As far as I know, the Central american red brocket (Mazama temama) actually used to be considered a subspecies of Mazama americana, but it turns out that Mazama temama has subspecies of its own, there are 3 recognized subspecies and they are listed below
Mazama temama temama
Mazama temama cerasina
and
Mazama temama reperticia
However I don't have any specific details regarding the differences between the those subspecies (morphological, genetic, coloration etc). If anybody happens to have more information about that, I would be interested in hearing what you have to say.
In regards to the geographic ranges of those taxa, correct me if I am wrong or let me know if I am not explaining it in enough detail, but I believe Mazama temama cerasina is native to Costa Rica, El Salvador, Guatemala, Honduras, and Nicaragua. Mazama temama reperticia is native to Panama and Colombia, and the nominate subspecies Mazama temama temama is native to Mexico
@carlos55, out of curiosity would you by any chance happen to know how and where San Juan De Aragon Zoo sourced those animals or how long the zoo has been keeping them?
The mexico city zoos, chapultepec and san juan de aragon have had brocket deers since about 1994. The first mexican zoo to breed brocket deers was zoomat, zoologico miguel alvarez del toro, in the state of chiapas. Zoomat has bred brockets since 1980. I would suppose that the mexico city brockets had come from zoomat and were more habituated to capitivity. Currently various mexican zoos breed brockets. Africam safari park in Puebla sent brockets to phoenix zoo, where they have done quite well.
