New species of frog named after slaves
Measuring just 14mm, the new species has been name[d] Chiasmocleis quilombola after the quilombos communities typical of the Espírito Santo State in Brazil, where the frogs were collected.
Even today in the north of Espírito Santo State quilombola communities still remain and maintain alive their traditions, such as quilombola food and craftwork.
Chiasmocleis quilombola occupy coastal areas north of Espírito Santo State, a region that is under strong human pressure, therefore the species may face imminent threat of habitat loss.
The discovery was made by scientists from two US universities, the University of Richmond in Virginia and The George Washington University in Washington DC.
