抄録

Ba Vi (1,296 m alt. at the highest peak) and Tam Dao (1,592 m alt. at the highest peak) are national parks located 50 km west of and 75 km north of Hanoi City, respectively. During the years 1998-2002 we surveyed ants in both areas. The present paper gives an inventory of the results, counting 218 species belonging to 56 genera in 11 subfamilies, though 133 species were left unidentified. The species number for each area is comparable, 151 in Ba Vi and 151 in Tam Dao, of which 84 species were observed in common. The result was assessed in terms of workload of surveys, species composition, comparing with the faunas of Cuc Phuong and Hoang Lien Son.
