|---|---|---|
| A. Huguet et al. 2002 | Tillyard (1926) characterized this family by the presence of ‘only two cross-veins between consecutive branches of the main veins in the distal portion of the wing’. This character is far from being sufficient to define correctly a family of Odonatoptera, because it is simply due to the relatively few number of cells in the wing. We propose to characterize this family by the following synapomorphy: ‘presence of a large cell in cubito-anal area between CuP and CuA, at the base of distal free part of CuP’. These taxa also have a relatively reduced cubito-anal area and narrow wings, with few cells. They also have a relatively narrow area between MP and IMA. |
