Taxonomy

The Choco sirystes was formally described in 1863 by the American amateur ornithologist George Newbold Lawrence under the binomial name Lipaugus albogriseus.^[2] The specific epithet combines the Latin albus with the Medieval Latin griseum meaning "grey".^[3] Lawrence did not mention a type locality but Osbert Salvin and Frederick DuCane Godman, in their book Biologia Centrali-Americana, reported that the specimen had come from "Lion Hill".^[4] This was a railway station in the Panama Canal Zone that was submerged when the Gatun Lake was created.^[5] The Choco sirystes is now one of four species placed in the genus Sirystes that was introduced in 1860 by the German ornithologists Jean Cabanis and Ferdinand Heine.^[6]
