. lympha gen. et comb. nov. are described for the first time. A new aelurilline synapomorphy is proposed. Identification key for males is provided.
We describe a new vanilla species growing in sympatry with Vanilla planifolia Jacks. ex Andrews (Orchidaceae) in the province of Limón, Caribbean coast of Costa Rica. The morphology of the reproductive and vegetative organs observed on vines cultivated under shade-house, the nuclear (Internal Transcribed Spacer) and plastid (matK) nucleotide sequences, as well as the contents of aromatic compounds measured in ripe fruits, show that this species is close to but distinct from V. planifolia. The name V. sotoarenasii M.Pignal, Azofeifa-Bolaños & Grisoni sp. nov. is proposed for this new Vanilla species endemic in Costa Rica. It is especially distinguished from V. planifolia by a reduction of about 30% of the size of the fruits and flowers, by a divergence of ITS sequences for at least two species-conserved nucleotides compared to seven other species of the V. planifolia group, and by the presence of anisic compounds and low content of phenolic compounds (including vanillin) in the fruits. These results confirmed the extension of the area of distribution of V. planifolia southward to Costa Rica, where a recent speciation process occurred. Because of its particular agronomic and aromatic properties, V. sotoarenasii sp. nov. could represent a valuable biological resource for the vanilla industry.
