To complete the quartet.

Nacaduba beroe neon.

Male with the dark striae weak to obsolete.
FW postdiscal band typically broken or dislocated.
Male upperside deeper purple blue than in calauria.

Female; This female have a vague mark like a third costal spot but the upperside (shown by Sunny) is darkish blue with blue FW submarginal spots.

Ionolyce helicon . Very common & often confused with N. beroe.
FW innermost costal spot absent (as in N. beroe.)
FW postdiscal band irregular & often serially dislocated at each vein.
HW submarginal spots chevrons (V-shaped) rather than lunulate (lunar shape)
Males.
Typical.

Looking more like N. beroe.. 2nd pic possibly hybrid., like beroe but HW submarginal spots pointed. Correction: N. beroe based on FW postdiscal band being barely dislocated at vein 4 & rounded HW.

Possibly with hybrid blood. Correction : Female N. beroe variant; HW shape is totally wrong for I. helicon female, & FW postdiscal band can be undulate in female beroe.
