Zooplankton of an urban stretch, Itapecerica river, Divinópolis, Minas Gerais, Brazil

The aim of this project was to study the zooplanktonic composition of the Itapecerica river in its 29km urban section across the city of Divinópolis, state of Minas Gerais. Eight sampling points were established within this section, six in lotic and two in lentic waters. Samples were taken monthly from March/2002 to February/2003 totalizing 84 samples. A plankton net with a mesh opening size of 35 μm was utilized for sampling. Temperature, pH, dissolved oxygen and electrical conductivity measurements were also taken during sampling. 101 taxa were registered, of which 35 were Protozoa, 52 Rotifera, 10 Cladocera and four Copepoda. The number of taxa was considered high when compared to similar studies. Among the richest group, rotifers, the most expressed genera were Lecane and Brachionus. This study recorded the first appearance of the exotic species Kellicottia bostoniensis (Rousselet 1908) for the sub-basin of Itapecerica river

A new species of Smicridea McLachlan (Trichoptera:Hydropsychidae) from Venezuela and its role in travertine biogenesis

We collected an undescribed hydropsychid caddisfly, Smicridea (Smicridea) travertinera, n. sp., from 2 sites in Venezuela. One of the sites, Quebrada El Charo, flowed over extensive calcareous formations of travertine, which were covered with retreats and capture nets of the new species. Smicridea travertinera was the most abundant aquatic insect colonizing travertine.We describe the adult male, the retreat and net, and gut contents. The retreat consisted of an aperture in the travertine with a capture net. Retreat-making behavior appears to cause both the biogenesis and erosion of the travertine formations

Brazilian Trichoptera Checklist II

A second assessment of Brazilian Trichoptera species records is presented here. A total of 625 species were recorded for Brazil. This represents an increase of 65.34% new species recorded during the last decade. The Hydropsychidae (124 spp.), followed by the Hydroptilidae (102 spp.) and Polycentropodidae (97 spp.), are the families with the greatest richness recorded for Brazil. The knowledge on Trichoptera biodiversity in Brazil is geographically unequal. The majority of the species is recorded for the southeastern region

Checklist of butterflies (Insecta: Lepidoptera) from Serra do Intendente State Park - Minas Gerais, Brazil

In order to contribute to the butterflies’ biodiversity knowledge at Serra do Intendente State Park - Minas Gerais, a study based on collections using Van Someren-Rydon traps and active search was performed. In this study, a total of 395 butterflies were collected, of which 327 were identified to species or morphospecies. 263 specimens were collected by the traps and 64 were collected using entomological hand-nets; 43 genera and 60 species were collected and identified

Checklist of the Trichoptera (Insecta) of Brazil I

We present here a list of Trichoptera species recorded in the literature from Brazil as of September 2003. The total number of species recorded for Brazil is 378. The most diverse family is Hydropsychidae with 103 species; the second most diverse is Hydroptilidae with 50 species, followed by Leptoceridae and Philopotamidae with 41 each. Distributions by state and additional literature relevant to Brazilian Trichoptera are also presented

New distribution and species records of Trichoptera from Southern and Southeastern Brazil

We provide here a list of new species records of Trichoptera (Insecta) collected in Southern and Southeastern Brazil. We report 21 new distribution records for the country of Brazil. We also provide new distribution records for 92 species of Trichoptera for the states of Minas Gerais, São Paulo, Rio de Janeiro, Paraná and Santa Catarina
