Herpsilochmus

Herpsilochmus is a genus of insectivorous passerine birds in the antbird family (Thamnophilidae). They are found in forest, woodland and shrub in South America, although a single species the rufous-winged antwren (H. rufimarginatus) also occurs in Panama. All are relatively small antbirds that are sexually dichromatic. In most (but not all) species males are essentially light grey with a black crown and black-and-white wings, while females are more buff or rufous with black-and-white crown.

The genus Herpsilochmus was introduced by the German ornithologist Jean Cabanis in 1847. The name of genus combines the Ancient Greek words herpō "to creep about" and lokhmē "thicket" or "copse". The type species is the Bahia antwren.
