Body cylindrical, tapering towards anterior extremity. Cuticle with transverse rows of dots, lateral differentiation consisting of larger, irregularly-spaced dots. Eight rows of short, sparse somatic setae. Head set-off by constriction immediately posterior to cephalic setae. Inner and outer labial sensillae indistinct, four cephalic setae. Amphideal fovea spiral, 2.5 turns, located at level of cephalic setae. Buccal cavity tubular, 4 μm deep, 1 μm wide, surrounded by pharyngeal muscles. Marginal tubes beginning from base of stoma. Pharynx gradually swelling, not forming true bulb, cardia short. Nerve ring near middle of pharynx, situated anteriorly to secretory-excretory pore. Cellular body of ventral gland near level of cardia. Intestine wall with numerous small, colourless granules, and clusters of clear circular inclusions, mostly in posterior portion of intestine (
