FIGURES 31–34 in Intraspecific variation in adult Uvitellina iraquensis Dronen, Ali & Al-Amura, 2013 (Cyclocoelidae: Haematotrephinae) from two collection sites of white-tailed lapwing, Vanellus leucurus (Lichtenstein) (Charadriiformes: Charadriidae), in Iraq

FIGURES 31–34. Diagrammatic representations showing the variability in the location of the genital pore (cont.). 31. Located immediately posterior to posterior margin of pharynx or a short distance posterior to it. 32. Located some distance posterior to the posterior margin of the pharynx near anterior end of esophagus. 33. Located a short distance posterior to the intestinal bifurcation. Note that the area of terminal genital canals shows the canals extending anteriorly some distance then reflexing posteriorly to join in the genital atrium at, or just posterior to the pharynx giving the impression that the genital pore opening was located more anterior in the posterior aspect of the pharynx. 34. Located a short distance anterior to the posterior margin of the pharynx and submedian. Note that the area between pharynx and intestinal bifurcation appears to exhibit contractioninduced shortening of the distance from the pharynx to the intestinal bifurcation, and a dextral rotation and displacement of the pharynx posteriorly. Abbreviations: C, cecum; ES, esophagus; GP, genital pore; OS, oral sucker; P, pharynx; PP, prepharynx; SV, seminal vesicle; U, uterus.
