Throana
flavizonata Hampson
Throana
flavizonata Hampson, 1926, Descr. Gen. Spec. Noctuinae, p. 590.
Diagnosis. This is the smallest Bornean species,
darker grey than congeners, with irregular white postmedials on all wings that
fade away subcostally and are edged distally by a narrow zone of pale red.
Taxonomic note. In Seram there is an externally
similar species with more robust valves and a shorter aedeagus vesica with a
series of larger spines basally (slide 18905). This may be conspecific with T. blechrodes Turner from
Queensland.
Geographical range. Borneo,
Peninsular Malaysia.
Habitat preference. The holotype is from Sandakan, and there is a specimen from Bidi in
Sarawak. A male was collected by the side of a road in
logged forest at 100m near the Danum Valley Field Centre in Sabah. S.J. Willott (unpublished data) also recorded the species with greater frequency
in logged forest in the Danum Valley locality, and Chey
(1994) noted several specimens in lowland softwood plantations.
