This species was discovered by Natterer, and confused with 

 P. longuernarei. The most important point of distinction 

 seems to consist in the form of the tail feathers, which in 

 Ph. nattereri are rather narrow, while they are usually broad 

 in P. longuernarei. The colouration of the tail is also 

 different, the two middle feathers being pale brownish-gray
