Lake Hula Phantom Flutterer
(Rhyothemis semihyalina syriaca)

 
syn. -

 
distribution:

Israel: Hula Valley

 
local name: -

 
size: (?)

extinction date: sometimes after 1958

 
This species itself is distributed majorly in the tropical parts of Africa, the few populations outside this regions are throughout pleistocene relict populations, survivers of the ice ages. The population at the Lake Hula obviously seems to have evolved into a distinct subspecies.

About the taxonomic status of this subspecies however no real clarity seems to exist.

~~~~~~~~~~~~~~~~~~~~~

The complete drainage of the Lake Hula as well as of the swamps, associated with this lake, in the year 1958 led to the extinction not just only of this endemic dragonfly form.
