Heliogomphus nietneri

[sebbe67]

Not found since its description, more than 120 years ago. The species may already be extinct. It is not present in any of the large odonatological collections from the island made by entomologists over the last 50 years (NHM Basle (Switzerland); NMNH - Smithsonian Institution (USA); Lund University (Sweden); and University of Vienna (Austria)). Also, it was not found during the assessor's surveys in recent years (1995, 2001 and 2003).

I see. Thanks for the explanation... and the awsome picture.

This species was rediscovered in April 2005 by Nancy van der Poorten at two localities in the Knuckles range. It is a very rare species though and should be treated as Critically Endangered.
