Summary Falcaustra mackini (Walton, 1941) is redescribed. The anterior extremity is shown to be supported by three cordons arising from between the lips; the two subdorsal cordons are always curved on to the dorsal lip, whereas the ventral cordon curves on to either the right or left subventral lip. This cephalic morphology differs markedly from Falcaustra sensu stricto. F. mackini is designated type of Cordonema n. g. (Kathlaniinae). Cordonema cryptobranchi (Walton, 1930) n. comb. and C. variabilis (Walton, 1941) n. comb., both occurring in Cryptobranchus allegheniensis, the host for C. mackini, are included in the new genus. ac]19801207
