Genus
Bayadera
Selys, 1853
The genus
Bayadera
consists of medium-sized stream-dwelling damselflies. They are characterized by wings petiolated to the level of the first antenodal crossvein and IR3 merging close to its base with the radius (
Davies & Yang 1996
). This genus is widely distributed across
India
,
Nepal
,
Japan
,
Taiwan
, southern
China
and Southeast Asia. A total of 17 species, presently ranked as valid, have been described (
Hämäläinen 2016
,
Schorr & Paulson 2017
).
Davies & Yang (1996)
described several species, including three new ones, from southern
China
and provided an identification key. Later,
Hämäläinen (2004)
showed the variation of wing pattern of
Bayadera melanopteryx
Ris,
1912
in
China
and elevated three subspecies of
B. brevicauda
Fraser, 1928
to distinct good species:
B. brevicauda
Fraser, 1928
,
B. ishigakiana
Asahina, 1964
, and
B. continentalis
Asahina, 1973
, with a discussion on their morphological characteristics. Recently two more species were described:
Bayadera kinnara
Hämäläinen, 2013
from
Myanmar
(
Burma
) and
B. hatvan
Hämäläinen & Kompier, 2015
from northern
Vietnam
(Hämäläinen 2013,
Hämäläinen & Kompier 2015
, respectively). From
Vietnam
, seven species have now been confirmed, of which three are recorded for the first time in this paper. Female of
Bayadera serrata
is described for the first time.
