Dilobocondyla fouqueti

Dilobocondyla fouqueti is distributed in Vietnam and China. All recent Hong Kong records are from mature patches of lowland forest. The species is uncommon, with only a handful of records from well-surveyed areas, and is at least partly arboreal (Bharti & Kumar, 2013).

Identification
There is noticeable colour variation in D. fouqueti and worker length is quite variable, ranging from 4.5 to 7.04 mm. (Bharti and Kumar 2013)
