New distributional and biological data for three species of Stenodynerus (Hymenoptera, Vespidae, Eumeninae) from Panama

We provide new data on the distribution and biology of the three Stenodynerus species (Hymenoptera, Vespidae, Eumeninae) from Panama: Stenodynerus iolans (Cameron, 1905) is recorded for the first time from Panama; several localities are added to the known distribution in Panama of S. farias (Saussure, 1857); and S. otomitus (Saussure, 1857), currently known as a ground-nester, was found emerging from exposed cells together with Ipsiura pilifrons (Cameron, 1888) (Hymenoptera, Chrysididae).
