- Abstract
The new species Oropogon evernicus Essl. & S. Leavitt and O. protocetraricus S. Leavitt & Essl. are described from montane regions of Central America, further increasing the diversity of this genus in the New World. Oropogon evernicus is separated from O. americanus by the presence of medullary tissue directly beneath the pseudocyphellae, while O. protocetraricus is separated from O. caespitosus by the presence of protocetraric acid. The segregation of both species is confirmed by molecular sequence data (nuclear ITS, nuLSU, and β-tubulin). Both species appear to have split from their most recent common ancestor during the Miocene, supporting Miocene-dominated diversification of neotropical Oropogon species found in Central America.
