Rhyothemis plutonia

With the spotting of Rhyothemis plutonia, I've finally seen all the Rhyothemis species occuring in Peninsular Malaysia. There are six Rhyothemis species in Peninsular Malaysia namely R. triangularis, R. phyllis, R. aterrima, R. plutonia, R. obsolescens and R. pygmaea. Rhyothemis plutonia maybe confused with R. aterrima in Peninsular Malaysia. The presence of transparent (hyaline) forewing tips on R. plutonia may distinguish it from R. aterrima. However, the area of the transparent tip may vary in plutonia. Another good character to distinguish between aterrima and plutonia is the more extensive purplish green colour on the wings of plutonia .
