Is this Eurema ada iona (Talbot's Grass Yellow); appears to have only one spot near the basal wing margin of forewing. Thanks in advance for confirmation

I realised the above explanation is rather confusing.
Simply put, if the forewing has only one cellspot( the black spot lower down), it can only be E. andersoni or lacteola.
(E. ada has two forewing cellspots).

The strong greenish yellow colour & the clear forewing apex indicate it is E. lacteola.

The forewingshape is distorted so the alignment of the black border is difficult to judge.

TL Seow:Cherers.
