( Fig. 12 )

Type material. Lectotype juvenile (slide # Type-3554) deposited in the invertebrate type collection of the Department of Zoology, Swedish Museum of Natural History, Stockholm, Sweden. Specimen is in poor condition.

Juvenile. Body long and slender, cylindrical over most of its length, tapering anteriorly in anterior half of pharyngeal region and posteriorly on tail; strongly ventrally curved upon fixation, especially so along tail. Lateral field, body pores, epidermal glands and subcephalic, cervical and somatic sensilla cannot be observed. Labial region rounded, continuous with body contour. Inner and outer labial sensilla indistinct. Cephalic sensilla setiform. Amphid indistinct. Ocelli absent. Nerve ring, hemizonid and secretory-excretory system cannot be observed. Oral opening terminal. Onchiostyle-like structure visible but poorly preserved. Pharynx poorly preserved. Reproductive system indistinct. Tail short-conoid, with broadly rounded terminal part, ventrally curved. Spinneret absent.

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