Fig. 10 in Family Tylenchidae (Nematoda): an overview and perspectives

Fig. 10 Phylogenetic analysis of the family Tylenchidae inferred from concatenated sequences of the D2–D3 domains of the 28S and 18S rRNA gene. For separated 28S and 18S phylogenies, see Qing et al. (2017). Both Bayesian inference (BI) and maximum likelihood (ML) methods were used for tree reconstruction, but only ML topology is shown. Branch support values are providing as BI/ML. The sequences used for this phylogeny are listed in Electronic supplementary material. Asterisk (*) denotes significance level of the support values: *, 50–80; **, 80–100 for ML bootstrap; *, 50–90, **, 90–100 for BI posterior probability; −, not supported. The most important morphological supports for each clade are illustrated on right side of the tree. 1 Labial plate deeply and broadly indented dorsally and ventrally. 2 Labial region offset from body by distinct constriction, four lobed, and each lobe with a seta. 3, didelphic reproductive system. 4 Four incisures in lateral region. 5 Stylet with pronounced knob. 6 Amphidial apertures bound on peri-oral disc, cuticle coarsely annulated with longitudinal ridges. 7 Amphidial apertures bound on peri-oral disc, cuticle without longitudinal ridges. 8 Vagina with swollen wall in distal part. 9 Amphidial apertures are broad oblique slits, starting posterior to the level of four cephalic papillae and continuing to sides of head. 10 Tail short and conical. 11 Stylet with flange-like knobs. 12 Lateral field with offset ridge, comprising small sub-ridges. 13 Vagina with swollen wall in proximal or middle part. 14 Head can be dorso-ventrally compressed or more rounded, with pouch-like amphidial fovea. 15 Bursa lobed, rectangular. 16 Cephalic region strongly flattened dorso-ventrally, lacking labial disc, long amphidial aperture, large pouch-like amphidial fovea. 17 Lateral region with one offset ridge forming two incisures. 18 Cephalic region continuous, very less framework, stylet knob minute and separate. 19 Long slit-like amphidial aperture, large pouch-like amphidial fovea. 20 Labial plate that has four narrow lobes with tips detached from the adjacent cuticle. 21 Amphidial aperture elongated, slender, dorso-ventrally oriented entirely on labial plate, cuticle with zigzag pattern. 22 Male without bursa.
