Diagnosis. This is the largest of the genus, a variable species, irregularly
variegated with rich brown and blackish brown, with paler yellower zones in some
specimens towards the forewing margin and hindwing dorsum. The hindwing margin
is angled centrally. The female is larger, the margins of the wings more
crenulate.
Taxonomic notes. A complex of species occurs in the Australasian tropics. Only incomptaria
has a pair of enlarged, slender, club-like setae arising from the tegumen.
Only synonyms established by dissection are listed. The following are distinct,
but related taxa: H. apicifulva Warren (New Guinea); H. nigricosta Warren
(N. Moluccas); H. plagosa Rothschild (New Guinea); H. castaneorufa
Rothschild (New Guinea).
Geographical range. Aru, New Guinea to Solomons, Queensland, Moluccas,
Sulawesi, Philippines, Borneo, Sumatra, Peninsular Malaysia (FRIM collection).
Habitat preference. Frequent in lowland forest, the species showed some
preference for wet kerangas on river terraces during the Mulu survey.
Biology. Bigger (1988) studied the life history in the Solomons. In early instars
the larva is black with raised white lateral spots on the abdomen. In later
instars it becomes paler, finally light brown, mottled longitudinally,
irregularly with darker brown. The white spots become pale cream and are no
longer raised, but there are two raised black spots dorsally on A8.
Host-plants recorded were Calophyllum (Guttiferae) Campnosperma
(Anacardiaceae), Eucalyptus (Myrtaceae), Merremia (Convolvulaceae)
and Terminalia (Combretaceae).
