Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| A. Huguet et al. 2002 | Tillyard (1926) characterized this genus by the presence of an ‘abnormal’ pterostigma, crossed by RA. Thus, we propose to characterize this genus as follows: ‘no strong notch of the posterior wing margin at the distal end of MP and at the distal end of MA and RP3/4’ (reversions); ‘less than five antenodal cross-veins of the first row, between C and ScP’ (strict synapomorphy). |
