Scientific Name: Archibasis rebeccae
Common Name: Rebecca’s Sprite
Archibasis rebeccae is a very rare damselfly species that has been recorded only once in Singapore in the Central Catchment Nature Reserve on 2009. This species appears to be endemic to Peninsular Malaysia and Singapore. It occurs in lowland primary forests and streams.
This individual was taken on a trip to MacRitchie Reservoir’s forest in 2013. It was found along a quiet trail along Sime forest.
Male of this species are lighter blue. The appearance is very similar to A. melanocyana, and A. incisura. Segments 8 and 9 of the abdomen are blue. There are tiny blue spots on the dorsum of segment 10 of the abdomen. The superior appendages are strongly clubbed.
There is an interesting article about this species by Robin Ngiam.
It is frustratingly difficult to identify this species of damselfly. I hope my Id is correct.
