Abstract
In South America, the stiletto fly subfamily Agapophytinae (Diptera: Therevidae) occurs predominantly in the Patagonian region where it is represented by four genera: Pachyrrhiza Philippi, Melanothereva Malloch, Entesia Oldroyd and Sigalopella Irwin & Winterton. Here we revise the genus Pachyrrhiza with an additional four new species described and figured.
