( Fig. 17 )

Type material. Lectotype male (slide # Type-3555) deposited in the invertebrate type collection of the Department of Zoology, Swedish Museum of Natural History, Stockholm, Sweden. Specimen is in relatively good condition with larger structures recognizable, except for the damaged anterior end.

Male. Body long, 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 damaged. Nerve ring, hemizonid and secretory-excretory system cannot be observed. Pharynx cylindrical anteriorly, expanding posteriorly into a weak basal bulb. Reproductive system diorchic, both testes outstretched. Spicules paired, symmetrical, with arcuate subcylindrical shaft and small manubrium. Gubernaculum plate-like, with small dorsal apophysis. Tail elongate-conoid. Caudal glands indistinct. Spinneret present.

Discussion. Since the anterior end of this specimen cannot be studied in detail, it is impossible to identify this species with confidence. The species is considered species inquirenda et incerta sedis within Nematoda.
