ABSTRACT. The millipede Poratia insularis (Kraus, 1960), previously known from near Iquitos, Peru only, has been found in the environs of Manaus and in Amapб state, Brazil. Apparently being terricolous and restricted to various types of inundation forest in Central Amazonia, and to a palm plantation in eastern Amazonia, this small species appears to be far less common than the sympatric, often syntopic and similarly trans-Amazonian congener P. obliterata (Kraus, 1960). Some illustrations are provided to facilitate the recognition of both these species.
KEY WORDS: Diplopoda, Poratia insularis, new records, Brazil.
