-
Cuticle 1.1-1.8 um thick, outer cuticle with
transverse and longitudinal striae forming a tessellate appearance.
-
Lateral fields poorly developed, with three
longitudinal incisures, the center line deeper.
-
Lip region continuous with body contour;
six fused lips, margin of lip region with six setose labial papillae;
Oral opening with six triangular liplets.
-
Amphids with oval-shaped aperture about 5um
wide, located at level of dorsal tooth.
-
Stoma > 2x longer than wide,with two
longitudinal chambers seeparated by thorn-like dorsal tooth. Anterior
chamber larger, consisting of three regions: i) a long cheilostom, ca
twice as wide as long, isomorphic, divided into two regions, a smaller
anterior one bearing six conical rib-like plates laterally visibly
cuticularised, and a larger posterior one, barrel-shaped, as long as
wide, with refringent walls (cheilorhabdia); ii) a large gymnostom,
wider than long, anisomorphic, with very refringent walls
(gymnorhabdia); and iii) a short pro-mesostegostom, twice as wide as
long, slightly anisomorphic, longer on ventral side, bearing small
refringent rhabdia (prostegorhabdia and mesostegorhabdia). Posterior
chamber smaller, composed of i) an anisomorphic metastegostom with
a thorn-like dorsal tooth (dorsal metastegorhabdion) with opening of
dorsal pharyngeal gland; and ii) a short, slightly anisomorphic,
telostegostom with refringent walls (telostegorhabdia).
-
Neck region 17-31% of total body length.
-
Pharynx diplogastroid, pharyngeal procorpus
cylindrical, 2.5-3.9 x metacorpus length, metacorpus swollen, pharyngeal
postcorpus robust, with isthmus and basal bulb scarcely differentiated,
shorter in male.
-
Cardia conoid, surrounded by intestinal tissue.
-
Nerve ring at 56-66% of neck length, at anterior
end of isthmus.
-
Excretory pore situated at level of anterior part
of isthmus, at 57-69% of neck length..
-
Hemizonid anterior to excretory pore.
Deirid obscure.

manubrium rounded, calamus cylindroid.
-
Gubernaculum almost straight with manubrium ventrally bent and corpus
with very thin distal end.
-
Nine pairs of setose genital papillae, three precloacal and six
postcloacal (one adcloacal, one anterior subdorsal, three subventral and
one posterior subdorsal) present.
