Named after the hero of the famous ancient Peruvian 

 drama '' OUantay/' A species without striking structural 

 features, but readily distinguished by its fulvous colour, 

 which makes it look like Xenoglossa must elina (Fo\) . The 

 eyes converge more above than in P. matutina. P. eburnea, 

 Friese, from Peru, is readily distinguished by its dark 

 tegumentary colours.
