Trachycephalus typhonius Common Milk Frog
Some other names for this species:
Veined Treefrog, Pepper Treefrog, Veined Milk Frog, Vein-eyed Glue Frog, Veined Frog, Warty Treefrog
This species has had a particularly convoluted taxonomic history. You'll often see it referred to as Phrynohyas venulosa or Trachycephalus venulosus. In 2010, Lavilla et al published a work of taxonomic detective work that resulted in the species name T. typhonius.

Common Milk Frog (Trachycephalus typhonius)
This species can be distinguished from its close relative the Amazon Milk Frog by its coloration and its crazy eye pattern.

Common Milk Frog (Trachycephalus typhonius)
In two previous visits to this reserve I had seen none of these frogs, but on this trip I saw two. This second one was perched very close to where the first one had been three nights earlier. At first glance I thought it might be the same individual frog, but a closer look shows that it has several minor differences, most obviously in the eye pattern.
