Aenictus changmaianus

No biological information is available for A. changmaianus. However, it has been found in highland seasonal forests (hill evergreen forest) and disturbed areas in northern Thailand (900–1500 m). In eastern Thailand and southern Vietnam it has been collected from lowland seasonal forests (dry evergreen forest), secondary forests, and plantations (160–700 m), thus this species probably ranges from lowland to highland and inhabits both primary and disturbed forests. (Jaitrong & Hashimoto, 2012).

Identification
Aenictus changmaianus is very similar in general appearance to Aenictus minutulus and Aenictus minimus. However, A. changmaianus is separated from A. minimus by the dentition on the basal margin of the mandible and antennal scape being relatively longer than in the latter (scape index 67–72 in A. changmaianus; scape index 63–64 in A. minimus). It is distinguished from A. minutulus by the large metapleural gland bulla relatively small in A. minutulus).

Distribution
This taxon was described from Thailand. It is also known from Vietnam and Cambodia.
