Metaleptobasis gibbosa Tennessen

Gibbose Forest Damselfly (Metaleptobasis gibbosa)

The Gibbose Forest Damselfly was described in 2012 based on specimens that had been collected in 2005; the species has only ever been found in a very small area, a forest wetland in Los Copales in the Pastaza Province of Ecuador.

The species reaches a length of about 4,6 cm; it is quite inconspicuous colored, the eyes are red-orange dorsally and green anteriorly, the thorax is generally brown-orange with darker brown medially stripes, the abdomen is mostly grey-brown.

The only known locality was destroyed in 2012 for the development of houses; the species has not been found anywhere else, despite searches.

Megalagrion nesiotes (Perkins)

Red Hawaiian Damselfly (Megalagrion nesiotes)

The Red Hawaiian Damselfly was described in 1899, it is or rather was endemic to Hawai’i, Hawaiian Islands.

The biology of this species appears to be completely unknown, it is considered extinct.

The Red Hawaiian Damselfly was formerly synonymized with another species from the island of Maui, The Black Maui Damselfly (Megalagrion dinesiotes Kennedy), a species that was thought to be extinct for some time but which was rediscovered. [1][2]

Fluminagrion taxaense (Santos)

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]
