Fig. 2From: Morphometric variability among the species of the Sordida subcomplex (Hemiptera: Reduviidae: Triatominae): evidence for differentiation across the distribution range of Triatoma sordida a Specimens of Triatoma garciabesi (i), T. guasayana (ii), T. patagonica (iii) and T. sordida (iv) from Argentina and T. sordida from Brazil (v). Linear measurements and landmark positions used for the head (b), pronotum (c) and forewings (d) of the four species included in this study. b Head width (HW), preocular length (PL), head length (HL), preocular width (PW), landmark positions 1–4. c Pronotum width (PW), pronotum length (PL), landmark positions 1–4. d Forewings, landmark positions 1–8Back to article page
