). Cuticle transversely striated, about 1 µm between two striations. Lips high, with six inner labial setae, 4–6 µm long. Six outer labial setae and four cephalic setae arranged in one circle. Outer labial setae 17–19 µm long; cephalic setae 9–12 µm long. Numerous long somatic setae in pharyngeal region, 20–35 µm long. Amphids difficult to distinguish, circular, 7 µm in diameter (27% of the corresponding body diameter), situated posterior to the buccal cavity, about 24 µm from anterior end. Buccal cavity broad, extended anteriorly with an intermediate annule; anterior part cylindrical, posterior part conical, 22 µm deep and 15 µm wide. Pharynx cylindrical, with a series (18) of bulb-like muscular swellings, each with thick cuticular lining, 8–16 µm long and 17–19 µm wide. The adjacent pharyngeal bulbar swellings separated by transverse elliptic dilated structures and internal lumen. Cardia large, conical, 13 µm long. Nerve ring located at 33% –42% of the pharynx length from anterior end. Excretory pore and ventral gland not observed. Tail narrowing abruptly immediately posterior to cloaca; conico-cylindrical, 5.6–6.2 times cloacal body diameter, with several short setae. Tail tip slightly swollen, bearing two terminal setae, 10 µm long.
