This species comes near to L. pavana and L. plato. It is a 

 deeper purple blue in colour. It has fewer markings on the under 

 surface of wings than L. pavana. The markings are silvery grey, 

 and the colour of the under surface generally is a slaty grey in 

 L. oranigra, but in L. plato the markings are whiter and the 

 colour of the under surface more creamy. The under surface of the 

 knob or club of antenna is white, tipped with black in oranigra, 

 with orange in L. plato, and with white in L. pavana. The 

 deep black border is at once a conspicuous distinction.
