Leptobrachella picta has been reported from hilly and montane terrain (500–1.500 m asl) in northern Borneo, where it lives in primary or old secondary forest. It is commonly found near small forest streams. 

This species is similar to the other Leptobrachella species (those formerly in Leptolalax, i.e., subgenus Leptolalax) in body shape and size (~ 35 mm in males, ~ 40–45 mm in females). 

It is distinct from all other species in the genus by clearly defined dark spots from the snout to the groin. The background color is mid to light brown. The dark markings along the sides and on back are bordered by light lines. The upper sector of the iris is orange-red.

To our knowledge tadpoles have not been assigned unequivocally to this species. But we expect tadpoles much of the typical type in the genus. See L. gracilis, for example.
