Remarks. Zwick (1983) and Zwick & Sivec (1985) report this species from 19 Sumatran sites including the “Alas Valley” which, presumably, is near the sites listed above. The hemiterga of all specimens in this sample appear intermediate between the male from North Sumatra (Fig. 7c of Zwick 1983) and the one from Sandaranagung (Fig. 7d of Zwick 1983).
