Great efforts have been done to collect germplasm of theArachisgenus in South America, however, many regions still remain underexplored. Under the hypothesis that these regions have new and diverse populations/species ofArachis, several expeditions were carried out since 2000 in Bolivia, to increase the documentation of the genus diversity. As a first result of these explorations, a new species of sectionArachiswith B genome is formally described.Arachis inflatais closely related toA. magnaandA. ipaënsis, but it can be clearly distinguished from them, and from any other species of the genus, for having a type of fruit with a completely distinct morphology. The fruit has a smooth epicarp, but shows a bullated aspect, due to the presence of air chambers in the mesocarp.
