You do have Drupadia niasica.

1st is the size difference .D. theda FW >14mm (C&P4) 17-20mm (Fleming). D. niasica 11.5-13 mm (C&P4) , 12-14mm (Fleming)

2nd Doherty described the type specimen of scudderi which he states the tail is chiefly black except at the tip; underside much as in thesmia (D. theda).

3rd. IN C&P4 page 303 the key states the female niasica has the underside apical area browner than theda .


Your 2nd pic is obviously a female, & so has to be D. niasica.


I presume from the location it is ssp. biranta.


TL Seow: Cheers.
