Table 4 Mahalanobis distances between pairs of species performed for shape variables of the head, pronotum and wings. Interspecific comparison: Triatoma garciabesi (T. gar), T. guasayana (T. gua), T. patagonica (T. pat) and T. sordida (T. sor). Comparison among closely related taxa: T. sordida from Argentina (T. sor Arg), T. sordida from Brazil and Bolivia (T. sor BB) and T. garciabesi (T. gar)

From: Morphometric variability among the species of the Sordida subcomplex (Hemiptera: Reduviidae: Triatominae): evidence for differentiation across the distribution range of Triatoma sordida
