A New Species

A new species of Magneuptychia Forster, 1964 (Lepidoptera: Nymphalidae, Satyrinae), Magneuptychia andrei Zacca, Casagrande & Mielke sp. n., is described and illustrated from Venezuela, French Guiana, Trinidad and Tobago and northern Brazil. A comparative diagnosis between the new species and Magneuptychia ocypete (Fabricius, 1776), M. fugitiva Lamas, [1997] and Cissia terrestris (Butler, 1867) is also provided due the similarities in wing pattern.

A New Species

The Solimões Formation (Eocene-Pliocene) is a well-known geological unit due to the great diversity of crocodylian species. Here we describe a new species of Melanosuchus, M. latrubessei sp. nov., from the Talismã locality, state of Amazonas, from the Upper Miocene of the Solimões Formation (Solimões Basin, Brazil). A new phylogenetic inference focused on Caimaninae is provided and the different evolutionary scenarios involving this new species are discussed. In addition, quantitative morphology studies are carried out and comments regarding the paleoecology aspects of this new species are made. M. latrubessei represents a medium-sized generalist predator, being proportional to the medium-sized M. niger. This new species inhabited the drainages of the Solimões Formation and was ecologically related to other taxa of crocodylians during the proto-Amazon Miocene. The evolutionary advantages of Melanosuchus genus are discussed to better understand the biogeographical occurrence of M. niger in South America, a species which survives to this day in contrast to several other species that became extinct during the Miocene-Pliocene periods. The extinction of the Miocene-Pliocene crocodylian taxa of the Solimões Formation, including Melanosuchus latrubessei, seems to be directly related with the uplift of the northern portions of the Andes, which generated significantly changes in drainages and Amazon paleoenvironments.

A new species, Gabrita erwini, sp. nov. in the tribe Gabritini is described and illustrated from Ecuador, representing the first record of the genus and tribe in northwestern South America which extends its distribution across the Neotropical region from eastern localities in the countries of Brazil, French Guiana and Guyana. Three new species of Sandersellus in the tribe Sandersellini are described and illustrated: S. bigladius, sp. nov. from Bolivia, S. digitatus, sp. nov. from Brazil and S. bilanceus, sp. nov. from Peru. Brazil is a new record for the genus and tribe and extends the distribution eastward from its formerly known western range in Peru, Bolivia and Panama. Taxonomy is reviewed, a revised key to known males and distribution of the known species of Gabrita and Sandersellus are provided.

Abstract We describe Macrocentrum aurimontium (Melastomataceae: Merianieae), a new species that has been collected twice in the state of Pará, Northern Brazil. Macrocentrum aurimontium closely resembles M. latifolium, a species from French Guiana, due to its isomorphic leaves and 4-merous flowers, but differs from it by the eglandular trichomes up to 4 mm long on the adaxial foliar surface (vs. glabrous or deciduously strigulose, then the trichomes 0.1–0.2 mm long in M. latifolium), denticulate to denticulate-serrulate, always ciliate leaf margin (vs. minutely serrulate, eciliate), sepals 0.5–0.7 mm long, triangular to broadly triangular, with an obtuse to rounded apex, the external teeth projecting 0.2–0.5 mm above them (vs. sepals ca. 0.1 mm long, oblate, the external teeth with the same size as the sepals) and the fruits shorter and narrower (2.7–3.7 × 1.2–1.4 mm vs. 4–5.5 × 3.1–4 mm).

A New Species

Eugenia densiracemosa, a new species from central Brazil to French Guiana, is described, illustrated and compared to the related Eugenia egensis, from which it is set apart by the longer inflorescences, longer rachis (1.2–6.0 cm long), with 9–25 pairs of flowers, while in E. egensis the inflorescences are smaller, with rachis 0.1–0.6 cm long, and a smaller number of flowers (1–4 pairs of flowers in each inflorescence).

AbstractMichaelshaffera gen. n. is comprised of two species, M. maidoa (Schaus), new combination, the type species, described from French Guiana, and a new species, M. beckeri, here described from South America. The assignment of taxa to the Pyraloidea is based primarily on characters of the tympanal organs and immature stages. Michaelshaffera lacks a tympanal organ and the immatures are unknown. The rationale for the placement of this genus in the Pyraloidea and lower hierarchical ranks is discussed based on other morphological characters.

A New Species

The microcaddisfly genus Acostatrichia Mosely (Leucotrichiinae, Leucotrichiini) is revised. Based on morphological features of the adult male, species assigned to the genus are here divided into three species groups: A. plaumanni Group, A. brevipenis Group, and A. cerna Group. After examination of type specimens, the subjective synonymy of Acostatrichia darda Oláh & Flint, A. hosulaba Oláh & Flint, and A. pika Oláh & Flint is proposed, with the first name being chosen to have priority over the other two. Acostatrichia ketvilla Oláh & Flint is considered a junior synonym of Costatrichia nelsonferreirai Santos & Nessimian, and another 3 species are removed from Acostatrichia: A. tapada Oláh & Flint and A. rovidka Oláh & Flint are transferred to Costatrichia; and A. topora Oláh & Flint is transferred to Leucotrichia Mosely. A new species, Acostatrichia araca sp. nov. is described and illustrated from northern Brazil; descriptions and illustrations are also provided for the other 11 Acostatrichia species. After these nomenclatural acts, the genus Acostatrichia includes 15 species restricted to South America.

A New Species

Dichaea is the largest genus of the subtribe Zygopetalinae and holds it's the highest species diversity in South America. Therefore, this study aims to describe a new species of Dichaea, which occurs in northern Brazil, Dichaea bragae Valsko, Krahl & Holanda. The new species was collected in the north of Manaus in an area of ombrophilous forest and flowered when cultivated. The epithet honors Dr. Pedro Ivo Soares Braga (in memoriam), orchidologist who conducted several studies in the Brazilian Amazon. This new species show a affinity with Dichaea tenuis C. Schweinf., however it is differentiated both vegetatively and on labellum morphology.

Obtusitermes Snyder is a genus endemic to the Neotropics, restricted to northern South America and southern Central America. Obtusitermes panamae Snyder was described from Quipo, Panama. Herein, we describe Obtusitermes formosulus, n. sp., from Venezuela and Trinidad and Tobago, based on the dimorphic soldier and polymorphic worker. These descriptions provide strong evidence that Parvitermes bacchanalis Mathews should not be included in Obtusitermes.

A new species of the genus Crenitulus Winters, 1926 (Hydrophilidae: Chaetarthrinae: Anacaenini), C. clarksoni sp. nov. is described from northern Brazil and Guyana. The new species can be distinguished from other species of Crenitulus by the following combination of characteristics: body size 1.6–1.8 mm in length; clypeus, frons, pronotum and elytra black, pronotum with distinctly demarcated yellow lateral margins; presence of dorsal pubescence and longitudinal rows of coarser punctures on lateral margins of elytra; apical antennomere 1.5 times longer than wide and 2.5 times longer than antennomere 8; maxillary palpi 2.5 times longer than wide and 2.2 times longer than palpomere 3; mesoventrite nearly flat; procoxae with strong, large spines; femoral pubescence confined to anterior margin and proximal portion; by phallobase as long as parameres; by parameres narrowed apically with the apex rounded and by the median lobe slightly shorter than parameres with corona in subapical position.
