Peck,1 Joyce Cook Department of Biology, Carleton University, Ottawa, Ontario, Canada K1S 5B6 Abstract—This paper completes a review and revision of the tribe Anemadini in North Amer- ica, 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 con- taining 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. Résumé—Ce travail complète une revue et une révision de la tribu Anemadini (Coleoptera : Leiodidae : Cholevinae) d’Amérique du Nord; il traite de la sous-tribu Eocatopina (nouvelle pour l’Amérique du Nord) qui contient le genre Neoeocatops gen. nov. avec une espèce et de la sous- tribu Nemadina qui comprend le genre Nemadus Thomson, 1867 avec 12 espèces. Ces espèces vivent dans les forêts et se nourrissent de charogne et d’autres matériaux en décomposition; elles peuvent aussi se retrouver dans les cavernes ou alors être des myrmécophiles vivant dans les nids de fourmis formicinées, surtout des genres Formica L. et Camponotus Mayr. Nous établissons les nouvelles synonymies suivantes : N. ellipticus Jeannel, 1936 = N. horni Hatch, 1933 et N. obli- quus Fall = N. triangulum Jeannel, 1936. Nous désignons des lectotypes pour Catops brachyde- rus LeConte, 1863, Catops pusio LeConte, 1859 et Choleva decipiens Horn, 1880. Les nouvelles espèces sont Nemadus browni Peck et Cook, sp. nov., N. criddlei Peck et Cook, sp. nov. et N. falli Peck et Cook, sp. nov.
