1 Transferred from Issidae by Gnezdilov (2007).
2 Described from Eocene Baltic amber. Provisionally placed in Tropiduchinae by Gnezdilov (2013b).
3 Described from Eocene imprint of Green River Formation, Colorado, U.S.A. Provisionally placed in Tropiduchinae by Gnezdilov (2013b).
4 The taxon was established as subtribe Gaetuliina Fennah, 1978 in the tribe Bladinini of the family Nogodinidae. Gnezdilov (2007) transferred it as tribe, to Tropiduchidae. Gnezdilov (2013b) synonymized Gaetuliina under Elicini Melichar, 1915. Provisionally placed in Elicinae by Gnezdliov (2013).
5 Described from Eocene Baltic amber. Provisionally placed in Elicinae by Gnezdliov (2013b).
6 Described from Eocene Baltic amber. Provisionally placed in Elicinae by Gnezdliov (2013b).
