Pompilidae is an important group of wasps, serving as models for ecological and evolutionary studies. Although pompilids are quite uniform in their biology, they exhibit considerable diversity in ethological types. In order to determine if any evolutionary trends in ethological types actually exist, a solid phylogenetic foundation is needed. A phylogenetic study of Pompilidae was performed based on more than 80 morphological characters. Over 70 terminals were coded at a species-level. Results suggest that the current phylogeny consisting of six subfamilies does not reflect phylogenetic relationships and that the old classification of (Ceropalinae + (Pepsinae+Pompilinae)) is a better representation. Furthermore, several interesting evolutionary trends were revealed.
Species 1: Hymenoptera Pompilidae Ceropalesrugata Species 2: Hymenoptera Pompilidae Tachypompilusunicolor Species 3: Hymenoptera Pompilidae Psorthaspismagna Keywords: spider wasps, ethology
