Type material. Lectotype juvenile (slide # Type-8740) deposited in the invertebrate type collection of the Department of Zoology, Swedish Museum of Natural History, Stockholm, Sweden. This specimen was described as male in the original publication. Specimen is broken, flattened and is in poor condition.

Juvenile. Body slender, cylindrical over most of its length, tapering anteriorly in anterior half of pharyngeal region and posteriorly on tail; strongly ventrally curved upon fixation. Cuticle smooth. Lateral field, body pores, epidermal glands and subcephalic, cervical and somatic sensilla cannot be observed. Anterior body end obscure. Nerve ring, hemizonid and secretory-excretory system cannot be observed. Pharynx cylindrical anteriorly, expanding posteriorly into a weak basal bulb. Reproductive system indistinct. Structure drawn and described as spicule in the original publication is an artefact. Tail elongate-conoid, straight. Caudal glands and spinneret indistinct.

Discussion. Available morphological data is not sufficient to identify this specimen with confidence. It is considered species inquirenda et incerta sedis within Nematoda.
