Macroinvertebrates in a high Andean wetland (Chalhuanca) of southern Peru during the dry and wet season

Abstract

Macroinvertebrates of the Chalhuanca high Andean wetland (bofedal) is presented, which presents two aquatic environments, river and water pools within bofedal vegetation. This wetland is located in the district of Yanque (Caylloma, Arequipa) at 4300 meters, in southern Peru. Aquatic macroinvertebrates in wetlands such as these have been sparsely studied in Peru and other localities, especially in the southern region, which is added to their taxonomic complexity for identification. For this bofedal 32 families were identified, distributed in 21 orders and 12 classes. The richest groups were Diptera, Coleoptera, Trichoptera and Anomopoda. The other groups presented only one family. By type of environment, 25 families were registered for bofedal and 26 for the river, where exclusive families were presented for found environments 05 exclusive families of bofedal (Chydoridae, Coenagrionidae, Ilyocryptidae, Lumbriculidae, Dytiscidae), and 05 exclusive families of river (Gripopterygidae, Hydrobiosidae, Hydrophilidae, Leptoceridae, Saldidae).
