The species is closely allied with L. lamprodesma Meyrick, from Java
but is larger, deeper orange, the markings differ slightly. The genitalia
show considerable differences from those of the above named Javanese
species and are quite distinct. Apparently Meyrick refers to
this species in his description of lamprodesma, where he states: "I
have a closely allied undescribed species from the Philippines"
(Zool. Meded., vol. 7, p. 85, 1922). The long tufts of the hind tibia are
peculiar.
