A survey of the Passalidae species recorded to the Ilha Grande (Angra dos Reis, Rio de Janeiro, Brazil) is presented, with illustrations for each species and a key with diagnosis for genera. Passalus (P.) denticollis Kaup, 1869 and Veturius (V.) transversus Dalman, 1817 was the relative abundance most dominate, representing almost 50% of relative abundance of species in each genus respectively. The study included material collected between January and December of 2008 and it results in 13 species included in four genera and two tribes (Passalini and Proculini). Passalini comprised ten species (Passalus, Spasalus and Paxillus), representing 71.42% of all species. Proculini with three species belong only Veturius, representing 28.57%. Among the 13 species, 12 are registered by first time from Ilha Grande. Veturius (Veturius) sinuatus was the unique species with distribution confirmed and Spasalus cristinae known only São Paulo had the distribution extended to Rio de Janeiro.
