Odonate Fauna of Rajasthan, India with Links to Arabia and Himalaya - Aquatic Ecosystem: Biodiversity, Ecology and Conservation - page 137

Conservation Status
IUCN Red List: Least Concern.

Habitat
Shallow lakes and ponds, where it keeps away from
the water's edge and perches on fl oating vegetation.

Remarks
Agriocnemis sania Nielsen, 1959, was made a
subspecies of A. pygmaea (Rambur 1942) by
Pinhey ( 1974 ). Dumont ( 1974 ) redescribed the
taxon and elaborated on the differences
between A. sania and A. pygmaea , the latter
being very abundant and widespread in Asia.
Though more taxonomic work is needed, both
species are currently considered as good spe-
cies, with A. sania occurring in north-eastern
Africa and A. pygmaea being widespread in
southern Asia (vide IUCN Red List of
Threatened Species).
Genus: Cercion Navas, 1907
(Subfamily: Coenagrioninae Kirby, 1890)

Conservation Status
IUCN Red List: Least Concern.

Threats
Habitat loss through human development of the
area.

Remarks
The placement of this species in Cercion is highly
doubtful. It has been treated both under
Coenagrion and Enallagma (original name);
however, there is little support for placing it in
either of these genera.
