Delias ganymedes Okumoto 1981 
Subspecies and range of Delias ganymedes :
. ganymedes Okumoto 1981 - Mt. Canlaon, Negros Island
. filarorum Nihira & Kawamura 1987 - Mt. Madia-as, Panay Island
. halconensis Nakano & Yagishita 1993 - Mt. Halcon, Mindoro Island
Notes on Delias ganymedes :
This is only a recently discovered species, whose range appears to be extremely limited on the three islands on which it has been found.
It is to be distinguished from the other members of the group by the considerable amount of yellow on the underside hindwing which also has the veins strongly marked out in black.
Additional note : 12th October 2022
A specimen labelled "N. Luzon, Babuyan" has been found in coll OP (ex coll Sorin). If ganymedes really flies on Babuyan islands, small islands located in the North of Luzon, this would considerably enlarge the distribution of this species. Babuyan islands have to be entomologically explored, there may be interesting butterfly taxa to discover.
