English abstract The characters defining Mecosarthron Buquet, 1840 and Xixuthrus Thomson 1864 are discussed, along with a historical review of the literature that described and classified these taxa. Through morphological examination of these genera and most of the included species, we addressed the systematic placement of Xixuthrus domingoensis Fisher, 1932 that was placed in Mecosarthron by Ivie (1985). We restore its placement in the genus Xixuthrus. The first description of the female of X. domingoensis is provided, along with comparative redescriptions of Mecosarthron gounellei (Lameere, 1903), and M. buphagus Buquet, 1840. We include a key to the species currently in Mecosarthron
Portuguese abstract Os caracteres que definem Mecosarthron Buquet 1840 e Xixuthrus Thomson 1864 são discutidos, juntamente com uma revisão histórica da literatura que descreveu e classificou esses táxons. Com base no exame morfológico desses gêneros e da maioria das espécies incluídas, Xixuthrus domingoensis Fisher 1932, que havia sido transferido para Mecosarthron por Ivie (1985), foi restaurado em sua combinação original. Apresentamos a primeira descrição das fêmeas de X. domingoensis, juntamente com redescrições comparativas de Mecosarthron gounellei (Lameere, 1903), e M. buphagus Buquet (1840). Incluímos uma chave para as espécies de Mecosarthron
