I have several specimens of Chrysodema but these have been collected only in three islands of the country: Mindanao, Bohol and Homonhon (off Samar) while a few were given to me and were collected in one of the Babuyan Islands.
From these, I have only identified four with the correct species name using Lander’s paper. The rest are really difficult considering that the paper is written in French and there are limits to what online translations can do especially that these has to be exact. Members of this genus is also characterized by lots of variations that make it all the more difficult to identify these.
The genus Chrysodema, even with a key is really a challenge to identify.
