Resumen Introducción: La Familia Chironomidae es reconocida por su gran abundancia y diversidad en los ecosistemas de agua dulce alrededor del mundo. Sin embargo, el conocimiento taxonómico de esta familia es limitado, particularmente en Colombia. Objetivos: Estimar la abundancia y diversidad a niv...
Introducción: Los quironómidos forman parte de los macroinvertebrados esenciales en la tipificación de hábitats acuáticos, ya que albergan especies sensibles a la contaminación, mientras que otras son indicadoras de ambientes bien conservados. Son organismos claves por su abundancia, diversidad, y ...

In Northern Tunisia, seasonal streams, called wadi, are characterized by extreme hydrological and thermal conditions. These freshwater systems have very particular features as a result of their strong irregularity of flow due to limited precipitation runoff regime, leading to strong seasonal hydrologic f...
Introduction: Chironomids (Diptera: Chironomidae) are the most globally diverse and widely distributed aquatic insects. Despite their prevalence in lotic systems, little is known about the ecology and diversity of tropical species relative to other aquatic insect taxa, particularly at the immature stages...
Denopelopia amicitia Dantas, Hamada & Mendes foi descrita com base no macho e na pupa coletados na Amazônia brasileira. Aqui descrevemos e ilustramos a fêmea e a larva desta espécie. Em ambos os estágios, D. amicitia é similar à Denopelopia atria Roback & Rutter, que é a única espécie do gênero...
Abstract The management and use of native species under laboratory conditions is the main difficult for species proposal for its use in bioassays. The present study showed the results about management under controlled conditions of Paratanytarsus grimmii (Diptera: Chironomidae), that is a parthenogenetic...
Abalesmyia cordeiroi Neubern was originally described based on adult males collected in the Amazon region; therefore, females and immatures of this species are unknown. In the present study, the pupal and larval stages of A. cordeiroi are described and illustrated. In addition, an amendment to the larval...
Abstract The family Chironomidae (Diptera) is the most widely distributed, most diverse, and often the most abundant of all families of benthic macroinvertebrates in aquatic ecosystems, including estuaries and other coastal marine ecosystems. Chironomid assemblages are likely to provide a useful measure ...
Abstract A new species of gall midge that induces stem galls on Aeschynomene denticulata (Fabaceae) is described based on material collected in Pantanal (Mato Grosso do Sul, Brazil). This species is unique among the Brazilian congeners in having spatula with three convex teeth, cruciate, with defined ant...
Abstract Biomonitoring is a cheap and effective tool for evaluation of water quality, and infer on the balance of aquatic ecosystems. The benthic macroinvertebrates are bioindicators sensitive to environmental changes, and can assist in detecting and preventing impacts such as organic enrichment and imba...
