Malaria in Brazil: what happens outside the Amazonian endemic region

Brazil, a country of continental proportions, presents three profiles of malaria transmission. The first and most important numerically, occurs inside the Amazon. The Amazon accounts for approximately 60% of the nation’s territory and approximately 13% of the Brazilian population. This region hosts 99.5% of the nation’s malaria cases, which are predominantly caused by Plasmodium vivax (i.e., 82% of cases in 2013). The second involves imported malaria, which corresponds to malaria cases acquired outside the region where the individuals live or the diagnosis was made. These cases are imported from endemic regions of Brazil (i.e., the Amazon) or from other countries in South and Central America, Africa and Asia. Imported malaria comprised 89% of the cases found outside the area of active transmission in Brazil in 2013. These cases highlight an important question with respect to both therapeutic and epidemiological issues because patients, especially those with falciparum malaria, arriving in a region where the health professionals may not have experience with the clinical manifestations of malaria and its diagnosis could suffer dramatic consequences associated with a potential delay in treatment. Additionally, because the Anopheles vectors exist in most of the country, even a single case of malaria, if not diagnosed and treated immediately, may result in introduced cases, causing outbreaks and even introducing or reintroducing the disease to a non-endemic, receptive region. Cases introduced outside the Amazon usually occur in areas in which malaria was formerly endemic and are transmitted by competent vectors belonging to the subgenus Nyssorhynchus (i.e., Anopheles darlingi, Anopheles aquasalis and species of the Albitarsis complex). The third type of transmission accounts for only 0.05% of all cases and is caused by autochthonous malaria in the Atlantic Forest, located primarily along the southeastern Atlantic Coast. They are caused by parasites that seem to be (or to be very close to) P. vivax and, in a less extent, by Plasmodium malariae and it is transmitted by the bromeliad mosquito Anopheles (Kerteszia) cruzii. This paper deals mainly with the two profiles of malaria found outside the Amazon: the imported and ensuing introduced cases and the autochthonous cases. We also provide an update regarding the situation in Brazil and the Brazilian endemic Amazon.

O subgênero Centris (Aphemisia) Ayala: notas complementares e descrição de uma nova espécie (Hymenoptera, Apoidea)

The subgenus Centris (Aphemisia) Ayala: complementary notes and description of a new species (Hymenoptera, Apoidea). Centris (Aphemisia) Ayala, 2002 is redescribed pointing out some others important distinctive characters. The nominal species designated by Ayala as the type species, Centris plumipes Smith, 1854, is preocupied by Centris plumipes (Fabricius, 1781) originaly described in Apis Linnaeus. Being so, Centris xanthosara nom. nov. is proposed to replace Centris plumipes Smith, 1854 non Centris plumipes (Fabricius, 1781). Two other species are considered to belong in this subgenus: Centris (Aphemisia) lilacina Cockerell, 1919, and Centris (Aphemisia) plumbea sp. nov., from Tingo Maria, Peru. A key for the species, illustrations, and geographical distribution are also added.

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.

O subgênero Centris (Schisthemisia) Ayala: notas complementares e descrição de uma nova espécie (Hymenoptera, Apoidea)

The subgenus Centris (Schisthemisia) Ayala: complementary notes and description of a new species (Hymenoptera, Apoidea). Centris (Schisthemisia)Ayala, 2002 is redescribed, pointing out some other important distinctive characters. It includes: Centris (Schisthemisia) flavilabris Mocsáry, 1899 (type species), Centris (Schisthemisia) boliviensis Mocsáry, 1899 stat. nov., Centris (Schisthemisia) fulva Friese, 1924 stat. nov., and Centris (Schisthemisia) restrepoi sp. nov. from Colombia, Villa Vicencio. A key to the species and illustrations are added.

Notas e descrições em Bisaltes Thomson, 1868 e Ptericoptus Lepeletier & Audinet-Serville, 1830 (Coleoptera, Cerambycidae, Lamiinae, Apomecynini)

(B.) unicolor sp. nov. from Ecuador. Bisaltes (B.) pictus Breuning, 1940 is transferred to the subgenus Craspedocerus. In Ptericoptus, P. hybridus hybridus Breuning, 1939 is considered a synonym of P. acuminatus (Fabricius, 1801); P. dorsalis Audinet-Serville, 1835 previously in the synonymy of P. acuminatus is revalidated and Saperda vitta Newman, 1838 is considered its synonym; P. corumbaensis sp. nov. is described from Brazil (Mato Grosso do Sul).

Drosophila angustibucca Duda sensu Frota-Pessoa is an undescribed species (Diptera, Drosophilidae)

Drosophila nappae sp. nov. , belonging to the subgroup I of the Drosophila tripunctata species group of the subgenus Drosophila, is described from flies of one strain established from several females collected from July 1994 through April 1995 at Morro Santana, Porto Alegre, state of Rio Grande do Sul, Brazil. This species has been misidentified during the past fifty years as Drosophila angustibucca (sensu Frota-Pessoa, 1954; non Duda, 1925, described from Costa Rica). Illustrations of male and female terminalia are also provided.

New enigmatic Andean bee species of Protandrena (Hymenoptera, Andrenidae, Panurginae)

Panurgine bees are diverse and abundant in temperate areas of the Americas but poorly represented to nearly absent in the tropics. We describe and illustrate five distinctive new species of the genus Protandrena that occur at high altitudes (2000-3400 m) in the Andes, from Venezuela to Ecuador. The species are also described to make the names available in forthcoming papers on their biology. These Andean species resemble some members of the subgenus Heterosarus but differ from it, as well as from any other subgenera of Protandrena, primarily in characters of the male genitalia and hidden sterna. The South American Protandrena s. l. are morphologically highly diverse and a complete study of the group is needed before supraspecific names are proposed for unusual species. Thus, to avoid further nomenclatural changes, we decided not to place these species in a new subgenus or any of the available subgenera. We also provide notes on the biology for some of the species.

Phylogeny of wasps of the genus Mischocyttarus de Saussure (Hymenoptera, Vespidae, Polistinae)

A phylogenetic analysis is presented of subgenera and species-groups of Mischocyttarus de Saussure, the largest genus of social wasps. The analysis is based on 62 morphological and nest architecture characters, coded for 71 terminals representing much of the taxonomic diversity within the genus, plus three outgroup terminals representing other polistine tribes. The main conclusions about phylogenetic relationships within the genus are based on parsimony analysis under implied weights. Monophyly of Mischocyttarus is confirmed as well as that of most of the previously recognized subgenera: Mischocyttarus s. str., Clypeopolybia, Monogynoecus, Scytokeraia, Phi, Kappa, Megacanthopus and Omega sensu Richards (1978). Haplometrobius as conceived by Richards (1978) is not a monophyletic taxon, but some of its species-groups are monophyletic. The groups of M.artifex and M.cerberus are raised to subgenus level, and a new concept of Haplometrobius restricts it to the group of M.iheringi (the type species of this subgenus) in the sense of this work. The concept of subgenus Omega is widened to include the species-groups of M.surinamensis and M.prominulus. Besides the new subgeneric classification presented, limits and diagnoses of all species-groups of the subgenera Phi and Haplometrobius sensu Richards (1978) are discussed, and a new key for all subgenera and species-groups of Mischocyttarus is also presented.

Phenetic, biogeographical, and evolutionary study ofOrnithogalum subg.Heliocharmos (Hyacinthaceae) in the western Mediterranean basin

A macromorphological study is made on taxa of the genusOrnithogalum subg.Heliocharmos in North Africa, Spain, and France. The results obtained are consistent with data from cytogenetics, reproductive biology and strategies of reproduction. They allow the retention of two species:O. algeriense and O. umbellatum. A biogeographical and phylogenetic interpretation of the subgenus is proposed for the western Mediterranean. Theoretical views on phenetics are discussed.

First record of Coprophanaeus bellicosus (Olivier) (Coleoptera, Scarabaeidae) in a "Brejo de Altitude" forest in northeastern Brazil: a historical biogeographical approach

First record of Coprophanaeus bellicosus (Olivier) (Coleoptera, Scarabaeidae) in a "Brejo de Altitude" forest in northeastern Brazil: a historical biogeographical approach. This note presents the first record for a species of dung beetle of the genus Coprophanaeus, subgenus Megaphanaeus, in a "Brejo de Altitude" forest. Besides the new record, the paper discusses biogeographic aspects of the species and subgenus, as well as of the natural history of the "Brejos de Altitude", unique ecosystems in the northeast region of Brazil.

Description of the male of Lepidodexia (Xylocamptopsis) teffeensis (Townsend) (Diptera, Sarcophagidae)

Description of the male of Lepidodexia (Xylocamptopsis) teffeensis (Townsend) (Diptera, Sarcophagidae). The male of Lepidodexia (Xylocamptopsis) teffeensis (Townsend, 1927) is described and illustrated for the first time based on material housed in the entomological collection of Museu Nacional, Rio de Janeiro (MNRJ). This monotypic subgenus has been recorded in the Brazilian Amazon Rainforest, first in the state of Amazonas and now in the state of Pará. The general structure of the male terminalia is similar that of other Lepidodexia, especially of the subgenus Lepidodexia, by the short distiphallus, juxta with apical projection, and vesica with a membranous spinous lobe.

Notes on the systematics of the orchid-bee genus Eulaema (Hymenoptera, Apidae)

Notes on the systematics of the orchid-bee genus Eulaema (Hymenoptera, Apidae). The classification of the genus Eulaema is modified in order to make it congruent with recent phylogenetic hypotheses based on molecular data. The speciosa group, containing E. peruviana, E. speciosa and related species, is removed from E. (Eulaema) and transferred to E. (Apeulaema). New morphological characters are presented to support the revised scope of the subgenera and their diagnostic features are revised. Six species groups are recognized herein: two in E. (Apeulaema) and four in E. (Eulaema). A list of valid species in each species group and an identification key to males of each of the subgenera and species groups are provided. Finally, an older overlooked designation of a type species for Eulaema is presented in the Appendix.
