Toxoproctis signiplaga Walker
comb. n.
Artaxa
signiplaga Walker,
1862, J. Linn. Soc. (Zool.), 6:125.
Nygmia
philippinensis Wileman
& South, 1921, Entomologist, 54: 274, syn. n.
Diagnosis. There is a general resemblance to cheela in facies, but for the
highly distinctive dark spot at the forewing tornus. Some specimens may have a
faintly darker submarginal fascia running anteriorly from this. The male
genitalia have the capsule much shorter relative to the size of the valves than
in munda. The aedeagus has the straight spine massive and the reflexed
one small, and there is only one spined band in the vesica.
Taxonomic note. The two taxa brought into synonymy resemble each other closely in facies
and male genitalia, though the spines at the aedeagus apex are more even in size
in philippinensis.
Geographical range. Borneo, Sumatra, Peninsular Malaysia, Philippines.
Habitat preference. This is a rare lowland species.
