First report of Simuliidae and Chironomidae (Diptera) living on nymphs of Lachlania Hagen (Ephemeroptera: Oligoneuriidae) in South America

We report cases of Simuliidae and Chironomidae living on Lachlania nymphs (Ephemeroptera). This is the first record of these associations in South America. Simulium exiguum (pupae and larvae), Simulium cuasiexiguum (larvae), Cricotopus sp. (larva) and Rheotanytarsus sp. (larva) were found associated...

Zusammenfassung:We report cases of Simuliidae and Chironomidae living on Lachlania nymphs (Ephemeroptera). This is the first record of these associations in South America. Simulium exiguum (pupae and larvae), Simulium cuasiexiguum (larvae), Cricotopus sp. (larva) and Rheotanytarsus sp. (larva) were found associated with Lachlania nymphs. We believe that all of these associations can be classified as opportunistic (or casual) attachment. Este é o primeiro registro de associações entre imaturos de Simuliidae e Chironomidae vivendo sobre ninfas do gênero Lachlania (Ephemeroptera) na América do Sul. Simulium exiguum (pupas e larvas), Simulium cuasiexiguum (larvas), Cricotopus sp. (larva) and Rheotanytarsus sp. (larva) foram coletadas vivendo sobre/aderidas a ninfas de Lachlania. Apesar de existirem algumas espécies que vivem, obrigatoriamente, sobre ninfas e larvas de outros insetos aquáticos, no presente estudo estas associações podem ser classificadas como casuais.
