Which species holds the distinction of being the smallest Australian wallaby?
Answer
The Parma Wallaby (*Notamacropus parma*)
The Parma Wallaby, scientifically designated as *Notamacropus parma*, holds the specific distinction of being the smallest wallaby species native to Australia. This diminutive size contrasts sharply with other members of Macropodidae. Interestingly, its placement within the genus *Notamacropus* suggests a closer recent evolutionary split between it and the significantly larger Red-necked Wallaby, which also belongs to *Notamacropus*, indicating that size alone is insufficient for determining fine-scale evolutionary relationships.
