Etymology and history of research

The Inca wren was first described in 1985 by Theodore Albert Parker III and John Patton O'Neill under the scientific name Thryothorus eisenmanni . The type specimen was collected by O'Neill on August 4, 1974 near San Luís near Cusco . As early as 1851, Jean Louis Cabanis introduced the genus Pheugopedius, which was new to science . This name is derived from "pheugō φευγω " for "avoid, flee" and "pedion, pedon πεδιον, πεδον " for "open land, ground". The species name "eisenmanni" is dedicated to Eugene Eisenmann .
