Sistemática, filogenia e distribuição geográfica das espécies sul-americanas de Centris (Paracentris) Cameron, 1903 e de Centris (Penthemisia) Moure, 1950, incluindo uma análise filogenética do "grupo Centris" sensu Ayala, 1998 (Hymenoptera, Apoidea, Centridini)

Systematics, phylogeny and geographical distribution of the South American species of Centris (Paracentris) Cameron, 1903, and Centris (Penthemisia) Moure, 1950, including a phylogenetic analysis of the "Centris group" sensu Ayala, 1998 (Hymenoptera, Apoidea, Centridini). A cladistic analysis with the objective of testing the hypothesis of monophily of Centris (Paracentris) Cameron, 1903, and of studying its phylogenetic relationships with the other subgenera that belong to the Centris group, sensu Ayala, 1998, and the relationships among the species that occur in South America, is presented. Centris (Paracentris) is a group of New World bees of amphitropical distribution, especially diversified in the Andes and in the xeric areas of South and North America. Thirty-one species were included in the analysis, four considered as outgroup, and 49 characters, all from external morphology and genitalia of adult specimens. Parsimony analyses with equal weights for the characters and successive weighting were performed with the programs NONA and PAUP, and analyses of implied weighting with the program PeeWee. The strict consensus among the trees obtained in all the analyses indicates that C. (Paracentris), as previously recognized, is a paraphyletic group. In order to eliminate that condition, the subgenera C. (Acritocentris), C. (Exallocentris) and C. (Xerocentris), all described by SNELLING (1974) are synonymized under C. (Paracentris). The subgenus C. (Penthemisia) Moure, 1950, previously considered a synonym of C. (Paracentris), is reinstated, but in a more restricted sense than originally proposed and with the following species: Centris brethesi Schrottky, 1902; C. buchholzi Herbst, 1918; C. chilensis (Spinola, 1851), C. mixta mixta Friese, 1904, and C. mixta tamarugalis Toro & Chiappa, 1989. Centris mixta, previously recognized as the only South American species of the subgenus C. (Xerocentris), a group supposedly amphitropical, came out as the sister-species of C. buchholzi. The following South American species were recognized under Centris (Paracentris): Centris burgdorfi Friese, 1901; C. caelebs Friese, 1900; C. cordillerana Roig-Alsina, 2000; C. euphenax Cockerell, 1913; C. flavohirta Friese, 1900; C. garleppi (Schrottky, 1913); C. klugii Friese, 1900; C. lyngbyei Jensen-Haarup, 1908; C. mourei Roig-Alsina, 2000; C. neffi Moure, 2000; C. nigerrima (Spinola, 1851); C. toroi sp. nov.; C. tricolor Friese, 1900; C. unifasciata (Schrottky, 1913), and C. vogeli Roig-Alsina, 2000. The relationships among the subgenera of the "Centris group" were: (Xanthemisia (Penthemisia (Centris s. str. - Paracentris))). Centris xanthomelaena Moure & Castro 2001, an endemic species of the Caatinga and previously considered a C. (Paracentris), came out as the sister group of C. (Centris) s. str. A new species of C. (Paracentris) from Chile is described: Centris toroi sp. nov. Lectotypus designations and redescriptions are presented for Centris burgdorfi, C. caelebs, C. lyngbyei, C. tricolor, C. autrani Vachal, 1904 and C. smithii Friese, 1900. New synonyms proposed: C. buchholzi Herbst, 1918 = Centris wilmattae Cockerell, 1926 syn. nov.; C. caelebs Friese, 1900 = Paracentris fulvohirta Cameron, 1903. The female of C. vogeli Roig-Alsina, 2000 and the male of C. xanthomelaena are described.

Revision of the Neotropical Xanthandrus Verral (Diptera, Syrphidae)

The Neotropical genus Xanthandrus Verral, 1901 is revised. Six species are redescribed: X. bucephalus (Wiedemann, 1830), X. cubanus Fluke, 1936, X. mellinoides (Macquart, 1846), X. mexicanus Curran, 1930, X. nitidulus Fluke, 1937, and X. plaumanni Fluke, 1937. Three species are included based on original descriptions: X. flavomaculatus Shannon, 1927, X. palliatus (Fluke, 1945), and X. simplex (Loew, 1861). New synonyms proposed: Argentinomyia longicornis (Walker, 1837) = Xanthandrus biguttatus Hull, 1945 syn. nov., and Xanthandrus bucephalus (Wiedemann, 1830) = Melanostoma quadrinotata Bigot, 1884 syn. nov. Description of terminalia, a key for Neotropical species, and illustrations are also presented.

Taxonomy, species richness and biogeography of Finnish crane flies (Diptera, Tipuloidea).

Biodiversity is unequally spread throughout terrestrial ecosystems. The highest species richness of animals and plants is encountered around the Equator, and naturalists observe a decrease in the number of creatures with increasing latitude. Some animal groups, however, display an anomalous species richness pattern, but these are exceptions to the general rule. Crane flies (Diptera, Tipuloidea) are small to large sized, non-biting nematoceran insects, being mainly associated with moist environments. The species richness of crane flies is highest in the tropics, but these insects are species rich and abundant in all biogeographic realms, boreal and arctic biomes included. The phylogeny and systematics of crane flies are still at an early stage and somewhat controversial. New species are constantly discovered even from temperate Europe, faunistically the best known continent. Crane flies have been rather neglected group of insects in Finland. The history of Finnish crane fly taxonomy and faunistics started in 1907, the year when Carl Lundström published his two first articles on tipuloids. Within roughly 100 years there have been only a handful of entomologists studying the Finnish fauna, and the species richness and natural history of these flies have remained poorly understood and mapped. The aim of this thesis is to clarify the taxonomy of Finnish crane flies, present an updated and annotated list of species and seek patterns in regional species richness and assemblage composition. Tipula stackelbergi Alexander has been revised (I). This species was elevated to a species rank from a subspecific rank under T. pruinosa Wiedemann and T. stackelbergi was also deleted from the list of European crane flies. Two new synonyms were found: T. subpruinosa Mannheims is a junior synonym of T. freyana Lackschewitz and T. usuriensis Alexander is a junior synonym of T. pruinosa. A new species Tipula recondita Pilipenko & Salmela has been described (II). Both morphology and COI (mtDNA) sequences were used in the assessment of the status of the species. The new species is highly disjunct, known from Finland and Russian Far East. A list of Finnish crane flies was presented, including the presence of species in the Finnish biogeographical provinces (III). A total of twenty-four species were formally reported for the first time from Finland and twenty-two previously reported species were deleted from the list. A short historical review on the studies of Finnish crane flies has been provided. The current list of Finnish species consists of 338 crane flies (IV, Appendix I). Species richness of all species and saproxylic/fungivorous species is negatively correlated with latitude, but mire-dwelling species show a reversed species richness gradient (i.e. an increase in the number of species toward north). Provincial assemblages displayed a strong latitudinal gradient and faunistic distance increased with increasing geographical distance apart of the provinces. Nearly half (48 %) of the Finnish crane flies are Trans-Palaearctic, roughly one-third (34 %) are West Palaearctic and only 16 and 2 % are Holarctic and Fennoscandian, respectively. Due to the legacy of Pleistocene glaciations, endemic Fennoscandian species are problematic and it is thus concluded that there are probably no true endemic crane flies in this region. Finally, there are probably species living within Finnish borders that have hitherto remained unnoticed. Based on subjective assessment, the number of “true” (i.e. recorded + unknown species) species count of Finnish crane flies is at minimum 350.

The genus Habenaria (Orchidaceae) in the Brazilian Amazon

A survey of Habenaria in the Amazon region in northern Brazil was undertaken. Forty species are recognized for the region. The majority of the species occur in savannah vegetation and the vegetation types with the highest number of species are the inland savannahs on terra firme (19 spp.), the savannahs of Roraima (16 spp.) and the coastal savannahs of Pará and Amapá (15 spp.). Only four species grow in forest and three in the Amazonian caatinga. Nine of these species are restricted in Brazil to the Amazon region, four species from forest formations and three from highlands at the border with Venezuela. Only one species, H. sylvicultrix Lindl. ex Kraenzl., is possibly endemic to northern Brazil. When compared to other regions, the greatest similarity is found with the "cerrado" of the centralwestern region (28 spp. in common) and the Guianas (26 spp.). Only five species are common with the Atlantic Forest. Five species are recorded for the first time or confirmed in Brazil: H. avicula Schltr., H. dentifera Schweinf., H. huberi Carnevali & Morillo, H. lehmanniana Kraenzl. and H. seticauda Lindl. New synonyms are proposed and Habenaria marupaana Schltr. is included under the synonymy of H. amambayensis Schltr., H. platydactyla Kraenzl. under H. schwackei Barb. Rodr., H. mitomorpha Kraenzl. under H. subfiliformis Cogn., and H. pratensis (Salzm. ex Lindl.) Rchb. f. var. parviflora Cogn. under H. spathulifera Cogn.

Taxonomic survey of Paepalanthus section Diphyomene (Eriocaulaceae)

Paepalanthus is the largest genus in Eriocaulaceae, comprising about 400 species distributed mainly throughout the Neotropics. Through phylogenetic studies it has been demonstrated that the genus is polyphyletic, although many of its infrageneric categories are monophyletic. In an attempt to clarify the nomenclature and classification of Paepalanthus, we present a taxonomic survey of Paepalanthus section Diphyomene. This group consists of 10 species restricted to South America and is defined by inflorescences being arranged in the form of a tribotryum with terminal dibotryum, a terminal basic unit and pherophylls subtending the lateral dibotrya. Further important distinguishing characteristics are dimerous flowers, pistillate flowers with dolabriform sepals, bifid stigmatic branches and absent staminodes, and staminate flowers with an elongated anthophore. We hereby propose 19 new synonyms, six lectotypifications, one new status, one neotypification and one epitypification.

Linnaeus's Plantae Surinamenses revisited

In 1775, Jacob Alm defended the Linnaean dissertation Plantae Surinamenses under the precidency of Carolus Linnaeus. In this account of Surinamese plants preserved in alcohol, given to Linnaeus by the King Gustavus III of Sweden, 148 species were treated, 117 of them with species names determined. Fifteen other species were indicated as new, but were neither described nor named, and 16 species were identified only to genus level. Here, the taxonomic identity and nomenclatural status of those names are updated and discussed. Five of the 117 names and also 11 of their synonyms, a species name described by Rottboll and ten described by Linnaeus filius are lectotypified. Two new combinations and a new name are proposed, and two new synonyms are established.

The lauraceae collected in brazil by ludwig riedel - II. Ocotea

The species of Ocotea (Lauraceae) collected by Ludwig Riedel are commented and contextualized according to the different itineraries he travelled in Brazil, from 1821 to 1836, indicating the localities and dates of collections, whenever possible. To complete this work, two diaries of Riedel have been consulted and the information from them crossed-checked with the annotations found on specimen labels. An annotated list of 44 entries provides information on the status of species names and their types, currently accepted names, and collections found in different herbaria. Lectotypes for 19 names are designated, two new synonyms are proposed, as well as the new combination Ocotea estrellensis (Meisn.) P.L.R. Moraes, based on Oreodaphne estrellensis Meisn. © President and Fellows of Harvard College, 2012.

Revision of Hista Oiticica (Lepidoptera: Castniidae) and discussion on the validity of its subspecies

Diurnal Lepidoptera tend to have colorful and conspicuous wing patterns, which is the reason the first classifications of day-flying moths and butterflies were based mainly on wing color and pattern characters. This is the case with the Neotropical Castniidae, which are usually large and colorful day-flying moths. One classification listed 134 species in 32 genera while an alternate classification recognized 81 species. In this paper we examine the taxonomic structure of the genus Hista Oiticica. It is the purpose of this paper to evaluate taxonomically useful characters besides wing pattern with the goal of classifying the taxa of Hista rather than classifying the variation of its wing pattern. In so doing, the results resolve the differences between the two proposed classifications of Hista. In addition, a lectotype is designated for Castnia boisduvalii Walker, 1854 (new synonym of Castnia fabricii Swainson, 1823) to ensure the stability of the name. Other new synonyms are proposed for C. fabricii (C. papagaya Westwood, 1877) and Castnia hegemon Kollar, 1839 (C. menetriesi Boisduval, [1875] and C. hegemon variegata Rothschild, 1919).
