Preserved animals up to 50 mm long, and 4 mm wide. Body margins nearly parallel; anterior end rounded, posterior end pointed. Dorsum strongly convex, ventral side slightly convex. Dorsal body surface constituted by a median stripe of orange-ochre (onequarter of body width) that passes into the black of cephalic region (one-fifth of body length), bounded on either side by a black line (1/16th) posteriorly merging with each other, externally to which is a broader white line (one-eighth), and this is externally bordered by a black stripe (1/16th), externally to which is a grey stripe (one-eighth) with dense white mottling, then bordered by a marginal thin black line (

In preserved specimen F6998, stripes were varied from faded black grey to pearl orange. Two types of eyes: a conical type contouring only anterior end; and a cup-shaped type, spreading dorsally onto the black stripes. Sensory pits simple invaginations, 40 μm deep, located ventromarginally in a single row from the very anterior tip to at least the end of the anterior fifth of the body. Relative position mouth-to-body length, 61%. Relative position gonopore-to-body length, 74%.

Testes dorsally located between supraintestinal parenchymal muscle layer and intestine; anteriormost testes (at a distance from anterior end equal to 22% of body length) behind ovarian region, posteriormost near root of pharynx. Penis bulb elongated, strongly developed, consisting of tightly packed muscle fibres variously orientated in its anterior section, while posteriorly the fibres are orientated diagonally, extending from 1 mm (holotype) anterior to penis papilla to the level of the gonopore, even more posteriorly in the dorsal body region. Diagonal fibres on the right side of the bulb run obliquely downwards to embrace ventrally the anterior portion of the female atrium; further course of these fibres could not be determined owing to tissue damage. Sperm ducts run dorsolaterally to the ovovitelline ducts. Laterally to penis bulb, sperm ducts bend anteriorly and medially, and then ventrolaterally penetrate the bulb. The ducts subsequently recurve and join to form an unpaired, sinuous sperm duct directed posteriorly (
