Nineteen new species of the genus Ochrotrichia Mosely from Mexico and Central America are described and the male genitalia figured: O. ixcateopana (Mexico); O. crucecita (Panama); O. arriba (Panama); O. zihuaquia (Mexico); O. blanca (Belize); O. maycoba (Mexico); O. eyipantla (Mexico); O. glabra (Panama); O. hondurenia (Belize); O. corneolus (Panama); O. anomala (Panama); O. bicaudata (Panama); O. regina (Panama); O. lupita (Panama); O. maya (Mexico); O. palmata (Mexico); O. serrana (Mexico); O. poblana (Mexico); and O. velascoi (Mexico). This genus has a wide distribution, from southern Canada south throughout Mexico and Central America, the West Indies, and South America. Key Words: taxonomy, Ochrotrichia, Trichoptera, Hydroptilidae, Mexico, Central Amer- ica The genus Ochrotrichia Mosely of the on the foreleg, the abdomen often possesses Neotropical Region has been studied by internal sacs and/or setal brushes, and the Mosely (1937), Denning and Blickle male genitalia has the tenth tergum reduced (1972), Bueno and Santiago (1981, 1992) to a simple membranous lobe, a button-like and Flint (1972). However, in Mexico, Cen- cercus, dorsolateral hooks, and a very large tral, and South America there are still many phallus, usually with two large hooks. undescribed species. Most of the species of Ochrotrichia here This genus was previously divided into described, were provided by Dr. Oliver S. the subgenera Ochrotrichia and Metrichia Flint, Jr. from the collection of the National by Flint (1972) because of his belief that Museum of Natural History (NMNH) the larvae of both genera were indistin- where they will be deposited.

Metrichia has an apical spur (Marshall 1979).
