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.

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.

[2] The name of genus combines the Ancient Greek words herpō "to creep about" and lokhmē "thicket" or "copse".
