REMARKS
Our specimens are very similar to A. recurvata Cordell, 1952 from the Late Pennsylvanian (Late Carboniferous) of Missouri ( USA; Cordell 1952) and Late Permian of South China ( Shi & Chen 2002) but differ in having a more concave AVB, a VB slightly concave at mid-L and the PDB connection with DB forming a more or less marked angle.
