While searching for Red-eyed leaf frogs, a couple of mentors, Bree and Simon, and I came across this specimen, which we immediately misidentified as an Agalychnis species. While it has distinctive red eyes, the pupils are horizontally elliptical, whereas Agalychnis has vertically elliptical pupils.

I keyed this individual to Ptychohyla legleri (formerly Hyla legleri) using these photographs and Savage’s text. It’s also on the list of frogs found at Las Cruces… but is evidently endangered! At the location these frogs were calling (there were several calling—at least four, I’d say, from the spot we searched), there were tadpoles (also pictured), so hopefully there is a successfully breeding population here.
