Diagnosis. Both this and the next species have a yellowish fawn ground colour, not
quite as bright as in the argyromma group, and with the hindwing discal
spot small, yellowish, ringed brown, never blackened. All these yellowish
species treated early in the sequence have the costa and antennal shafts brown.
Genitalic examination is necessary to distinguish the two as described below.
Taxonomic notes. There are coremata on the fourth sternite, the longest element of which
terminates in a structure similar to that in argyromma but much shorter
and broader, and at the base of the genitalia. The aedeagus is only weakly
convolute but this extends to the ductus ejaculatorius. The dorsal part of the
tegumen is broadly serrate. The hind-tibia is of normal length, but there is a
scale tuft on the femur.
Geographical range. Singapore, Peninsular Malaysia, Borneo.
Habitat preference. All material seen is from 100m or below, taken in
alluvial swamp, heath and coastal forest types.
