Belonging to the group containing hosei and thom.\si, this species 

 is quite differently colored. The white crown is encircled by a dark 

 line as in P. thomasi, but there is no central line in the white so 

 conspicuous in the species named. It is strikingly different also in its 

 white face, hands, feet and legs.
