This work provides three new photographic records and evidence of increase in distribution of Heloderma alvarezi based on different encounters between human activities and the displacement of this species along the central coast of Oaxaca, Mexico.  Until now, this species occurred only in Chiapas State, however, the new records provide information about the increase in species distribution on the coast of Oaxaca, so this has increased the number of reptiles in Oaxaca to 448 species.
