Abstract
Three new species of Triplonychus Candeze, T. cruspinosus sp. nov., T. crassifemovis sp. nov. and T. tibialatus sp. nov., and a new species of Globothorax Fleutiaux, G. latidens sp. nov., from Brazil are described. Illustrations, photographic and SEMimages are presented. A review of the diagnostic generic characters and a key to the species of Triplonychus and Globothorax from Brazil are also given. The genus Triplonychus was erected by Candeze (1860) to include ten species from South America basedon a combination of several non exclusive characters among which he emphasized the incomplete lateral carina of pro-thorax, the carinate ninth elytral interstice, the elongate antenna and the elytral and prothoracic shapes. He also cited two characters found exclusive to this genus: the tricuspid claws and the elytral striae with two or more rows of punctures.
