Abstract
A new poeciliid fish is described from material collected in the Río Coto basin in southeastern
Costa Rica and western Panama. Brachyrhaphis roseni is similar to B. rhabdophora in lacking several specialized characteristics which are found in some of the other seven known congeners. B. rhabdophora replaces the new form in adjacent drainages to the north and B. episcopi, likewise, replaces B. roseni in central Panama.
