The genus Cercophonius Peters is revised, and generic and specific diagnosis are updated. By means of the study of specimens from different localities and the type material, four species (C. michaelseni Kraepelin, C. sulcatus Kraepelin, C. granulosus Kraepelin and C. kershawi Glauert), formerly synonymyzed with the type species C. squama (Gervais), are hereby reinstated as valid; a sixth, new species, C. queenslandae is described. The diagnostic characters used at specific level are: development of ventral carinae in caudal segments I to IV and sternite V; morphology of the hemispermatophore, and pigmentary patterns of tergites and metasoma; other characters, such as the number of pectinal teeth, total lenght and the shape of telson show some differences useful to the determination, although not permiting a clear separation of the species. A key for the species, as well as a discussion on the taxonomic relationships of Cercophonius with Urophonius Pocock and Phoniocercus Pocock (its two closest relatives) are added. A map of the known localities of Cercophonius is also included.
