The Order Trichoptera in Tucumán, Argentina : new record of Leucotrichia lerma (Angrisano y Burgos, 2002) (Trichoptera: Hydroptilidae), description of its immature stages, list of species and illustrated identification keys

Abstract

Leucotrichia lerma Angrisano y Burgos (2002) is recorded for the first time in a river from Tucumán province. Its imma- ture stages were associated using the methamorphotype method. A species list is included for the province and for the first time we present illustrated identification keys of Tri- choptera larvae at different taxonomic levels. Fifty one species of Trichoptera, assigned to 12 families and 24 genera, are recorded from Tucumán province. Only 25 species were associated to species level. These are included in a specific key.
