The butterfly occurs in India in the Western Ghats, Nilgiris and the Palni hills.
A record in Calcutta may be vagrant or mistaken.
The butterfly has a wingspan of 45 to 50 mm. The butterflies resemble the common spotted flat except that the discal spot in 2 and the spot end cell of the forewing are separate. The upper hindwing is only obscurely marked. The antenna is chequered and has a white club.
It is common along the Western Ghats, especially during the monsoon. It may be caught in the daytime by beating out roadside patches of Lantana camara.
Food plants: Phaulopsis, Strobilanthes (Acanthaceae).
