SUMMARY

The preceding analysis of the amphibians and reptiles of the state of
Michoacan 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
Michoacan: _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 Michoacan 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 Michoacan: _Caiman crocodilus fuscus_, _Urosaurus
irregularis_, _Geophis nasalis_, _Tropidodipsas fasciata guerreroensis_,
and _Micrurus fitzingeri fitzingeri_.

Systematic studies based at least in part on specimens from Michoacan
have resulted in a redefinition of nine species and subspecies: _Bufo
marmoreus_, _Bufo perplexus_, _Anolis nebulosus_, _Anolis nebuloides_,
_Sceloporus bulleri_, _Sceloporus heterolepis_, _Sceloporus melanorhinus
calligaster_, _Hypsiglena torquata torquata_, and _Hypsiglena torquata
ochrorhyncha_.

Nine species that previously have been recognized as valid have been
placed in synonymy. These are: _Bufo horribilis_ Wiegmann, 1833, and
_Bufo angustipes_ Smith and Taylor, 1945, as synonyms of _Bufo marinus_
(Linnaeus), 1758. _Microbatrachylus albolabris_ Taylor, 1940,
