Fascellina albicordis Prout,
1932, J. fed. Malay States Mus. 17: 94.
Fascellina albicordis Prout;
Holloway, 1976: 77.
Diagnosis. The wings are a rich, blackish brown with a very prominent white discal
patch on the forewings; this latter is smaller or absent in castanea which
also has a greener tinge to the wings. In castanea the forewing
postmedial below has a much stronger angle subcostally, the distal border of a
darker brown bar. On the hindwing below, the medial and submarginal fasciae fade
away towards the tornus and are convergent. In castanea they are more
uniform in development, diverge, then converge and enclose a brown discal mark.
Taxonomic notes. This taxon is paralleled (not necessarily in a sister-relationship) in
Sumatra by the similarly montane F. aua Prout.
Geographical range. Borneo.
Habitat preference. This is a montane species, frequent from 1620m to
1930m on G. Kinabalu and at around 1790m in upper montane forest on G. Mulu.
