Abstract: Queen ants of the Japanese ponerine genera are described, with the first key to
the Japanese genera based on the queen caste. Important queen characters are
enumerated and caste differences are discussed for each genus. Physical and
behavioral aspects of functional queens (alate/dealate queen, ergatoid, and
gamergate) in the Japanese ponerines are briefly discussed. Ectomomyrmex horni
(Forel, 1913), stat. restit., is resurrected from synonymy with Ectomomyrmex
javanus Mayr, 1867. A redescription of E. horni is presented based on
Japanese and Taiwanese specimens.
