Ananteris duponti Ythier & Lourenco, 2026

The article has am identification key for the Ananteris species in French Guiana. 

The biogeography of the family and the genus is discussed.

Abstract:
One new species belonging to the genus Ananteris Thorell is described from the foot of the Mount Grand Matoury, French Guiana. The description of this new species brings further evidence about the biogeographic patterns of distribution presented by most species of the genus Ananteris, which are highly endemic in many natural formations of South America and in particular in French Guiana. The new taxon described here raises the number of known species for the genus Ananteris in French Guiana to 13, and the total number of currently recognized species for the genus to 100. A geographical distribution map of the species occurring in French Guiana is presented and an identification key is proposed.
