The menaced and poorly-known waters of the Bodoquena Plateau revealed a new resident, the stunning Hypostomus froehlichi sp. n., a large-sized armored catfish, which is finally described after more than twenty years since its discovery. The Bodoquena Plateau is drained by the rio Paraguay basin, and is located in the state of Mato Grosso do Sul, Brazil. The new species differs from its congeners on the Bodoquena crystalline waters by having teeth with morphological and numerical variation in adult specimens. There is a continuous range of specimens having about 20 thick and worn teeth to specimens having about 50 thin teeth with intact crowns and lanceolate main cusps. Additional diagnostic characters are: dentaries angled more than 90 degrees, dark blotches, one plate bordering supraoccipital, moderate keel along dorsal series of plates, usually two rows of blotches per interradial membrane on dorsal, pectoral and ventral fins, and by attaining comparatively large size. Hypostomus froehlichi seems to be endemic to the area of the Bodoquena Plateau, in rivers draining to the rio Miranda. The description of the new species reveals a potential conservation flagship species as it is one of the most seen and documented fish by visitors and divers in the clear waters from the touristic, though menaced, Bonito region in Brazil.

The southern cone of Mato Grosso do Sul state is poorly known in terms of mammal community composition. This information is very important to propose an environmental management plan. The present study provides information on the composition of medium and large size mammals in the municipality of Batayporã, in the Ivinhema river basin, southwestern Brazil. The mammal community was sampled during 19 field sampling occasions by the identification of vestiges, such as burrows, feces, vocalization and tracks, as well as through direct observations. I recorded 24 mammal species distributed in eight taxonomic orders. Thirteen species were frequently recorded, six species were rarely recorded, and six species are considered threatened in Brazil or in global level. The area presents almost half of the medium and large-sized mammal fauna from Mato Grosso do Sul state, but fragmentation and sugarcane plantations may represent a threat to the local biodiversity conservation.

This research evaluated the in vitro acaricidal activity of extracts from 21 plant species from the Pantanal of Mato Grosso do Sul. During stage I, a larval immersion test was performed using three extract concentrations (5%, 20%, and 40%). During stage II, we used only plants that showed over 95% efficiency at the 40% concentration in stage I in an amount sufficient for the adult immersion test. Aeschynomene denticulata, Angelonia hirta, Aspilia latissima, Caperonia castaneifolia, Centratherum punctatum, Crotalaria micans, Diodia kuntzei, Echinodorus paniculatus, Hyptis mutabilis, Lantana canescens, Melanthera latifolia, Ocotea diospyrifolia, Richardia grandiflora, Sebastiana hispida, Tocoyena formosa, Zanthoxylum rigidum, and Sesbania virgata (fruit extract) showed acaricidal activity against the larval stage ofRhipicephalus (Boophilus)microplus higher than 95% at a 40% (w/v) concentration, while Hippocratea volubilis and Randia armatashowed moderate efficacy and Croton glandulosus andSenna obtusifolia had no effect. The M. latifolia, A. hirta, R. grandiflora, and A. latissima raw extracts were evaluated for their activity against adults, and only A. hirta showed an efficacy close to 90%. Eighteen extracts had an efficacy of up to 95% against larvae at a 40% concentration, seven extracts were effective at 20%, and only one (Sebastiana hispida) was effective at a 5% concentration.

A New Species

A new species of Elachistocleis from the Brazilian Pantanal is described. The new species differs from all other Elachistocleis in having the following combination of characters: medium to large-sized species (26.9–40.3 mm); head length about 89% of head width; post-commissural gland poorly developed; dorsum in preservative (EtOH 70%) slightly rough, grayish, with minute, scattered white dots and a large, elongated dark gray spot on the mid-dorsum and posterior part of head; venter gray or brown with white spots separating dorsal and ventral regions; a single vocal sac dark gray; large, irregular, light cream spot on humerus; large, irregular light cream spots on groin; light cream, irregular stripe on posterior surfaces of thighs; and irregular, light cream spots on the proximal internal surface of each shank. This new species increases the number of Oval frogs for the state of Mato Grosso do Sul to four and demonstrates the value of the single protected area in Corumbá for biodiversity conservation. Continuing field investigations in the Maciço do Urucum are necessary to determine the diversity of the herpetofauna in that region.

Neste trabalho foi realizada uma avaliação sobre a presença de anticorpos anti-Leishmania infantum chagasi em cães domésticos das áreas urbanas e rurais da região do Pantanal brasileiro usando técnicas sorológicas. Um total de 429 cães foram amostrados em três áreas do bioma do Pantanal, incluindo os municípios de Poconé, Santo Antônio de Leverger e Barão de Melgaço, em Mato Grosso, e o município de Corumbá, em Mato Grosso do Sul. A reação de imunofluorescência indireta (RIFI) foi utilizada para detectar anticorpos (ponto de corte de 40) de Leishmania infantum chagasi como antígeno. Devido à possibilidade de reação cruzada entre as espécies do gênero Leishmania, as amostras positivas na RIFI para L. infantum chagasi foram também avaliadas na RIFI utilizando L. amazonensis e L. braziliensis como antígenos. As amostras positivas na RIFI para L. infantum chagasi foram avaliadas utilizando o ensaio de imunoadsorção ligado à enzima (ELISA). Os resultados mostraram a presença de anticorpos contra L. infantum chagasi em 23 (5,36%; IC 95%: 3,50% -8,05%) cães e pelo menos um cão soro-reativo foi encontrado em todos os municípios avaliados neste estudo. Os títulos de anticorpos variaram de 40 a 5.120 e todas as amostras positivas na RIFI foram positivas no ELISA. Entre os 23 cães positivos, nove também reagiram para L. amazonensis e L. braziliensis. A ocorrência de anticorpos anti-L. infantum chagasi em cães foi maior nas áreas rurais (7,06%) do que nas áreas urbanas (2,50%) (P < 0,05). Com base neste estudo, concluímos que cães de áreas rurais do Pantanal tiveram contato com espécies de Leishmania, o que é uma informação relevante, dada a sua importância para a saúde pública.

Pantanal Wetland

During a survey conducted in the Cuiabá and Paraguay Rivers in the Brazilian Pantanal wetland, in the states of Mato Grosso and Mato Grosso do Sul, we found branchiurans associated with Pseudoplatystoma reticulatum, Pseudoplatystoma corruscans, Salminus brasiliensis and Zungaro zungaro. These branchiurans correspond to Argulus chiropteroideus sp. n., Argulus multicolor, Argulus nattereri, Argulus pestifer, Dolops carvalhoi and Dolops longicauda. Besides the description of the new species, in this study we also provide important morphological notes for diagnosis of the other species. Specimens of Argulus chiropteroideus sp. n. were collected from skin of P. reticulatum and P. corruscans. They differ from A. multicolor and Argulus chicomendesi, in the shape of the postantennal spines, which is medially convex and has two lateral and one anterior stout tips in the new species, and for having three claviform, digitate spines on the base of the second maxillae (absent in A. multicolor; three conical, short spines in A. chicomendesi). A. chiropteroideus sp. n. do not have an anterior and a posterior spine on first two segments of first antenna, as well as no flagellum on the dorsal surface of the first two pairs of legs, structures present in A. multicolor and A. chicomendesi. The new species also differ from A. multicolor and A. chicomendesi, in the shape and number of sclerites that compound the support rods of the suction cup.

AbstractLocated in southwestern Brazil, the Pantanal is a Wetland of International Importance and Biosphere reserve. It is composed of several subregions, each with distinct vegetation, and hosts diverse bat fauna. The goal of this study was to compare the bat communities between different subregions of the Pantanal, especially poorly sampled areas. From February 2008 to November 2009, we surveyed bats using mist nets at five sites with different vegetation structure and hydrology, over an area of 30,000 km2. Fecal samples were also collected. We captured 254 bats belonging to six families and 37 species: Phyllostomidae (19), Vespertilionidae (8), Molossidae (8), Noctilionidae (1), Emballonuridae (1) and Natalidae (1). The most abundant species wasArtibeus planirostris(32%). The species reported in this study represent 60% of bat species recorded in Mato Grosso do Sul and 71% of species known from the Pantanal region of the state. We also highlight important records for the Pantanal, includingEumops patagonicus,Eptesicus diminutusandMicronycteris sanborni. The most common plant species in the feces of bats were from the generaCecropiaandFicus. The community of bats in the Pantanal proved rich and diverse, with differences among subregions, possibly reflecting their complex landscape and different habitats.

The aim of the study was to identify among the phlebotomine fauna potential leishmaniasis vectors. The study was carried out in Corumbá county, State of Mato Grosso do Sul, Mid-West Brazil (18º59'S, 56º39'W). Sand fly captures were undertaken fortnightly with automatic light traps at 11 sites in forested environments and anthropic areas from April 2001 to July 2003. A total of only 41 specimens were captured. Thirty-one percent of the specimens were captured in forests and 68.3% in anthropic areas. The predominance of non-anthropophilic groups and the low density of N. whitmani, a known cutaneous leishmaniasis vector, does not seem to indicate any actual risk of the transmission of this disease in the study area.
