Name
Sinhalestes Fraser, 1951

Sinhalestes orientalis, the emerald Sri Lanka spreadwing, is a monotypic species of damselfly in the family Lestidae. The species was thought to be extinct since none have been found since it was first scientifically described in 1862. However, in 2012 this species was re-discovered by a young odonatologist Amila Sumanapala from the Peak Wilderness Sanctuary, Sri Lanka.

It is endemic to Sri Lanka and so far it has only been recorded from Peak Wilderness Sanctuary and its surrounding areas.
