Arborophila is a bird genus in the family Phasianidae. 
The genus has the second most members within the Galliformes after Pternistis, although Arborophila species vary very little in bodily proportions with different species varying only in colouration/patterning and overall size. 

Phasianidae from Phasianus: Latin for "pheasant", derived from the Ancient Greek φἀσιἀνος, phāsiānos, meaning "(bird) of the Phasis", the River Phasis (now the Rioni) in Colchis on the east coast of the Black Sea (now western Georgia).
Arborophila: the Latin arbor, arboris meaning "tree" with the Ancient Greek philos meaning "-loving".
