The 31 Indonesian members of the genus Saprosites REDTENBACHER are revised, including four species described as new: Saprosites mahavus n. sp. from Sulawesi, S. matangi n. sp. and S. penrisseni n. sp. from Borneo, and S. pahangensis n. sp. from Malay Peninsula. Lectotypes and paralectotypes are here designated for four species: Saprosites coelebicus PAULIAN, S. fruhstorferi PAULIAN, S. implicatus SCHMIDT and S. verecundus SCHMIDT. Seven new specific synonyms are proposed: Saprosites coelebicus PAULIAN (= S. jacobsoni PAULIAN, syn. n.), S. implicatus SCHMIDT (= S. sumatranus PETROVITZ syn. n.), S. japonicus WATERHOUSE (= S. imperfuscus SCHMIDT syn. n. and S. coomani PAULIAN syn. n.), S. mjoebergi GILLET (= S. fruhstorferi PAULIAN syn. n.), S. narae LEWIS (= S. tonkinensis BALTHASAR syn. n.), S. verecundus SCHMIDT (= S. malaisei PAULIAN syn. n.). A general diagnosis of the genus is associated with a key for identification based on principal morphological characters of 31 species. Habitus and male genitalia of several species are illustrated.
