• Cuticle  of four layers with different refraction, the outer two layers thinner, the second outer with stronger refraction, the inner layers thicker; outer layer with very fine transverse striations, innermost layer coarsely striated.
• Lip region 4-5 un high, (Figs1,angular, offset from the abody contour by a constriction; about 3 times as wide as high.
• P​(Fig.3)erioral area high, disc-like with four elevations surrounding oral aperture;  oral aperture appearing cross-like in shape in frontal view.
• Labial and cephalic papillae prominent; labial papillae button-like, each surrounded by a small ring, their openings pore-like.
• Cephalic papillae button-like; outer labial and cephalic papillae below the margin of oral field.
• Amphidial fovea cup-shaped, its aperture approximately half of lip region diameter and margin curved.
• Cheilostom a truncate cone with weakly developed walls, its anteriormost part representing a moderately cuticularised perioral ring, appearing as small perioral refractive dots.
• Odontostyle short and slender, straight, 1.2-1.6 times lip region diameter, aperture 14-16% of its length,
• Odontophore 1.2-1.6 times as long as odontostyle, with small swellings at its base.
• Guiding ring double, located at 0.8-1.0 times lip region diameter from anterior end.
• Esophagus with anterior region  enlarging gradually to an occupying 37-45% of total pharynx length.
• Excretory pore opposite the nerve ring with slightly cuticularised canal clearly visible at 100-112 um from the anterior end.
• Cardia rounded conoid.
• Tail bluntly conoid, 2-3% of body length, with numerous saccate bodies. Hyaline part 4-8 um wide or 12-25% of tail length. Two pairs of caudal pores present.
