Plusia megaloba Hampson
Plusia megaloba Hampson, 1912, J. Bombay nat. Hist. Soc. 21: 1225.
Plusia megaloba Hampson; Holloway, 1976: 32.
Diagnosis
The forewings are rich brown with the dot of the central maculation expanded into a very large rounded triangle.
The female has a more uniformly brown hindwing than the male.
Taxonomic Notes
In the male genitalia the aedeagus has an extremely large basal bulb in which the abnormally long vesica is retained; the vesica has a single apical cornutus; the valves are relatively broad.
The modifications of the male eighth abdominal segment are reduced and there are no lateral hair tufts.
There is thus some similarity to Zonoplusia ochreata.
Geographical range
N.E. Himalaya, Peninsular Malaysia (G. Ijau), Borneo.
Habitat preference
Bornean material is restricted to three specimens from G. Kinabalu, taken between 1600m and 2000m in well developed upper montane forest.
