The genus Cvptostegia R. Br. comprises two species, both of which are endemic to Madagascar. One species, C. grandiflora Roxb. ex R. Br., is widely naturalised in tropical regions of the world. The other species, C. madagascariensis Bojer ex Decne., comprises three varieties, of which C. madagascariensis var. glaberrima (Hochreutiner) J. Marohasy & P. Forster is a new combination, and C. madagascariensis var. septentrionalis J. Marohasy & P. Forster is newly described. Interspecific hybrids occur in a narrow zone where the two species are sympatric.

A taxonomic revision of the Australian Conopidae is presented. Nineteen genera in four subfamilies are recognised. The Stylogasterinae are represented by the cosmopolitan genus Stylogaster Macquart and the Myopinae by Myopa Fabricius and Thecophora Rondani. A monotypic genus, Notoconops gen. nov., is described and placed in a new subfamily, Notoconopinae. The remaining fifteen Australian genera are assigned to the Conopinae. Australoconops Camras, Chrysidiomyia Kröber, Conops Linnaeus, Delkeskampomyia Kröber, Heteroconops Kröber, Microconops Kröber, Neoconops Kröber, Pleurocerina Macquart, Physocephala Schiner, Smartiomyia Kröber and Stenoconops Kröber are redescribed. Four new conopine genera are described: Atrichoparia; Camrasiconops; Setosiconops; and Tanyconops, with the following resultant new combinations: Atrichoparia curticornis (Kröber) (from Heteroconops); Camrasiconops ater (Camras) and Ca. rufofemoris (Camras) (from Microconops); and Setosiconops robustus (Kröber) (from Neoconops). Callosiconops Kröber and Paraconops Kröber are regarded as junior synonyms of Chrysidiomyia and Pleurocerina respectively with the following resultant new combinations: Chrysidiomyia hirsuta (Kröber), Pleurocerina aristalis (Camras), P. longicornis (Kröber), P. nigrifacies (Kröber), P. similis (Kröber), P. turneri (Camras). A total of 100 species of Australian Conopidae are now recognised. No new species of Myopinae or Stylogasterinae are described. Representative species only of Atrichoparia, Camrasiconops, Heteroconops and Microconops are described. All species of the other 12 genera are described or redescribed. These include the following 45 new species,: Australoconops aglaos, A. aurantius, A. balteus, A. breviplatus, A. brunneus, A. camrasi, A. cantrelli, A. elegans, A. fulvitarsus, A. furvus, A. nebrias, A. neuter, A. pallorivittus, A. phaeomeros, A. ruficrus, A. vespoides; Chrysidiomyia rugifrons, C. setosa; Conops aureolus, C. badius, C. chvalai, C. sparsus; Heteroconops carnarvonensis; Neoconops brevistylus, N. glaber; Notoconops alexanderi, Pleurocerina aquila, P. brevis, P. chrysopyga, P. lamellata, P. lutea,P. luteiceps, P. occidua, P. saxatilis, P. scutellata, P. vespiformis; Setosiconops epixanthus, Se. similis, Smartiomyia arena, Sm. cerina, Sm. danielsi, Sm. macalpinei; Tanyconops longicaudus, T. luteus, T. ocellatus. Australoconops ocellatus (de Meijere) comb. nov. is resurrected from synonymy with A. aurosus (Newman). Conops demeijerei Kröber is considered a junior synonym of C. seminiger de Meijere. A lectotype and paralectotypes are designated for Microconops fasciatus Kröber. Anatomical features used in descriptions are discussed and illustrated. Special attention has been given to the ultrastructure of spicules on female genital structures. These spicules show differences between genera and species. The high degree of endemism of the Australian fauna is discussed in relation to the world fauna and some preliminary thoughts on phylogenetic relationships are presented. A catalogue of the Australian Conopidae is included as an Appendix.

Dialium (Leguminosae, Dialiinae) is pantropical and comprises about 40 species. Presently, only one species occurs in the Neotropics, Dialium guianense, which is found from eastern Mexico to northeastern Minas Gerais, Brazil. The objective of this study was to carry out a thorough taxonomic revision of Dialium in the Neotropics, to determine if species diversity of the genus in this region is underestimated. The study analyzed 765 collections, from 18 herbaria throughout the world, which revealed three groups of specimens that clearly differ from each other and from D. guianense. Morphology and biogeography support their recognition as new species. Dialium hexaestaminatum occurs in northern Colombia and western Venezuela, and is characterized by generally having six stamens, while the other neotropical species have only two. Dialium congestum occurs in Ecuador and southern Colombia and is mainly characterized by the presence of congested inflorescences, unlike the lax inflorescences found in the other neotropical species.  Dialium rondoniense occurs in the state of Rondônia and the most southern part of the state of Amazonas, Brazil. It is characterized by the dense coverage of trichomes on the abaxial surface of the leaflets, as well as the petiolules, petioles, leaf rachis and branches, while the other neotropical species are generally glabrous or covered with sparse trichomes that are imperceptible to the bare eye. The results show that the diversity of Dialium in the Neotropics was underestimated and that the genus has four species in the region. An identification key, illustrations and descriptions of the species are provided.

Abstract. Recently, the monotypic ostracod genus Ankumia van Veen, 1932 was abandoned as nomen dubium by Jones (2003, p. 85) in favour of Platella Coryell & Fields, 1937 and a new combination was proposed for the type species of Ankumia, i.e. Platella bosqueti (van Veen, 1932). However, Ankumia bosqueti from the Maastrichtian of The Netherlands was introduced as an available taxon and, as documented by Jones (2003), the specific name is valid for recognizing the species in which ‘pathological individuals with retained moults’ occur. Therefore, there is no reason to treat Ankumia as nomen dubium. Yet, although there is no doubt about the cytherellid relationship of the species, two taxonomical questions still remain.(1) Do pathological individuals of cytherellids justify specific and/or generic ranking? Certainly they do not, and demonstration of a corresponding ‘normal’ species (including ‘pathological individuals’) among the associated cytherellids is wanting. On the other hand, if these pathological individuals can be proven as representing a discrete pathological genus, Ankumia remains as a valid genus to characterize the available species name bosqueti.(2) Why should Ankumia be abandoned in favour of Platella? When van den Bold (1967, pp. 306, 308) compared Coryell & Fields’ original Gatún ostracod fauna with his own collection from the Neogene Gatún Formation in the Panama Canal Zone, he recognized the type species, Platella gatunensis, as a small-sized cytherellid moult. Over the years about a dozen small- and normal-sized cytherellid species from all over the world have been assigned to Platella, ignoring the questionable taxonomic . . .

The Neotropical genus Marma Simon, 1902 is revised. With exception of the holotype of M. femella (Caporiacco, 1955), which was redescribed in previous work, all the other species of the genus were revised based on their types. The type species, M. baeri Simon, 1902, and M. nigritarsis (Simon, 1900) are redescribed based on newly collected specimens. The third and last species presently listed in the World Spider Catalog, M. femella, is confirmed as valid. Two species presently considered synonyms of M. nigritarsis are revalidated: M. rosea (Mello-Leitão, 1941) and M. argentina (Mello-Leitão, 1941). Two species are synonymized: Thysema dorae Mello-Leitão, 1944, syn. nov. with Ocnotelus argentinus Mello-Leitão, 1941 and Paralophostica centralis Soares & Camargo, 1948, syn. nov. with Agelista rosea Mello-Leitão, 1941. Pseudoamphidraus variegatus Caporiacco, 1947 and M. trifidocarinata Caporiacco, 1947 are confirmed as synonyms of M. nigritarsis. Six new species from northern/northeastern Brazil are described: M. abaira sp. nov. (♀), M. linae sp. nov. (♂♀), M. pipa sp. nov. (♂♀), M. sinuosa sp. nov. (♂♀), M. spelunca sp. nov. (♂♀) and M. wesolowskae sp. nov. (♂♀). Also, the male of M. argentina is described for the first time. We give new diagnostic illustrations and updated distribution records for all the species of the genus.

Phylogenetic relationships of the World genera of dobsonflies, subfamily Corydalinae, are reappraised, as well as those of species of the New World genus Corydalus, both on the basis of morphological characters. Previous phylogenetic hypotheses of dobsonfly genera by Glorioso, Penny, and Contreras-Ramos, respectively, are re-evaluated, and a fourth revised phylogeny is presented. Ninety-five characters of 10 taxa, one outgroup and nine ingroup taxa, were used in the updated analysis of Corydalinae. It recognizes four lineages, with Chloroniella as sister to the other three, of which the Nevromus lineage (Acanthacorydalis + Nevromus + Neoneuromus) is sister to the Corydalus lineage (Chloronia + Platyneuromus + Corydalus), and both as a group are sister to the Protohermes lineage (Protohermes + Neurhermes). The main changes in the updated Corydalinae phylogeny are the placement of Chloroniella as sister to all other dobsonfly genera, and the placement of Acanthacorydalis as a member of the Nevromus lineage. Previously, Penny had proposed Chloroniella as sister to all dobsonfly genera except the Protohermes lineage, and both Glorioso and Penny, respectively, placed Acanthacorydalis as sister to the Corydalus lineage. About Corydalus, its species phylogeny is herein updated, as four species from Venezuela were added to the genus after its taxonomic revision. For the new phylogeny, 120 characters of 35 taxa, two outgroup and 33 ingroup taxa, were used. It produced a strict consensus of two trees, better resolved than the previous one. The C. arpi species group is moved to sister of all other species except the C. cephalotes species pair, while the C. batesii species group is conserved, being the only unresolved group within the phylogeny. Two of the species added, C. hayashii and C. mayri, belong to the well defined C. arpi species group, of Guayana Shield affinity, whereas C. crossi is sister to a large and widespread group beginning with the C. nubilus species group, and C. clavijoi is sister to C. tesselatus within the latter group.

Russian economy has reached the low level of inflation, but economic growth has not accelerated. Moreover, according to official forecasts, in the following years it will still be low. The article concludes that domestic demand, which is one of the main factors of growth, is significantly constrained by monetary, budgetary and fiscal spheres. The situation in the Russian economy is still hampered by the decline of the world economic growth. The prospects of financial markets are highly uncertain. This increases the possibility of crisis in the world. Leading countries widely use non-traditional measures to support their economies in the similar environment. In the world economy as well as in Russia a principally new combination of factors has emerged, which create specific features of economic growth. It requires special set of measures to stimulate such growth. The article proves that Russian regulators have large unused potential to stimulate growth. It includes monetization, long-money creation, budget and tax stimuli. It is important that the instruments, which will be used, should be based on domestic mechanisms. This will strengthen financial basis of the economy and may encourage economic growth. Some specific suggestions as to their use are made.

There are two most inevitable issues on national literature, in this case Indonesian literature. First is the translation and the second is the standard of world literature. Can one speak for the other as a representative? Why is this representation matter? Does translation embody the voice of the represented? Without translation Indonesian literature cannot gain its recognition in world literature, yet, translation conveys the voice of other. In the case of production, publication, or distribution of Indonesian Literature to the world, translation works can be very beneficial. The position of Indonesian literature is as a part of world literature. The concept that the Western world should be the one who represent the subaltern can be overcome as long as the subaltern performs as the active speaker. If the subaltern remains silent then it means it allows the “representation” by the Western.

The main objective of this study is the substantiation of experiment as one of the key features of the world music in Ukraine. Based on the creative works of the brightest world music representatives in Ukraine, «Dakha Brakha» band, the experiment is regarded as a kind of creative setting. Methodology and scientific approaches. The methodology was based on the music practice theory by T. Cherednychenko. The author distinguishes four binary oppositions, which can describe the musical practice. According to one of these oppositions («observance of the canon or violation of the canon»), the musical practices, to which the Ukrainian musicology usually classifies the world music («folk music» and «minstrel music»), are compared with the creative work of «Dakha Brakha» band. Study findings. A lack of the setting to experiment in the musical practices of the «folk music» and «minstrel music» separates the world music musical practice from them. Therefore, the world music is a separate type of musical practice in which the experiment is crucial. The study analyzed several scientific articles of Ukrainian musicologists on the world music; examined the history of the Ukrainian «Dakha Brakha» band; presented a list of the folk songs used in the fifth album «The Road» by «Dakha Brakha» band; and showed the degree of the source transformation by musicians based on the example of the «Monk» song. The study findings can be used to form a comprehensive understanding of the world music musical practice. The further studies may be related to clarification of the other parameters of the world music musical practice, and to determination of the experiment role in creative works of the other world music representatives, both Ukrainian and foreign. The practical study value is the ability to use its key provisions in the course of modern music in higher artistic schools of Ukraine. Originality / value. So far, the Ukrainian musicology did not consider the experiment role as the key one in the world music.

The paper celebrates the publication of Ranjan Ghosh and J. Hillis Miller's Thinking Literature across Continents as a significant event in the age of neoliberalism. It argues that, in spite of the different premises and the resulting interpretative procedures respectively championed by the two co-authors, both of them anchor their readings of literary texts in a concept of literature that is diametrically opposed to neoliberal rationality, and both impassionedly safeguard human values and experiences that resist the technologisation and marketisation of the humanities and aesthetic education. While Ghosh's readings of literature offer lightning flashes of thought from the outside of the Western tradition, signalling a new culture of reading as well as a new manner of appreciation of the other, Miller dedicatedly speaks and thinks against the hegemony of neoliberal reason, opening our eyes to the kind of change our teaching or reading of literature can trigger in the world, and the role aesthetic education should and can play at a time when the humanities are considered ‘a lost cause’.

Most studies of Simone de Beauvoir situate her with respect to Hegel and the tradition of 20th-century phenomenology begun by Husserl, Heidegger, and Merleau-Ponty. This book analyzes The Second Sex in light of the concepts of becoming, problematization, and the Other found in Gilles Deleuze. Reading Beauvoir through a Deleuzian lens allows more emphasis to be placed on Beauvoir's early interest in Bergson and Leibniz, and on the individuation of consciousness, a puzzle of continuing interest to both phenomenologists and Deleuzians. By engaging with the philosophical issues in her novels and student diaries, this book rethinks Beauvoir’s focus on recognition in The Second Sex in terms of women’s struggle to individuate themselves despite sexist forms of representation. It shows how specific forms of women’s “lived experience” can be understood as the result of habits conforming to and resisting this sexist “sense.” Later feminists put forward important criticisms regarding Beauvoir’s claims not to be a philosopher, as well as the value of sexual difference and the supposedly Eurocentric universalism of her thought. Deleuzians, on the other hand, might well object to her ideas about recognition. This book attempts to address those criticisms, while challenging the historicist assumptions behind many efforts to establish Beauvoir’s significance as a philosopher and feminist thinker. As a result, readers can establish a productive relationship between Beauvoir’s “problems” and those of women around the world who read her work under very different circumstances.
