Leptoceroidea (Insecta: Trichoptera: Integripalpia) from Serra do Caparaó, Southeast Brazil, including a new species of Atanatolica Mosely (Leptoceridae).

Serra do Caparaó is an impressive mountain range between the states of Minas Gerais and Espírito Santo, Southeast Brazil, inserted within the Atlantic Forest biome, and has a mosaic vegetation composed mainly by Dense Ombrophilous Forest and rupicolous vegetation of high-altitude grasslands. This study contributes to increasing the knowledge on the Leptoceroidea fauna of the Serra do Caparaó. Herein, we describe and illustrate a new species of Leptoceridae, Atanatolica bandeira sp.

The immature stages of Phylloicus obliquus Navás, 1931 (Insecta: Trichoptera: Calamoceratidae).

Larva and pupa of Phylloicus obliquus Navás are associated, described, illustrated and compared with other Neotropical species of the same genus. The P. obliquus larva differs from the others due to the pattern of distribution of muscle scars on the head, mandibles with two teeth, and a dense row of long yellow setae on the inner margin.

New species of Helicopsyche von Siebold 1856 (Trichoptera: Helicopsychidae) from Brazil, including the redescription of Helicopsyche (Feropsyche) planorboides Machado 1957.

Helicopsyche has about 270 extant species widely distributed, with highest species diversity in tropical and subtropical areas. Currently, the genus is divided into six subgenera, with only two of them occurring in the Neotropical region. In Brazil, 28 species of Helicopsyche have been recorded, being nine in Cochliopsyche and 19 in Feropsyche.

New species and new geographical record of Ochrotrichia Mosely 1934 Trichoptera: Hydroptilidae) from Rio de Janeiro state, Brazil.

Ochrotrichia, with about 160 extant species in the New World, is the most diverse genus assigned to the Ochrotrichiinae. Despite its diversity, only eight species were previously recorded from Brazil, only one from Rio de Janeiro state. In this paper, we describe three new species from Parque Nacional da Tijuca, an Atlantic Forest area at Rio de Janeiro.

Phylloicus mirabilis (Trichoptera: Calamoceratidae), a new species from Rio de Janeiro state, southeastern Brazil.

Phylloicus Müller 1880 is an endemic Neotropical genus of Calamoceratidae characterized by adults that have diurnal to crepuscular habits. Currently, the genus contains 57 species, with 23 of these species recorded from Brazil. Herein, a new species of Phylloicus is described and illustrated based on specimens collected in Malaise traps from Southeast Region, Brazil.

Two new species of Austrotinodes Schmid (Insecta, Trichoptera, Ecnomidae) from southeastern Brazil.

The genus Austrotinodes Schmid, with 55 species described from the New World and Australia, is the second largest genus of the family Ecnomidae. Herein, we describe and figure two new species of Austrotinodes from Parque Nacional da Tijuca, Rio de Janeiro state, southeastern Brazil: A. carioca sp.

A new species of Polyplectropus Ulmer 1905 (Trichoptera: Polycentropodidae) from Minas Gerais State, southeastern Brazil.

The adult male of a new species of the genus Polyplectropus Ulmer 1905a is described and illustrated based on specimens collected in Parque Nacional da Serra da Canastra, southeastern Brazil. Polyplectropus canastra sp. nov.

Three new species and a new record of Smicridea McLachlan 1871 (Trichoptera: Hydropsychidae) from Minas Gerais state, Brazil.

Three new species of Smicridea McLachlan 1871 are described and illustrated based on specimens collected in Parque Nacional da Serra da Canastra and its surrounding area, Minas Gerais state, southeastern Brazil. Smicridea (Rhyacophylax) necator sp. nov.

Three new species and new distributional records of Oecetis McLachlan 1877 (Trichoptera: Leptoceridae: Leptocerinae) from Brazil.

The genus Oecetis is widespread over the world, being most diverse in tropical areas, especially in the Australian Region. Of about 400 described species, only 34 occur in the Neotropical Region. Herein, we describe and illustrate three new species of Oecetis from Brazil: Oecetis angelae sp.

The genus Alterosa Blahnik, 2005 (Trichoptera, Philopotamidae, Philopotaminae) in northeastern Brazil, including the description of three new species and an identification key for the genus.

Alterosa Blahnik, 2005 contains 35 described species distributed in southern and southeastern Brazil. Three new species of Alterosa from northeastern Brazil are described and illustrated, Alterosa amadoi sp. n.

A new species of the genus Alterosa (Trichoptera: Philopotaminae) from Southeastern Brazil.

Philopotamidae is a large caddisfly family with 20 extant genera comprising about 1000 described species worldwide. Alterosa contains 22 described species distributed in South and Southeastern Brazil. Adults of the genus are very similar in general structure, but are remarkable for their wide variation in male genitalic morphology.

New species of the caddisfly genus Alterosa Blahnik 2005 (Trichoptera: Philopotamidae: Philopotaminae) from Brazil.

Alterosa Blahnik 2005 contains 23 described species distributed in southern and southeastern Brazil. Twelve new species in the caddisfly genus Alterosa are described from Brazil: Alterosa affinis sp. nov.

Faunistic catalog of the caddisflies (Insecta: Trichoptera) of Parque Nacional do Itatiaia and its surroundings in southeastern Brazil.

The Atlantic Forest is considered one of the world's biological diversity hotspots, and is increasingly threatened by the rapid destruction and fragmentation of its natural areas. The caddisflies (Trichoptera) of Itatiaia massif, an Atlantic Forest highland area, are inventoried and cataloged here. The catalog is based on examination of bibliographies, field work on many localities of Itatiaia massif (including Parque Nacional do Itatiaia - PNI), and the entomological collection Professor José Alfredo Pinheiro Dutra (DZRJ), Universidade Federal do Rio de Janeiro.
