SUMMARY The preceding analysis of the amphibians and reptiles of the state of Michoacán shows that the herpetofauna is composed of 176 species and subspecies definitely recorded from the state, plus ten others that probably occur there. Ten species are reported for the first time from Michoacán: _Pseudoeurycea robertsi_, _Leptodactylus occidentalis_, _Microbatrachylus pygmaeus_, _Pternohyla fodiens_, _Hypopachus caprimimus_, _Phyllodactylus homolepidurus_, _Anolis dunni_, _Sceloporus bulleri_, _Sceloporus heterolepis,_ and _Geagras redimitus_. Five species that have been reported previously from Michoacán are based on specimens having unreliable locality data or on misidentifications; therefore, the following species are not considered to be a part of the herpetofauna of Michoacán: _Caiman crocodilus fuscus_, _Urosaurus irregularis_, _Geophis nasalis_, _Tropidodipsas fasciata guerreroensis_, and _Micrurus fitzingeri fitzingeri_.
