The new species is characterized by its body length (1.56\u20131.81 mm in females and 1.39\u20131.57 mm in males), lip region offset by weak constriction and wider than adjacent body (11\u201314 \u03bcm), odontostyle 17\u201320 \u03bcm long, neck length 312\u2013434 \u03bcm, vulva longitudinal (V = 42.2\u201346.5), uterus well-developed and with Z-differentiations, tail long (219\u2013237 \u03bcm, <jats:italic>c<\/jats:italic> = 6.9\u20138.3, <jats:italic>c\u00b4<\/jats:italic> = 8.2\u201310) in females, short and convex-conoid with blunt terminus (19\u201322 \u03bcm, <jats:italic>c<\/jats:italic> = 68\u201372.5, <jats:italic>c\u00b4<\/jats:italic>= 0.77\u20130.84) in males, spicules 40\u201345 \u03bcm long, and 18\u201320 contiguous ventromedian supplements with hiatus.
