Description
Morphology
Female: 5.5 to 6.4 mm long by 270 to 315 µm wide. Cuticle transversely striated up to the level of the oesophagus ( Figs. 2B and C View FIGURE 2 ). Lips not salient. Buccal cavity about 7 µm deep. Oesophagus 569 µm long, consisting of an anterior cylindrical corpus, 432 µm long by 46 µm wide; an isthmus 36 µm long; and a posterior valvular bulb 102 µm in diameter. Intestine dilated anteriorly to form a cardia. Nerve ring 261 µm from the anterior end of body. Excretory pore posterior to base of oesophagus, 774 µm from the anterior extremity. Anus 270 µm from posterior end of body; tail short, attenuated conical ( Fig. 2F View FIGURE 2 ). Vulva just behind the middle of body ( Fig. 2D View FIGURE 2 ). Ovaries lying in the opposite direction to their corresponding uteri and reflexed near their terminations; uteri divergent. Eggs ellipsoidal, almost spherical ( Fig. 2E View FIGURE 2 ), 57 µm long by 42 µm wide.
