Morphological variation in G. firmus consistent with proposed cryptic species. A. Male femur length; B. Female femur length; C. Relative ovipositor length (ovipositor length/femur length). There is considerable morphological variation among northeastern, Florida, and Texas G. firmus, which is similar to the magnitude of morphological divergence observed in the closely related species G. thinos. This combined with genetic divergence suggests there may be cryptic species in what is currently considered G. firmus. Boxplots indicate the mean values of each trait, quartiles, the range of the data (whiskers), and outliers. Individual data points are overlaid as scatterplots. Letters indicate the significant differences among groups (PWRST with corrected p-values < 0.05), and exact p-values are presented in Suppl. material 1: table S3.
