Description:
The average body length is about 3cm. The body is divided into an anterior proboscis, trunk, and a short eversible caudal projection. The proboscis consists of an introvert, collar, and an everted pharynx. The introvert is smooth and narrow, terminating anteriorly with a circle of long spines. The unarmed collar is long and tapers anteriorly. The everted pharynx is long and lined with spinose or cuspidate pharyngeal teeth. Immediately posterior to the introvert is the trunk, which gradually increases in diameter toward its middle and posterior regions. The trunk surface is clearly marked by annuli that bear tiny setae, which appear to be long and thick at the anterior part of the trunk, small and irregular in the middle part, and arranged in distinct transverse rows in the posterior part. There is an eversible caudal projection at the posterior end of the body. The gut is straight and extends throughout the body.
