Very difficult to ID small lycaenid from the underside with the FW down.
There is no submarginal spot (lunule).
This narrow it down to 3 species.
See Borneo Lycaenidae . L88, L89, & L90.

L89. U. dilectissima can be ruled out because the two HW postdiscal spots 6 & 7 are equal.

This means it is either U. camenae or selma.
General appearance suggest U. selma but U. camenae is probably the commoner species.


2. Eurema ada.
FW with 2 cell spots; termen (margin) rounded.
HW postdiscal spot 7 a long sinuous streak.
