Diagnosis. The forewing is pale, with broken brown fasciae and longitudinal streaks
and a small, pale, oval subtornal patch. The hindwing fasciation is straight,
the apex rounded with slight dentations at the veins, rather than being excavate
as in the only other species with straight fasciae.
Taxonomic notes. Warren attributed this species to Hampson, but no earlier reference has
been located. A note by A. Watson in the BMNH collection indicates that Neophalacra
laticornis Roepke (Sumatra) is probably a synonym, but the type has not been
located.
Geographical range. Borneo, ?Sumatra, Peninsular Malaysia.
Habitat preference. The holotype is from the Matang Road in the lowlands
of Sarawak and there is a second, less heavily marked male from Sarawak but
without precise data.
Biology. H. Steiner (in litt.) has reared the species in Peninsular
Malaysia. The host-plant was the palm, Plectocomiopsis geminiflorus.
