Material examined. Indonesia: Sumatra, Aceh, Mt. Leuser National Park, Ketambe Research Station, Alas River, 3° 41’ N, 97° 39’ E, 350 m, 5 September 1989, ROM 893053, W.K. Gall, 1 ♂, 7 ♀ ( MZB, ROM). Remarks. This species is known from about a dozen sites on Sumatra but had not previously been reported from this locality. Present collections are from most months between March and December ( Zwick 1983; Zwick & Sivec 1985). Zwick’s (1983) description of the egg from light microscopy is supported by our figures from scanning electron microscopy ( Figs.1‐2 View Figs ). The chorion is covered throughout, except for a bare area surrounding the collar, with closely grouped, fine shallow pits, and the sessile collar consists of a shallow depression from which a long anchor pedicel (broken in our specimen) extends.
