The Collapsible Light Trap: a portable Pennsylvania Light Trap for collecting aquatic insects.

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.

Taxonomic diversity of Ochrotrichiinae (Trichoptera: Hydroptilidae) from Peru with the description of ten new species, a new distributional record, and an updated checklist.

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.

The caddisflies from Serra dos rgos National Park, Rio de Janeiro, Brazil, with the description of two new species of Ochrotrichia Mosely (Trichoptera: Hydroptilidae: Ochrotrichiinae).

The Serra dos rgos National Park (PARNASO) is a federal conservation unit located in Rio de Janeiro State, within the Atlantic Forest biome. This biome is one of the worlds biodiversity hotspots and has high diversity and endemism of caddisfly taxa. Here, we present a checklist of caddisflies from PARNASO, including the description of two new species of Ochrotrichia Mosely (Hydroptilidae).

Three new species of Flint microcaddisflies from Peru (Insecta: Trichoptera) including DNA-based larval associations.

In this paper, we have described and illustrated three new species of from Peru: , , and Larvae of the latter two were also associated to male specimens based on comparison of a fragment of COI gene and pharate male identification. and share a unique feature: a semi-dome process formed by a thickened area on male forewings. The three species can be easily identified by wing coloration and male genitalia.

A review of the Neotropical microcaddisfly genus Acostatrichia Mosely, 1939 with description of a new species from Brazil (Trichoptera: Hydroptilidae: Leucotrichiinae).

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.

A new species of Smicridea McLachlan 1871 (Trichoptera: Hydropsychidae) from the Caatinga biome and new distributional records from Brazil.

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.

Taxonomic study of the genus Eaton 1873 (Trichoptera: Hydroptilidae) from Northeast Brazil: Eleven new species and distributional records.

The genus Oxyethira comprises over 200 species distributed worldwide. In Brazil, 23 species have been recorded, mostly from the North Region, but this number is still an underestimate. To date, six species have been recorded from the Northeast Region of Brazil (from Ceará, Piauí, and Pernambuco states).

Aquatic Insects from the Caatinga: checklists and diversity assessments of Ubajara (Ceará State) and Sete Cidades (Piauí State) National Parks, Northeastern Brazil.

Background: Diversity and distribution of Neotropical aquatic insects is still poorly known, with many species to be recorded and many others to be described, due to the small number of taxonomists and sparse faunistic studies. This knowledge is especially poor in the Caatinga Domain in Northeastern Brazil, even though, this region may have played an important historical role in the spatial evolution of faunas of forested areas in northern South America.

New Information: Aquatic insect checklists of 96 species from Parque Nacional de Ubajara (Ceará State, Brazil) and 112 species from Parque Nacional de Sete Cidades (Piauí State, Brazil) are presented, representing the following taxa: Elmidae, Epimetopidae, Hydrophilidae, and Torridincolidae (Coleoptera), Hemerodromiinae (Diptera: Empididae), Ephemeroptera, Gerromorpha and Nepomorpha (Hemiptera), Odonata, Plecoptera, and Trichoptera.

Three new species of Stactobiinae (Trichoptera: Hydroptilidae) with the first record of Orinocotrichia Harris, Flint & Holzenthal from Brazil.

Approximately 300 species are assigned to Stactobiinae, most of them occurring in the Old World. Seven species have been recorded from Brazil, six of Flintiella and one of Bredinia. Herein, three new species are described and illustrated based on specimens collected in Maranhão and Piauí states from Northeastern Region of Brazil: Orinocotrichia angelus sp.

Description of a new species of Betrichia Mosely 1939 from Brazil and edescription of the type-species (Trichoptera: Hydroptilidae: Leucotrichiinae).

Betrichia Mosely 1939 was erected to include a single species, B. zilbra Mosely 1939 from Brazil. The genus has a complicated taxonomy mainly because of the lack of diagnostic characteristics in the original description.

Integrative taxonomy of Metrichia Ross (Trichoptera: Hydroptilidae: Ochrotrichiinae) microcaddisflies from Brazil: descriptions of twenty new species.

Metrichia is assigned to the Ochrotrichiinae, a group of almost exclusively Neotropical microcaddisflies. Metrichia comprises over 100 described species and, despite its diversity, only one species has been described from Brazil so far. In this paper, we provide descriptions for 20 new species from 8 Brazilian states: M.

First records of Ochrotrichia Mosely, 1934 (Trichoptera: Hydroptilidae) in Northeastern Brazil: Five new species and two new geographical records.

About 170 species have been assigned to the New World genus Ochrotrichia, only two of which were previously recorded from Brazil. Material collected in Bahia and Ceará states represent the first records of this genus from Northeastern Brazil and reveal five new species of Ochrotrichia. These are described and illustrated in this paper: O.

A new species and new records of microcaddisflies (Trichoptera: Hydroptilidae) from northeastern Brazil.

The Hydroptilidae constitute the most diverse and widespread family of Trichoptera in the world. About 90 species of microcaddisflies have been recorded from Brazil, but the northeastern region is one of the least-sampled. In this work we describe a new species of Metrichia from Pernambuco State.
