Abstract

Aulacopleurid trilobites of the Malvinokaffric Realm (Lower and Middle Devonian) of South America and South Africa include seven species (of which six are formally named) assigned to two genera. These include a distinct subclade of the otarionine Maurotarion ALBERTI, 1969, and at least two species of Malimanaspis BALDIS & LONGOBUCCO, 1977, a genusof problematic affinities. Malimanaspis is considered a subjective senior synonym of Goodsiraspis ADRAIN & CHATTERTON, 1993. Malvinokaffricaulacopleurid diversity includes two separate invasions of cosmopolitan taxa with long independant histories and obvious close comparisons among species from the lower latitudes. New Bolivian species include Maurotarion isaacsoni (Lower Devonian, Gamoneda Formation), M. racheboeufi (Emsian, Icla Formation), and M. legrandi (Eifelian, Belen Formation). One additional new species of Maurotarion is reported in open nomenclature. The specific concept of Maurotarion ion dereimsi (KOZLOWSKI, 1923), to which almost all South American aulacopleurids have at times been referred, is restricted to late Lochkovian or earliest Pragianmaterial, very likely from the lower member of the Icla Formation, Chuquisaca Department, Bolivia. Malimanaspis angustilimbata PEK & VANEK,1991, is revised on the basis of new material.
