The northern plain xenops (Xenops mexicanus) is a passerine bird in the Furnariinae subfamily of the ovenbird family Furnariidae. It is found from southern Mexico through Panama to northern Colombia, northwest Venezuela and western Ecuador. It was formerly considered as conspecific with the Amazonian plain xenops.
Taxonomy
[edit]The northern plain xenops was formally described in 1857 by the English zoologist Philip Sclater based on specimens collected near Córdoba in southern Mexico by Auguste Sallé. Sclater coined the binomial name Xenops mexicanus.[1][2] The northern plain xenops is now one of five species placed in the genus Xenops that was introduced in 1811 by Johann Illiger. It was formerly considered as conspecific with the Amazonian plain xenops. The two species were split based on differences in plumage, vocalizations and DNA sequence.[3][4]
Five subspecies are recognised:[3]
- X. m. mexicanus Sclater, PL, 1857 – south Mexico to Honduras
- X. m. ridgwayi Hartert, EJO & Goodson, 1917 – Nicaragua to central Panama
- X. m. littoralis Sclater, PL, 1862 – east Panama and north Colombia to west Colombia, west Ecuador and northwest Peru
- X. m. olivaceus Aveledo & Pons, 1952 – northeast Colombia
- X. m. neglectus Todd, 1913 – northeast Colombia and north Venezuela
