Boarmia acutaria Snellen, 1877, Tijdschr. Ent. 20: 75.
Luxiaria acutaria Snellen; Holloway, 1976: 78.
Diagnosis and taxonomic notes. In the commoner Bornean form, both sexes resemble a
larger version of female submonstrata with less speckling over the basal
half of the wings above and more clearly defined medial fasciae below. The pale
marks in the submarginal band are larger, diffusing to the margin, particularly
at the wing apex. The specimen recorded from Kinabalu by Holloway (1976)
resembles acutaria from the Himalaya and elsewhere in Sundaland in having
the fasciae on the underside and their “ghosts” on the upperside much
reduced, narrow but still sharply defined, the forewing postmedial and
submarginal mainly separate. No differences could be observed in the male
genitalia which resembled those of specimens from the Himalaya and Java: the
angular shape of the valve ventral subapical flange is diagnostic.
Geographical range. N.E. Himalaya, Sumatra, Java, Borneo.
Habitat preference. This is an uncommon species, recorded from the
lowlands to 1500m. During the Mulu survey it was mostly encountered on the
limestone Gunung Api.
