Abstract: In north and north-central Vietnam colony structure and other aspects of biology of Cladomyrma scopulosa Eguchi & Bui associating with a tree species Saraca dives Pierre were recorded. Within the genus Cladomyrma a colony structure with multiple dealate queens has been seen almost exclusively in C. scopulosa. Our limited observations suggest that secondary polygyny at the early founding stage, or even primary polygyny, often occur in C. scopulosa. The colony may become progressively more polygynous by accepting supplementary queens. Genetic relatedness among dealate queens, however, was not estimated in the present study.
