The antbird family contains over 200 species, variously called antwrens, antvireos, antbirds and antshrikes. The names refer to the relative sizes of the birds (increasing in the order given, though with exceptions) rather than any particular resemblance to the true wrens, vireos or shrikes. In addition, members of the genus Phlegopsis are known as bare-eyes, Pyriglena as fire-eyes and Neoctantes and Clytoctantes as bushbirds. Although the systematics of the Thamnophilidae is based on studies from the mid-19th century, when fewer than half the present species were known, comparison of the myoglobin intron 2, GAPDH intron 11 and the mtDNA cytochrome b DNA sequences has largely confirmed it.[4] There are two major clades most antshrikes and other larger, strong-billed species as well as Herpsilochmus, versus the classical antwrens and other more slender, longer-billed species and the monophyly of most genera was confirmed.
