Pond Strong-mark Foldwing Ptychoptera contaminata

Apparently Yellow-banded Weak-mark Foldwing Ptychoptera albimana can approach contaminata in terms of strength of wing markings. The pale bands on the tarsi can be less obvious on males of that species. So although the wing markings were very clear on this individual, and there was no sign of pale bands on the tarsi, I checked the genitalia to make sure. The differences aren't completely clear to me but I'm pretty sure the side view in particular clinches the ID as contaminata.
