Abstract: We describe a new species of frog of the genus Chiasmocleis from the montane forests of southeastern Ecuador, at the western slopes of Cordillera del Cóndor, between 1,224‑1,630 m of elevation. Based on new sequences of mitochondrial and nuclear DNA we present phylogenetic relationships of the new species and its congeners. The phylogeny shows a close relationship to C. antenori, C. carvalhoi, C. magnova and C. tridactyla. The new species is part of a clade of species that were previously assigned to the genus Syncope. This clade has a sister relationship to a clade that contains all remaining species of Chiasmocleis. The new species differs from its congeners by its reddish-brown to dark-brown (sepia) dorsum with minute yellowish-white spots. Chiasmocleis parkeri sp. nov. is similar to Chiasmocleis antenori in lacking digit I of both hands and feet but Chiasmocleis parkeri differs in coloration, arrangement and size of pale spots, and the absence of a pale line in the canthal region. We describe the calls, which are characterized by having nonpulsed notes, and we provide ecological data from the type locality and adjacent areas.
