Euproctis eva Schintlmeister, 1994: 129.


Orvasca eva


Diagnosis.
The facies is somewhat similar to that of (See Micromorphe chalcostoma Collenette), with pale yellow margins costally and distally around a medium to pale, pinkish brown-grey. The distal margin of the forewing is more irregular, with the hint of a central projection to the brown-grey as in kilanas sp. n. and the next species.

Taxonomic note. The male genitalia indicate this species is an Orvasca, having both the rugose uncal structure and the saccular flap. The valves have some similarity to those of the waterstradti group, but with the ventral arm much narrower.

Geographical range. Sumatra, Borneo.

Habitat preference. Four specimens were taken during the Mulu survey in three lowland forest types: alluvial, on limestone, and heath forest.
