This paper completes a review and revision of the tribe Anemadini in North America, covering the subtribe Eocatopina (new for North America), with the genus Neoeocatops gen. nov. containing one species, and the subtribe Nemadina, with the genus Nemadus Thomson containing 12 species. Species are forest inhabitants feeding on carrion and other decaying materials, may occur in caves, or are myrmecophiles occupying the nests of formicine ants, mostly of the genera Formica L. and Camponotus Mayr. The following new synonyms are recognized: N. ellipticus Jeannel, 1936 = N. horni Hatch, 1933 and N. obliquus Fall, 1937 = N. triangulum Jeannel, 1936. Lectotypes are designated for Catops brachyderus LeConte, 1863, Catops pusio LeConte, 1859, and Choleva decipiens Horn, 1880. New species are Nemadus browni Peck and Cook, sp. nov., N. criddlei Peck and Cook, sp. nov., and N. falli Peck and Cook, sp. nov.
