Western Pygmy Possum|
The following appears to be the only cross reported for this family:
Cercartetus concinnus [Western Pygmy Possum]
× Cercartetus nanus [Eastern Pygmy Possum] These possums have a parapatric contact zone near Adelaide (southeastern Australia), but the author has not as yet encountered any explicit report of hybridization. Smith and Hume 1984 (p. 583).
