TABLE 5 in Unravelling cryptic species diversity in eastern Nearctic paper wasps, Polistes (Fuscopolistes), using male genitalia, morphometrics and DNA barcoding, with descriptions of two new species (Hymenoptera: Vespidae)

TABLE 5. Discriminant function analysis: relative importance of different morphometric parameters in distinguishing Polistes hirsuticornis sp. nov., P. parametricus sp. nov. and similar species. The relative importance (Wilks' λ; lower values indicate greater relative importance) and significance (F statistic) are indicated for each parameter (p <0.001, except for genal width / eye width in males which was p = 0.001). The analysis included specimens of P. hirsuticornis, P. parametricus, P. bellicosus, P. fuscatus, and P. metricus (see Tables 2 and 3). Parameters are sorted by increasing Wilks' λ values for females.
