Lost in the city: discovery of the rare ant genus Leptanilla (Hymenoptera: Formicidae) in Macau with description of Leptanilla macauensis sp. nov

The rare ant genus Leptanilla was discovered in Macau SAR, China for the first time, which represents the second record for this genus in southeastern China. Through the detailed examination, the new species Leptanilla macauensis sp. nov. described here has unique character conditions particularly in the structure of the clypeus and subpetiolar process. Moreover, the discovery of L. macauensis sp. nov. within an island of vegetation surrounded by a dense urbanized matrix illustrates future possibilities for the discovery of new species in South East Asia, including within heavily disturbed environments
