Rio de Janeiro Damselfly (Fluminagrion taxaense)  

The Rio de Janeiro Damselfly is known only from its type locality, which is now obviously a part of a urban park within the city of Rio de Janeiro in the same-named state of Rio de Janeiro in Brazil.  

The species was described in 1965, since then, however, it was never recorded again and is considered most probably extinct.  

***

The species was formerly doubtfully assigned to the genus Acanthagrion but is now placed in its own genus. [1]
