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 cylindrical instead of tapered from base to end and reddish yellow instead of blood red.
