Body tapering anteriorly in pharyngeal region and posteriorly on tail; straight upon fixation, curved ventrad only in posterior part in males. Maximum body diameter at vulva in female; male body more cylindrical. Cuticle annulated; annuli 1.4–2.1 µm wide at mid-body, without ornamentation; annulation at level of amphid same as annulation along rest of body. Lateral field present, consists of single alae (two incisures), 1.5–2 µm wide at mid-body; arising some distance posterior to amphid (metacorpus) and extending posteriorly to anterior 2/5th of tail. Prominent body pores in sublateral position at both sides of lateral field present, arising from oval lateral epidermal gland cells; several pairs of body pores are present along pharyngeal region; several body pores scattered over rest of body. Anterior-most body pore located posterior to amphid, at level of procorpus. Labial region rounded, continuous with body contour, lips fused. Inner and outer labial sensilla indistinct. Cephalic sensilla papilliform. Subcephalic and cervical sensilla and ocelli absent. Amphidial fovea elongated, an inverted Ushaped, inner borders often visible; located at level of posterior part of stoma and anterior part of procorpus. Nerve ring surrounding pharynx at level of anterior part of isthmus. Hemizonid not seen. Secretory-excretory system indistinct. Buccal cavity uniformly tubular: cheilostom and gymnostom short, undifferentiated; stegostom tubular, with uniformly thickened lumen. Pharynx muscular, cylindrical anteriorly, with weakly developed pyriform basal bulb; valvular apparatus absent. Anterior cylindrical part of pharynx subdivided by breaks in muscular pharyngeal tissue into cylindrical procorpus, cylindrical metacorpus and narrow isthmus. Pharyngeal glands and their orifices indistinct. Cardia cylindrical, its posterior part embedded in intestine. Tail almost similar in shape in both sexes (more curved ventrad in male), elongate-conoid in its proximal part (equal to 38–41% of total tail length in females and 29% in male), subcylindrical in distal. Three caudal glands present, nuclei incaudal. Spinneret functional.

Reproductive system diorchic; anterior testis outstretched, located on right hand side of intestine; posterior one reflexed. Spicules paired, symmetrical, with arcuate cylindrical calamus and ovoid manubrium. Gubernaculum 6 µm long, plate-like, with caudal apophysis 8 µm long. Accessory apparatus composed of one midventral precloacal papilliform sensillum located at level with spicules, two midventral tubular supplements extending for 62 µm from cloaca towards anterior end; alveolar supplements absent. Tubular supplements weakly arcuate in shape, with blunt tips. Posterior-most tubular supplement 40 µm anterior to cloaca, anterior to spicules. Sublateral precloacal sensilla absent, four caudal sensilla arranged in two subventral pairs. Four small papillae located at the posterior edge of lateral field, one subventral pair and one subdorsal pair.

Reproductive system didelphic, amphidelphic; ovary branches reflexed antidromously. Anterior genital branch 45–69 µm long (equal to 6–9% of total body length), located on right-hand side of intestine (n=4), posterior genital branch 64–86 µm long (equal to 9–12% of total body length), located on left-hand side of intestine (n=4). Oviduct a narrow tube. Two offset, oval, sac-like spermathecae located on each (right and left) side of each (anterior and posterior) gonoduct. Spermathecae and oviducts filled with oval spermatozoa. Uterus a short tube. Vagina straight, 0.3 times vulval body diameters long;
