title: Genetic studies of Psammolestes tertius (hemiptera: reduviidae: triatominae) using male genital morphology, morphometry, isoenzymes, and random amplified polymorphic DNA.
abstract: Two Brazilian populations of Psammolestes tertius (Ceará and Minas Gerais) collected from thornbird nests (Furnariidae) were compared by male genital morphology, morphometry, isoenzymes, and random amplified polymorphic DNA (RAPD). Male genitalia showed no difference between the populations. In contrast, morphometry, isoenzyme, and RAPD clearly distinguished the two populations. Possible mechanisms of dispersal and the origin of Psammolestes are discussed.
