Description
This species was not recorded in Singapore by earlier authors and is considered a new discovery in Singapore. Sinthusa nasaka amba resembles the Common Tit (Hypolycaena erylus teatus). However, it is much smaller in size and the markings on the undersides of the wings are slightly different from the Common Tit. The undersides of the forewings are shaded with orange.

The males are easily recognised, with the forewing an oily indigo blue and the hindwing shining blue. . It has a pair of thin threadlike tails which are white-tipped.
