Description of two new species ofXiphocentronBrauer, 1870 (Trichoptera: Xiphocentronidae) from southeastern Brazil

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. 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.

Three new species of Xiphocentron Brauer, 1870 (Trichoptera, Xiphocentronidae) from Mexico

Three new species of the genus Xiphocentron (Trichoptera, Xiphocentronidae) are described from Nearctic and Neotropical regions of Mexico. Xiphocentron (Glyphocentron) flinti sp. nov. has a very unique morphology distinguished by the presence of long spines on the preapical and apical margin of tergum X. Xiphocentron (Antillotrichia) holzenthali sp. nov. is diagnosed by tergum IX, with the apical margin bearing a narrow, rounded, mesal emargination and by a spiny projection near the basal plate. These species are the first records of the family in northwestern Mexico. Xiphocentron (Antillotrichia) pineroi sp. nov. is recognized, when observed in lateral view, by its less elongate genitalia and the sinuous mesal sclerite of the inferior appendage. Additionally, we provide detailed illustrations of Xiphocentron (Antillotrichia) rhamnes Schmid, and an updated list of the distribution of the genus Xiphocentron in Mexico.

Leptoceridae (Insecta, Trichoptera) from Serra da Canastra Mountain Range, Southeast Brazil: Diversity, Distribution, and Description of Two New Species

The Brazilian savanna, also known as Cerrado, is one of the world's biodiversity hotspots, covering about 22% of the country. Nevertheless, this region has been suffering an accelerated process of degradation due to the agribusiness expansion. This study contributes to increasing knowledge on the Leptoceridae fauna of the Serra da Canastra Mountains at the Minas Gerais State, Brazil. Herein, we illustrate and describe two new species of Leptoceridae, Notalina franciscana sp. nov. and Oecetis catagua sp. nov., and provide additional data on the richness and distribution of Leptoceridae species in the Parque Nacional da Serra da Canastra and surrounding areas. Furthermore, ten species are firstly recorded from Minas Gerais State, increasing the number of Leptoceridae species recorded in the state from 30 to 42.
