Although Moore stated his specimen of buxtoni from Buxton came from Sumatra, there may have been a location error since in later literature buxtoni has always been quoted to be from Borneo.

Fruhstorfer in 1909 named taxon trebonia from Sumatra as K. buxtoni trebonia.
This seem to have been changed to K. limborgi trebonia & currently as K. paralekta trebonia.
A specimen from Sumatra below.

They really should do a DNA analysis to determine if the taxa have evolved far enough to be considered separate species.
Currently the species in Sundaland would be.
K. limborgi mainland P. Malaysia.
K. buxtoni Borneo.
K. paralekta trebonia ..Sumatra.
K. paralekta paralekta ..Java.
