Three morphologically similar Bahamian scoliid wasps are traditionally described as two species, Campsomeris bahamensis and C. trifasciata, the latter of which is divided into two subspecies: C. t. trifasciata and C. t. nassauensis. We examined these taxonomic groups by comparing the genetic diversity of different Campsomeris populations collected at various locations on several islands. DNA was extracted from individual male and female specimens and preferentially amplified by the polymerase chain reaction, using a unique random primer for each analysis. The DNA products were compared by electrophoresis. Results indicate overlapping genetic profiles between these three taxonomic groups. The genetic variation between these three taxa is similar to the variation found within one taxon collected from different islands.
