ABSTRACT
The limoniid fly Trentepohlia (Mongoma) pouilloni n. sp. Ngô-Muller, Garrouste & Nel, is the first fossil insect to be described from Sumatra. On the basis of its wing morphology and venation, it is very similar to the extant Sumatran species Trentepohlia (Mongoma) pennipes (Osten Sacken, 1888), supporting a Miocene rather than older age for the amber. By comparison with the few available data on the biology of the extant species of the subgenus Mongoma, it probably lived in a warm and humid forest where it was trapped in dipterocarpacean resin. The wide Cenozoic distribution of the subgenus Mongoma in Europe and South-East Asia is in accordance with its extant circumtropical distribution.
