Abstract

Two new genera of Trechaleidae are described and illustrated. Amapalea gen. n., type species A. brasiliana sp. n., from Amapá, and Magnichela gen. n., type species M. santeremensis from Pará, both states located in Northern Brazil region. Amapalea presents a tegular projection not found in any other Trechaleidae genera, like Paratrechalea Carico, 2005 and Paradossenus F.O.P.-Cambridge, 1903. Magnichela gen. n. can be distinguished from the other genera and from Amapalea gen. n., by the enlarged and apically expanded chelicerae.
