It is characterized by its body 1.92-2.40 mm long, lip region offset by constriction and 17-19 ?m wide, odontostyle 16-19 ?m long with aperture occupying less than one-third (27-30%) its length, neck 428-690 ?m long, pharyngeal expansion 369-390 ?m long or occupying 54-56% of total neck length, female genital system amphidelphic, uterus bipartite and 162-218 ?m long or 2.3-3.5 times as long as body diameter, pars refringens vaginae well developed, V = 54-57.5, vulva longitudinal, prerectum bearing a blind sac, tail conical with rounded tip to conoid (25-36 ?m, c=60-69, c'=0.5-0.9), spicules 68-72 ?m long, precloacal pair of supplements far (22-27 ?m) from cloacal aperture, and 13-17 shortly spaced ventromedian supplements with hiatus. The new taxon is compared in depth to its relatives in Crassolabium as well as other similar species of Aporcelaimellus and Amblydorylaimus.
