Until recently, all species in the group were treated as belonging to the single genus "Trigona". Tetragonula iridipennis belongs to the smaller Iridipennis species group which includes four primary species: Tetragonula iridipennis, Tetragonula praeterita, Tetragonula ruficornis, and Tetragonula bengalensis. These four species were proposed in the 19th century and were poorly characterized. They... Wikipedia →
