Systematics, distributions, and bionomics of the Neoeocatops gen. nov. and Nemadus of North America (Coleoptera: Leiodidae: Cholevinae: Anemadini)

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.

Colydiidae (Coleoptera) in the Maritime Provinces of Canada and Maine in the United States

Abstract The beetle family Colydiidae in the Maritime Provinces of Canada and in Maine in the United States is surveyed. Two species, Lasconotus borealis Horn and Synchita fuliginosa Melsheimer, are newly recorded from Nova Scotia. Records of L. borealis in New Brunswick are also reported, as are those of S. fuliginosa from Maine. The distribution and bionomics of both species are discussed. The fauna is briefly evaluated in the context of saproxylic beetles in general, and in particular in relation to the impact of forest management practices on such species. The possibility of Colydiidae occurring on Prince Edward Island is briefly discussed.
