“Eutane”
nivea Hampson
Eutane nivea Hampson,
1905, Ann. Mag. nat. Hist. (7), 15:
439.
Diagnosis and taxonomic note. The
facies is mostly satiny white, the forewings with a black discal dot. The
straight forewing margin, with ochreous and dull brown marking, including a
projection basad at one-third from the dorsum, are distinctive. The male
genitalia have little in common with typical Eutane.
The uncus is a slender rod, the valves are tapering, basally very much
expanded, the saccus has a distinctive projection, and the aedeagus vesica is
extensively but sparsely scobinated, with a sclerotisation of the ductus
ejaculatorius. The female has rather square ovipositor lobes, a moderate,
straight, sclerotised ductus bursae that opens subbasally and slightly laterally
into a large, pyriform corpus bursae, the surface of which is finely invested
with shallow pimples throughout.
Geographical range. Borneo.
Habitat preference. This
is a rare species of lowland forest, including coastal and swamp forest. It has
not been taken above 250m.
