Figure 7 in Cryptic diversity and species delimitation in the Xiphinema americanum-group complex (Nematoda: Longidoridae) as inferred from morphometrics and molecular markers

Figure 7. Factor analysis of 11 morphometric characters used to characterize Xiphinema plesiopachtaicum sp. nov., Xiphinema vallense sp. nov., and Xiphinema pachtaicum-subgroup species. Left-hand side of panels: projection of morphometric characters on the plane of factors 1 and 2 (A), 1 and 3 (B), 1 and 4 (C), and 2 and 3 (D). Abbreviations: L, body length; V, (distance from anterior end to vulva/body length) × 100; OaGR, oral aperture-guiding ring distance; Lip, lip region width; Tail, female tail length; Hyaline, hyaline region length; a, body length/maximum body width; b, body length/pharyngeal length; c, body length/tail length; c′, tail length/body width at anus.
