Merodon unicolor complex

Geometric morphometric analyses of wing shape revealed the same pattern for pooled sexes and for the males separately, so we only present results based on the pooled dataset. Stepwise DA revealed that M. unicolor and M. albidus differed significantly in wing shape (F 10, 21 = 76.5617, P <0.01), with an overall classification success of 100%. Moreover, the classification success of our Gaussian naïve Bayes’ classifier was 97%. Only one specimen of M. albidus was misclassified as M. unicolor . The CVA generated one highly significant axis that differentiates M. unicolor from M. albidus (CV1: Wilks’ Lambda = 0.0255; χ2 = 88.0977; P <0.01). Differences in mean wing shape between these two species are depicted by superimposed outline drawings in Figure 4C.
