Remarks. This species is widely distributed in southern Asia with subtropical and tropical climates, with some local color forms. Among the specimens we examined as mentioned above, those from Sulawesi I. have the first two metasomal terga colored darker brown in the apical half and sometimes have the mesepisternum largely marked with black, while the other specimens (Borneo I., Sumatra I. and Java I.) have the first two metasomal terga colored brown rather than dark brown in their apical half and the mesepisternum both anteroventrally and posterodorsally marked with black.
