RESUMO
A Collapsible Light Trap (CLT) for collecting insects, particularly aquatic insects, is described here. CLT is a modified Pennsylvania Light Trap with the advantage of being collapsible and lightweight to be carried in a small backpack and very easy to set up in the field. CLT is equipped with LED light strip wrapped around a PVC tube and can be connected to a regular 12 V / 7 Ah battery, running for more than 48 uninterrupted hours. Complete CLT weighs 0.8-1.0 kg, depending on the metal used, and the battery weighs around 2 kg, being easily transportable to more remote collecting areas. Over the years, CLTs have been used for collecting and describing the diversity of aquatic insects from Brazil, particularly caddisflies. Depending on the locality, only one trap for one night can collect over a thousand insect specimens and more than 200 individuals of caddisflies.

We describe here ten new species of Ochrotrichiinae from southern Peru in genera Metrichia (7 new species), Ochrotrichia (1 new species), and Rhyacopsyche (2 new species). In addition to describing and illustrating male genitalia of the new species, we also highlight diagnostic features from antennae, head setal warts, and wing venation. These structures have received little attention in taxonomic studies of Hydroptilidae, and we think they may be useful in future morphological studies involving the family. We also record O. puyana for the first time from Peru, which was previously known only from Ecuador. Comments on the distribution of the Peruvian Ochrotrichiinae are also provided, along with a distributional map and an updated checklist of the species recorded in the country. This work revealed a total of 56 species of Ochrotrichiinae from Peru.

Ibyacerina caparao new genus, new species (Trichoptera: Leptoceridae) is described and illustrated from specimens collected at Serra do Capara, Minas Gerais, Brazil. The monotypic genus is characterized by tibial spur formula 0,2,2; preanal appendages originating from a single base with a median process; tergum X broad, heavily sclerotized, saddle-like, wider at apex, and upturned, bearing small stout setae; inferior appendages each 3-branched, setose; and phallic apparatus tubular, curved slightly ventrad, with pair of lateral processes. Phylogenetic Bayesian and maximum likelihood analyses based on concatenated cytochrome oxidase I (COI) and carbamoyl-phosphate synthetase (CAD) partial sequences (1,504 bp) including representatives of 38 leptocerid genera positioned Ibyacerina gen. nov. with good support within Leptocerinae. However, due to low branch support of most relationships among genera within the clade of Leptocerinae, except Mystacidini, Setodini, and Leptocerini, its close affinities and tribal placement are still unknown.

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. nov. and provide additional data on the richness and distribution of Leptoceroidea from Parque Nacional do Caparaó and surrounding areas. The distribution of some species is expanded. Fourteen and four species are recorded for the first time from Espírito Santo and Minas Gerais states, respectively.

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. The pupa differs from other Phylloicus pupae by the sequence and shape of tergal abdominal hook plates. The case of P. obliquus larvae is composed of rectangular fragments of vegetal material with uniform shape and always arranged in overlapping layers. Larvae were found in a small second order Atlantic Forest stream.

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. In this paper, we describe, diagnose and illustrate six new species of Helicopsyche subgenus Feropsyche from Rio de Janeiro state, Brazil: Helicopsyche bendego sp. nov., H. daome sp. nov., H. dinoprata sp. nov., H. luziae sp. nov., H. petri sp. nov., and H. shaamunensu sp. nov. Furthermore, H. (F.) planorboides is redescribed based on the holotype and additional specimens; the type series of this species is now deposited in the collection of the Departamento de Zoologia, Instituto de Biologia, Universidade Federal do Rio de Janeiro. Finally, Helicopsyche (F.) catoles, H. (F.) guara and H. (F.) planorboides are reported for the first time from Rio de Janeiro state, Brazil, the last one also listed for Espírito Santo state, Brazil.

The genus Alterosa Blahnik (2005), with 39 extant species, is endemic to Atlantic Forest areas of southern and southeastern Brazil. Herein, we describe and illustrate two new species from Rio de Janeiro state, southeastern Brazil: Alterosa cornuta sp. nov., easily diagnosed by the horn-like intermediate appendages crossing each other, and A. araras sp. nov., recognized mainly by the extremely developed basodorsal protuberance on tergum X and by the rod-like, mesally curved preanal appendages, with at least 2 stout spine-like setae positioned at mid length and with the apex cupped. Additionally, a new distributional record for Espírito Santo state, southeastern Brazil, is provided for Alterosa falcata Blahnik (2005).(AU)

A new species of Smicridea (Smicridea) McLachlan 1871 is described and illustrated based on specimens collected from the Caatinga biome, in Sete Cidades National Park, Piauí state, and Ubajara National Park, Ceará state, northeastern Brazil. Based on phallus morphology, Smicridea (Smicridea) caatinga sp. nov. belongs to the S. nigripennis Group and can be distinguished from other species in this group due to the phallus having two ventral sclerotized projections and, when expanded, two dorsal membranous lobes and one ventrolateral membranous lobe with two spines on the apex. New distributional records of Smicridea species are provided for different Brazilian states: S. (S.) aequalis Banks 1920 for Ceará and Piauí, S. (Rhyacophylax) coronata Flint 1980 for Rio Grande do Sul and Piauí; S. (R.) jundiai Almeida Flint 2002 for Mato Grosso; S. (R.) marlieri Flint 1978 for Roraima; S. (R.) palmar Sganga 2005 for Goiás; S. (S.) paranensis Flint 1983 for Ceará and Piauí; and S. (R.) spinulosa Flint 1972 for Rio Grande do Sul. Furthermore, S. (S.) erecta Flint 1974b is recorded for the first time for Brazil, in Amazonas state. [Zoobank: urn:lsid:zoobank.org:act:3C2892F9-D430-492B-98DA-A48569253A63].

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. Ochrotrichia nematomorpha sp. nov. is placed within the O. xena Group, having a plate-like tergum X, with an unusual phallus which is slender and pointed apically. Ochrotrichia sagitta sp. nov. and O. taunay sp. nov. belong to the O. aldama Group, each having a divided tergum X, but being distinguished from the others in this group by the arrowhead-like apex of left lateral process of tergum X (O. sagitta) and the presence of two dorsal spine-like projections on tergum X (O. taunay). Furthermore, O. caatinga Souza, Santos Takiya, 2014 is reported for the first time from Rio de Janeiro state.
