Genus Bayadera Selys, 1853 View in CoL

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.
