(Thamnophilidae; Ϯ Black-and-white Antbird M. hemileucus) Gr. μυρμος murmos ant; χαινω khainō to gape greedily; "Myrmochanes, gen. nov. Bill long, depressed, broad at base, becoming rapidly narrower and attenuate, commissure slightly arched; nostrils open, linear oval; wings rounded, fourth, fifth, and sixth primaries longest and subequal; tail short, graduated, about three-fifths as long as ther wing; tarsus long, distinctly scutelate behind as well as in front. Type, Myrmochanes hypoleucus, sp. nov. The bird on which the present species is based is about as large as an average sized species of Formiccivora [sic] or Myrmotherula, with, however, a very much larger and more flattened bill, and very much longer and heavier tarsi and feet. Its position in the family is apparently near Pyriglena." (J. A. Allen 1889); "Myrmochanes J. A. Allen, Bull. Am. Mus. Nat. Hist., 2, 1889, p. 95. Type, by original designation, Myrmochanes hypoleucus = Hypocnemis hemileuca Sclater and Salvin." (Peters 1951, VII, 227).
