Reanalysis of TM characters including type specimens

Reanalysis of traditional morphometric characters for discriminating among final species hypotheses and classifying type specimens (when available). Classification results based on discriminant functions calculated from an optimal combination of characters (see Table S6 for details), separately for four species groups. We defined these groups according to ovipositor length (i.e., number of articles on gonapophysis VIII). This corresponded to the first steps in the Machilis identification key of Palissa (1964). Type specimens were not included in the training set. Classification success is given as the actual number (absolute) and the percentage (%) of individuals classified in original and leave-one-out cross-validated (LOOCV) discriminant analyses. Correct and wrong classifications are highlighted in green and red, respectively. dis = M. distincta, eng = M. engiadina, rub = M. rubrofusca, tic = M. ticinensis, tir = M. tirolensis, vag = M. vagans, spE = M. sp. E, spF = M. sp. F.
