Nine new species of the genus Thottea, namely T. anthonysamyi, T. kamarudiniana, T. longipedunculata, T. papilionis, T. piscodora, T. reflexa, T. ruthiae and T. terengganuensis from Peninsular Malaysia (eight species) and T. praetermissa from Peninsular Malaysia and Singapore (one species) are described and illustrated. Distribution maps are provided and conservation status is assessed for the new species. Thottea dependens and T. tricornis are redefined and T. parviflora is lectotypified. Thottea is now represented by 16 species in Peninsular Malaysia and two in Singapore. A spherical-ovoid shaped perianth with an aperture at the top is observed for the first time in Thottea. The white and bicoloured perianth are described for the first time in Peninsular... |

Begonia fulgurata, a new species from northern Thailand, is here described and illustrated. Begonia fulgurata resembles B. integrifolia, a widespread species in Southeast Asia, in having tubers, erect stem with hairy leaves and a periodically dormant habit. However, the new species is sharply distinct in its lamina densely hirsute (vs sparsely puberulous) and with maroon patches and silvery white veins (vs uniformly green or with white spots); inflorescence densely clothed with glandular hairs (vs glabrous or puberulous); staminate flowers with 2, rarely 3 (vs 4) tepals; staminate and pistillate tepals glandular hairy (vs glabrous). As a deciduous species with basal tubers, together with an erect stem, ovate to broadly ovate leaves, 3-locular ovary, it may... |

A review of new data relating to Nepenthes insignis in Indonesia indicates that three taxa in section Insignes, not one, are present in New Guinea. One of these, endemic to the limestone of the island of Biak, is formally named as Nepenthes biak and assessed as Critically Endangered; the other, from limestone of the Raja Ampat islands is provisionally distinguished as Nepenthes sp. Raja Ampat, since only images are available. |

Trichomycterus maracaya, a new species of Trichomycteridae, is described from a streamlet in the upper rio Paraná, Poços de Caldas, State of Minas Gerais, southeastern Brazil. The following putative autapomorphies distinguishes T. maracaya from congeneric species: 1) row of lateral blotches not forming a stripe at any phase during ontogeny; 2) superficial layer of pigmentation of juveniles and large (presumably adults) specimens consisting solely of scattered chromatophores. Furthermore, the new species is characterized by a combination of yellow ground color in life and mottled pattern formed by small to medium-sized, brown, irregularly-coalescent, well-defined deeper-lying blotches, and more superficial dots on the body. Trichomycterus maracaya is... |

ABSTRACT A new species in the serrasalmid genus Myloplus is described from the middle Mazaruni River, Essequibo River basin, Guyana. The new species is similar to Myleus pacu and Myloplus planquettei in its silver to purplish black coloration and its overall morphology, and has a putative syntopic distribution with those species. The new species is, however, readily distinguishable from the other two by meristic counts of the unpaired fins and by differences in color pattern, primarily in males. Additionally, we provide comments on Myleus pacu and other species that have been confounded under that name. |

The influence of tank color on the visual perception of fish larvae and the success of their cultivation depends on the characteristics of each species combined with environmental factors. In this study, we determined the effect of light and dark tank colors on the larviculture of pacamã (Lophiosilurusalexandri), a species with a benthonic habit, and curimatá-pioa (Prochilodus costatus), which swims actively in the water column. Larvae of pacamã and curimatá-pioa were cultivated for 10 days in 5-L tanks, at a density of 15 larvae L-1 and luminosity of 141.7 ± 8.95 lux, and fed Artemia nauplii. Four tank colors were used: green, light blue, brown, and black (with four replications). Survival, biomass and Fulton's condition factor for pacamã larvae were... |

After several years collecting in the type-localities and studying representative samples of genus Steindachneridion Eigenmann & Eigenmann, 1919 from Brazilian and foreign museums, a taxonomic revision of the Recent species of the genus is presented, including the description of a new species from the rio Iguaçu, above the great falls. Steindachneridion species are large sized fishes, reaching 1000 mm total length or more, and sharing some anatomical characters that, at least tentatively, support the monophyly of the genus. In addition to the general features found in the Pimelodidae, the species S. amblyurum (Eigenmann & Eigenmann, 1888), S. parahybae (Steindachner, 1877), S. doceanum (Eigenmann & Eigenmann, 1889), S. scriptum... |

The present study analyzed the sexual development, sizes at maturity and morphometric relationships for both sexes of Sympterygia acutaand S. bonapartii, endemic of south-western Atlantic Ocean. The examined specimens were obtained through research cruises and commercial fishing trips, during 2011 and 2012, along the southern Brazilian coast, in latitudes ranging from 34°28'S to 31°29'S and at depths between 15 and 142 m. Significant differences (p<0.05) in S. bonapartii and in S acutabetween sexes for the relationships total length (cm) - disc width (cm) and total length - total/eviscerated weight (g) respectively, demonstrated sexual dimorphism during the development in both species. The estimated size at maturity for males and females, respectively,... |

Development and spread of chloroquine (CQ) resistance led to its withdrawal in most malaria endemic countries. In Kenya, this occurred in 1998 when clinical efficacy dropped below 50%. Less than a decade after CQ was removed from routine use in Malawi, the drug has reversed to activity and is again effective for first-line treatment of uncomplicated malaria. There is a probability of a similar reversed activity in Kenya for more 10 years of its absence in uncomplicated Plasmodium falciparum malaria treatment. The present study was aimed at establishing the CQ resistance status in the country, 10 years after its withdrawal, by looking at high malaria transmission zone, Mbita, a malaria endemic area and some malaria epidemic areas of the Kenyan highlands.... |

Mimon koepckeae Gardner & Patton, 1972 is a poorly-known bat species, with only three known specimens, including the holotype. Its distribution is restricted to the type locality in Ayacucho Department, Peru, and surroundings. This species has been synonymized with M. crenulatum by some authors. Based on a new specimen of M. koepckeae collected from Santuario Nacional Pampa Hermosa, Junin Department, Peru, we provide an extensive morphological comparison with M. crenulatum (Geoffroy St.-Hilaire, 1803), Mimom bennettii (Gray, 1838), and Mimon cozumelae Goldman, 1914, concluding that M. koepckeae is a valid species. As a result the distribution range of the species is extended 160 km north of the type locality. In addition, we characterize the... |

We describe the nest, eggs, and nestlings of the Restinga Antwren (Formicivora littoralis), an endangered bird of Restinga ecosystem (sandy coastal plain vegetation) that is endemic to Rio de Janeiro state. Twelve nests were found at the edges of trails or natural gaps at Massambaba Restinga region, in different supporting plants and heights from the ground (X ± SD 1.27 ± 0.97 m, range 0.27 to 3.45 m). Nests were cup-shaped and were in horizontal forks attached to branches at three to five points with whitish, soft, and thin cotton-like vegetable fiber. The nests' cup shape and measurements were similar to congeneric species, but nest material was different. Eggs were white with brown spots concentrated on the large end or around the middle, giving the... |

Wood anatomy of stem and rhizome of Sophora linearifolia, a rhizomatous plant endemic to centre Argentina, is described. Structural description of thin sections and macerations includes microphotographs of optical and scanning electron microscopy. Significant anatomical differences exist between secondary xylem of aerial orthotropic shoots and underground rhizome. Both organs have absent to indistinct growth ring boundaries, simple perforation plates, alternate and vestured intervessel pits and disjunctive parenchyma cell walls. However, stems have smaller vessels, longer fibres, partial storying (vessel elements and axial parenchyma) and narrower rays. Some anatomical characters of the rhizome suggest adaptations to its sinuous pattern of growth. The stem... |
