Id help for Dacalana

[Psyche]

It is Dacalana cotys female.

Past discussion is flawed by the confusing images on the web.
The white markings are variable ? seasonal.


The two species can readily be separated thus.

Dacalana cotys.
FW postdiscal dark line midway between the termen(outer margin) and the white discal band.

The female D. penicilligera have the FW margin straighter as in the male but the postdiscal line is lunulate.
