Group outings to Mahua Waterfall, Tambunan in Sabah (9-15 February 2020)

The Tanaecia iapis complex is quite complicated in Borneo.
There are numerous forms which are either as ssp or forms.


Many authors now separated the type in Java as a different species.
eg T iapis iapis .
Male & female , Java.

The representatives from Sumatra, Malay & Borneo are referred to T. cocytina.
Further, some placed them under the genus Cynitia.

Although there are numerous named ssp. in Borneo the one in Sabah is generally ssp ambalika.

This form is named as taxon diardi but usually placed under ambalika.
See Tanaecia cocytina ambalika in funet.
