Two new genera and nine new species of damselflies from a localized area in Minas Gerais, Brazil (Odonata: Zygoptera)

Abstract

Two new genera, Franciscobasis and Franciscagrion, and seven new species, i.e. Acanthagrion franciscoi, Franciscobasis franciscoi, Franciscobasis sonia, Franciscagrion franciscoi, Franciscagrion longispinum, Minagrion franciscoi and Oxyagrion franciscoi, are described and illustrated. In addition, two new species of Peristicta are reported and will be described elsewhere. All these species have been collected along a 600 m stretch of the headwaters of the São Francisco River, within the Serra da Canastra National Park, in the state of Minas Gerais, Brazil. The significance of this finding in such a small area is discussed.
