“Giaura”
lichenosa
Hampson
Ptisciana lichenosa Hampson, 1896, Fauna Br. India, Moths, 4: 527.
Diagnosis. The large, rather trapezoid subbasal white area of the forewing
is distinctive, though a similar mark is seen in females of the larger and
browner Beana
terminigera.
Taxonomic note. In addition to the distinctive facies, the male genitalia
have a long, rather angular tegumen, and the black-scaled processes of the valve
are club-like, the scales restricted to the apex. Tymbal organs are lacking.
Geographical range. N.E. Himalaya, Borneo, Bali, Sulawesi.
Habitat preference. The two specimens taken in recent surveys were both from
lowland forest: at Ulu Dusun 30 miles west of Sandakan in Sabah; at 250m on the
slopes of the limestone G. Api taken during the Mulu survey.
