Eucosmophora pouteriae is a moth of the family Gracillariidae. It is known from Costa Rica.[1]
The length of the forewings is 3.2–3.6 mm for males and 3.7 mm for females.[2]
The larvae feed on Pouteria campechiana. They mine the leaves of their host plant.
The specific name is derived from the generic name, Pouteria, of the only recorded larval host.
