This species was described from females, males, pupae and larvae (Takaoka et al., 2011b). It is characterized by the male antenna almost entirely yellow. The pupa of this species is similar to that of S. (G.) lurauense except terminal hooks which are widened and bear crenulated outer margins. This species is widely distributed throughout the mainland of Peninsular Malaysia.

The aquatic stages were found in small streams at low to high elevations (159–1,316 m) in Cameron Highlands and in other areas of the mainland of Peninsular Malaysia (Ya’cob et al., 2016a, b).
