Diagnosis. This species is somewhat variable and sexually dimorphic, the males
being darker than the females, and some of the smaller females being liable to
confusion with grey Gyrtona species as they are pale with reduced dark
fasciation and an enhanced diffuse pale streak bisecting the forewing apex. But
there is a curved dark subbasal fascia typical of Savoca; the post-medial is somewhat oblique relative to that of other Bornean species and
distinctively darkened at one third and two thirds.
The male genitalia indicate that this is a true Savoca: the
species is distinguished by the angling or strong curvature of the dorsal arm
of the valve, the lateral coremata on the 7th abdominal segment, and the
presence of a subbasal process on the dorsal arm of the valve as in conglobalis
but without a flange on the aedeagus.
Geographical range. Sundaland, Philippines, Sulawesi, Ceram, New Guinea.
Taxonomic note. The holotype male from Ceram has an uncus broadened abruptly at the
middle, ventrally, this extending evenly to the apex; subbasal processes from
the valve costa are much more prominent than in Bornean and Sulawesi males.
Habitat preference. Three specimens have been taken in tall montane
forest at Mesilau (1500m) on G. Kinabalu. During the Mulu survey a singleton was
taken in upper montane forest at 1780m on G. Mulu.
