Morphology and Anatomy:

Pseudocheironchus ingluviosus is characterized by:

six conical inner labial papillae; six small outer labial setae and four slightly longer cephalic setae in one circle.
strong mandibles, each with two pairs of four blunt hooks, mandibles joined by a membrane with slender cuticularised ridges at their junction,
Posterior buccal cavity with three equal mandibles, one dorsal and two sub-ventrally. Each mandible consists of a heavily cuticularised axis with a longitudinal groove; anterior portion consists of two sets of four blunt hooks; posterior extremity of axis rounded.
pharynx short, with conspicuous oval-shaped anterior bulb surrounding posterior portion of buccal cavity,
nerve ring at middle of pharynx. secretory-excretory system present, cellular body of ventral gland situated 1.5 cbd posterior to pharynx, pore situated near posterior extremity of posterior pharyngeal bulb
multispiral amphideal fovea with 5.0 turns,
short conical tail with rounded end

	Females: didelphic-amphidelphic with reflexed ovaries. Vulva located slightly pre-median. Vaginal glands present, Pars proximalis vaginae surrounded by constrictor muscle Ref: Leduc, 2013
