Male:

• Body long and slender, more or less spiral upon fixation.
• Lip region hemispherical, offset by a marked constriction.
• Body cutide behind constriction bulging outward due to local thickening of median layer.
• Anterior sensilla with typical 6 + 10 arrangement.
• Amphids with stirrup-shaped fovea and wide slit-like aperture
• Lateral body pores numerous, but dorsal and ventral body pores few.
• Neck region with 9-10 (paratype) to 13-17 (holotype) lateral, 1 (holotype) or 2 (paratype) dorsal and 4 (holotype) or 5 (para type) ventral body pores.
• Odontostyle long and slender, with forked base. Guiding apparatus as in Xiphidoms, i.e. with single guiding ring located far backward and without compensation sacs.
• Odontophore also comparable to Xiphidorus but flanges somewhat less developed.
• Stylet retractors present but weakly developed, their nature (double or single) cannot be determined on the available material.
• Pharyngeal retract ors as in Xiphinema and Xiphidoms.
• Slender part of pharynx not offset from enlarged part. Latter at first conical, then cylindrical.
• Dorsal gland nucleus smaller than ventrosublateral ones. Positions of outlets and nuclei as percentage of bulb length (holotype) : DO: Il, DN: 25, RSN : 48.5, LSN: 52, SO : 85.
• Pharyngointestinal junction wide and flattened, with conoid central valve. Intestine with thin wall, three or four cells in circumference. Prerectum about twice as long as the region of copulatory muscles.
• Tail dorsally convex-conoid with broadly rounded terminus, with 2-3 caudal pores.
• Reproductive system confined to posterior body half, short in para type, but longer in holotype due to large number of spermatozoa. Both testes
• Vas deferens in the holotype packed with small, highly refractive granules till opposite the anteriormost copulatory muscles, then finely granular till it merges with the very short rectum to form the cloaca.
• In the tail there are 4-5 caudal copulatory muscles.
• In addition to the paired genital papilla opposite the level of the middle of the spicules, there are seven (holotype) or six ventromedian supplements. The anteriormost of these is less developed and anterior to the first copulatory muscles; the posteriormost ventromedian supplement occurs at about two spicule lengths in front of the cloacal opening.
• There are five subventral body pores in the region of the copulatary muscles.
• Spicules stout, L-shaped with posterior dorsal thickening.

Asingle female specimen was  found later, associated with grass roots, also in Argentina (Coomans and Chaves, 1999).  The general body configurqation is similar to that of the male.
