Eugoa bipunctalis van Eecke  
Eugoa bipunctalis van Eecke, 1926, Zool. Meded. Leiden, 9: 264.

Eugoa bipunctalis
(x 1.56)

Diagnosis and taxonomic note.
This and the next species are the largest in Borneo and have something of the facies of the first group, but are distinguished by the presence of the discal dots. The submarginal has more pronounced linearity and irregularity of course. Distinction of the two species is presented in the diagnosis of the next. Bornean specimens differ from typical Sumatran bipunctalis in having the costal part of the valve apex more strongly produced.

Geographical range. Sumatra, Java, Borneo.

Habitat preference. The species is infrequent in lowland dipterocarp forest, and occurred with slightly greater frequency in lower montane forest at 1000m on G. Mulu during the Mulu survey.
