We describe a new species of Chiasmocleis (Anura: Microhylidae) from lowland rainforests in the western Amazon basin of Peru (near Iquitos, Departamento de Loreto). The species differs from congeners in the Amazon basin by its large size ( it is the largest known Chiasmocleis species), bright yellow iris, a grey dorsum with reddish blotches posteriorly and on limbs, and a creamy white venter with bold dark mottling with pale centers. The new species also differs from two other sympatric Chiasmocleis species at 12S-16S mitochondrial DNA (6.1% and 11.9% sequence divergence between the new species and C. ventrimaculata and C. bassleri, respectively). A comparison of the new species with other microhylids found in the western Amazon basin is provided.
