Variability and fluctuating asymmetry of mid tibial spurs in Eucremastus Szépligeti (Hymenoptera, Ichneumonidae, Cremastinae)

Abstract:

The presence of one or two spurs on the mid tibia has been widely used as a diagnostic character in many taxa, but it has been discovered to be a highly variable character in the Cremastinae genus Eucremastus. Variation in the number of mid tibial spurs and occurrence of asymmetry in this genus was studied. The anomalies observed in this character are classified into three categories. Other non-cremastine genera traditionally characterized by having a single mid tibial spur were studied, but no anomalies were found. The taxonomic implications of this variation are discussed.
