Figure 3 Mesosoma length and tergite 3 slenderness (length/width) of 107 male rhyssine wasps. Males of all species had similarly slender tergites 3, irrespective of body size. The only exception was Epirhyssa overlaeti, whose tergites got significantly more slender with body size when the significance was estimated by one-tailed correlation (c.f. Figure 4).
