The Trichoptera of Panama XXI. Review of the genus Tizatetrichia Harris, Flint, and Holzenthal, 2002 (Trichoptera: Hydroptilidae), including two new species, one first country record, and female description of T. panamensis Harris and Armitage, 2019

Abstract

The genus Tizatetrichia Harris, Flint, and Holzenthal, 2002 (Trichoptera: Hydroptilidae) was described based on a single male of T. costatricensis Harris, Flint, and Holzenthal, 2002 collected from Guanacaste Province in northwestern Costa Rica. Since then, the second species (T. panamensis Harris and Armitage, 2019) was discovered in a small Caribbean drainage near Chiriquí Grande, Panama. No female of this genus had been described. Recent collections carried out by the Aquatic Invertebrate Research Group (AIRG) at the Universidad Autónoma de Chiriquí (UNACHI) now expand our knowledge of this genus. Herein, we describe a female of Tizatetrichia for the first time, comparing it with that of the related genus Bredinia Flint, 1968. In addition, we describe two new species from central and western Panama (T. escabrosa sp. n. and T. paloseco sp. n.), report one first country record (T. costaricensis), provide keys to the identification of Stactobiinae genera and Tizatetrichia species, and discuss the distribution of the genus in relation to altitude. Panama is now the home to all four species of this Neotropical genus, and its endemic status expanded to Central America. The Republic of Panama has 490 species of caddisflies distributed among 15 families and 56 genera.
