Lyriothemis acigastra is a species of dragonfly in the family Libellulidae, found in India. Until 2013, it was thought to be restricted to the northeastern states of Assam and West Bengal, but it has now also been recorded in the southern state of Kerala. It is a small dragonfly with brown-capped greenish-yellow eyes and a blackish-brown thorax marked with yellow. Laterally, there are three stripes. Its wings are transparent, palely tinted with yellow at the base. The female is similar to the male, but the abdomen is cylindrical instead of tapered from base to end and reddish yellow instead of blood red. This picture shows a male L. acigastra individual.Photograph credit: Jeevan Jose
