Larval and female descriptions of Mejicanotrichia Harris & Holzenthal, 1997 (Trichoptera, Hydroptilidae, Leucotrichiinae) from Mexico

Abstract

Mejicanotrichia Harris & Holzenthal, 1997 is a small genus of Hydroptilidae (Trichoptera), which consists of seven species, six of them distributed in Mexico, and one more in Guatemala. Larval descriptions of only two species (M. blantoni and M. estaquillosa) were previously known, as well as only females of three species (M. blantoni, M. estaquillosa, and M. tamaza) previously described. The present study provides descriptions of the larvae of M. harrisi and M. tridentata, as well as a description of the female of M. harrisi. Identification keys for adult males, known females, and known larvae are also provided. This work aims to incorporate more information into the taxonomy of the genus, its ecology, and facilitate additional characters of potential use in future phylogenetic studies.
