Complementary studies of the Perlidae (Insecta: Plecoptera) fauna from the Paranapiacaba Mountains using DNA barcode data.

The Paranapiacaba Mountains are a region of Brazil where the stonefly fauna is relatively well known. Despite this, there are still gaps in knowledge that need to be filled. In this study, through field sampling and molecular analyses, we have updated the taxonomic knowledge of Perlidae species in this region.

An integrative approach to the study of Kempnyia Klapálek, 1914 (Plecoptera: Perlidae) from Brazil: Support for the description of four new species and a basis for future studies.

Kempnyia (Plecoptera: Perlidae) is an endemic genus of Brazilian stoneflies that has 36 valid species and is distributed primarily in the Atlantic Forest and the mountainous areas of Central Brazil, particularly in Goiás and Tocantins states. Despite being the Brazilian genus with the most DNA sequences available on GenBank, integrative studies on the genus began only recently, in 2014. In this context, herein we studied the morphology and molecular data of Kempnyia specimens deposited in the Aquatic Biology Laboratory (UNESP, Assis) and the Entomology Museum of the Federal University of Viçosa (UFVB, Viçosa) collections.

A synopsis of the genus Cylindrostethus Fieber 1861 (Insecta: Hemiptera: Gerridae).

Cylindrostethus Fieber, 1861 is one of the most striking genera of water striders (Insecta: Hemiptera: Gerridae) and has Pantropical distribution. Members of this group can be recognized by the very long, cylindrical body; the short antennomere IV; the short labium not reaching the mesosternum; and by characteristics of the abdomen of males and females. Although Neotropical representatives of the genus have been revised, there are pending taxonomic issues related to this fauna, and that of the Eastern Hemisphere has been barely studied in recent years.

Taxonomic Revision, Morphology and Natural History of the Stick Insect Genus Serville, 1831 (Insecta: Phasmatodea).

Stick insects (Phasmatodea) are quite diverse in the Neotropical region. Among them, Serville belongs to Pseudophasmatidae and comprises winged, roughly brownish phasmids that resemble bark or dry branches and inhabit the Atlantic Forest in Brazil. In this study, we present a redescription and revision of the genus that include three valid species, , , and sp.

Taxonomic Contributions on Macrogynoplax Enderlein and Enderleina Jewett (Plecoptera: Perlidae) from Brazil, Including a New Species Supported by Molecular and Morphological Data.

Stoneflies (Plecoptera) are aquatic insects widely used in ecological and monitoring studies as indicators of environmental quality due to their high sensitivity to pollution. Among Brazilian Plecoptera, Perlidae is the most diverse family, with four genera (Anacroneuria Klapálek 1909, Enderleina Jewett 1960, Kempnyia Klapálek 1914, and Macrogynoplax Enderlein 1909) and about 150 species. Herein, based on data from the barcode region of the mitochondrial cytochrome c oxidase subunit I (COI) gene and morphological characters, we studied specimens of Enderleina and Macrogynoplax, mainly from the Brazilian Savanna.

Revision of Potamobates Champion, 1898 (Hemiptera: Heteroptera: Gerridae) and description of a new genus for P. thomasi Hungerford, 1937.

Potamobates Champion, 1898 (Hemiptera: Heteroptera: Gerridae) heretofore included 18 species distributed from southern Mexico to Peru. They display a distinct morphology, especially regarding the projections of abdominal segment VIII. Specific identification and delimitation are difficult, and the genus lacks a thorough revision and evaluation of inter- and intraspecific variation.

Systematic revision and phylogeny of Paragripopteryx Enderlein, 1909 (Plecoptera: Gripopterygidae).

Among the Neotropical gripopterygids, the genus Paragripopteryx occurs along the Brazilian Atlantic coast to Uruguay. Since its first recognition by Enderlein in 1909, the genus underwent a confusing taxonomic history with some combinations. In this study, we aim to revise Paragripopteryx and present the first morphology-based phylogeny for the genus.

Perlidae (Plecoptera) from the Paranapiacaba Mountains, Atlantic Forest, Brazil: Diversity and implications of the integrative approach and teneral specimens on taxonomy.

The study of complementary sources of biological variation (e.g. morphological, molecular) has allowed a better understanding of biodiversity through the construction of an integrative taxonomy.

Five new species of Tupiperla Froehlich, 1969 (Plecoptera: Gripopterygidae).

The stoneflies of the family Gripopterygidae have a Gondwanan distribution (Australian, Neotropical, and Andean regions) and include about 300 species in five recognized subfamilies. The subfamily Gripopteryginae is restricted to the Neotropics and the Andean regions of South America, including 15 genera and about 80 species. Tupiperla Froehlich, with 20 species, is the largest genus among the South American Gripopteryginae.

Anacroneuria iporanga (Plecoptera: Perlidae): description of the nymph and biological notes.

The Neotropical stonefly genus Anacroneuria (Perlidae) is represented by approximately 80 species in Brazil, but the nymphs of only 11 of these species have been associated and described. In this paper, we describe the previously unknown nymph of A. iporanga from Intervales State Park, São Paulo State, Brazil and present biological observations for this species.

Anacroneuria flintorum Froehlich 2002 (Plecoptera: Perlidae): Notes, distribution, and life stages association using molecular tools.

Specimens of the perlid stonefly Anacroneuria flintorum from different regions of the Brazilian Atlantic Forest along the Atlantic coast of Brazil were studied. In this paper, the nymph of A. flintorum is described based on reared specimens and molecular associations.

Drivers of metacommunity structure diverge for common and rare Amazonian tree species.

We analysed the flora of 46 forest inventory plots (25 m x 100 m) in old growth forests from the Amazonian region to identify the role of environmental (topographic) and spatial variables (obtained using PCNM, Principal Coordinates of Neighbourhood Matrix analysis) for common and rare species. For the analyses, we used multiple partial regression to partition the specific effects of the topographic and spatial variables on the univariate data (standardised richness, total abundance and total biomass) and partial RDA (Redundancy Analysis) to partition these effects on composition (multivariate data) based on incidence, abundance and biomass. The different attributes (richness, abundance, biomass and composition based on incidence, abundance and biomass) used to study this metacommunity responded differently to environmental and spatial processes.

Predictive Models of Primary Tropical Forest Structure from Geomorphometric Variables Based on SRTM in the Tapajós Region, Brazilian Amazon.

Surveying primary tropical forest over large regions is challenging. Indirect methods of relating terrain information or other external spatial datasets to forest biophysical parameters can provide forest structural maps at large scales but the inherent uncertainties need to be evaluated fully. The goal of the present study was to evaluate relief characteristics, measured through geomorphometric variables, as predictors of forest structural characteristics such as average tree basal area (BA) and height (H) and average percentage canopy openness (CO).
