Lyriothemis flava
Lyriothemis flava is a species of dragonfly in the family Libellulidae. It is found in Bangladesh, China, India, Japan, Myanmar, and Taiwan.
In India, Lyriothemis species were thought to be restricted to the northeastern states like Assam and West Bengal; but, in 2013, L. acigastra and L. flava were recorded in the southern state of Kerala. The recent study concluded that the species previously misidentified as L. flava in Kerala was of the newly described species Lyriothemis abrahami.
