Family Acrolepidae ALDINGER, 1937

Kazanceva-Selezneva (1977) published a new definition of the family Palaeoniscidae and classified Progyrolepis to this family. Štamberg (1991) and Poplin (1999) placed Progyrolepis into the family Pygopteridae ALDINGER, 1937 . The distribution of the cheek bones and in particular the opercular apparatus place Progyrolepis in the family Pygopteridae , but the shape of the parasphenoid and curved interfrontal suture do not fit in the original description of Pygopteridae submitted by Aldinger (1937). The presence of conical teeth and antoperculum in Progyrolepis heyleri exclude this species from the family Palaeoniscidae in the sense of Kazanceva-Selezneva (1977). The genus Progyrolepis is provisionally included here to the family Acrolepidae ALDINGER, 1937 because characters in this genus best match the definition presented by Aldinger (1937).
