Specimen labels

A nest of B. obscurans from a secondary forest in Macau contained about 400 individuals. The nest was covered by abundant rotten wood-litter and leaf-litter in an area with very moist soil. This ant nest was adjacent to a termite colony (Macrotermes barneyi) found nesting in wood laying on the ground surface. (Leong 2017)
