-
Moderately slender (a = 20-24) nematodes, small to medium size,
0.93-1.10 mm long.
-
Body cylindrical, tapering towards both ends
-
Cuticle dorylaimid, two-layered, 3-5 μm
thick in anterior region, 3.5-7 μm
at mid-body and 7-9 μm
on tail, outer layer thin.and with distinct radial striation.
-
Lateral chord occupying ca one-fourth
of mid-body diam. Body pores obscure.
-
Lip region offset by variably distinct constriction, cap-like,
2.1-2.2 times as wide as high and one-third of body diam. at neck
base, lips mostly amalgamated, with slightly protruding labial and
cephalic papillae.
-
Amphidial fovea cup-like, its aperture occupying 1/2 to 2/3 of lip
region diam.
-
Odontostyle typical of genus, 1.0-1.5 times lip region diam. long,
dorsal stiffening piece covering entire dorsal arm, aperture short,
1/8 of total length. Guiding ring simple.
-
Odontophore 0.4-0.7 times odontostyle length, with distinct basal
knobs 3-6 μm
broad.
-
Esophagus
with a slender and weakly muscular anterior region and a nearly
pyriform basal bulb occupying 12-21% of total esophagus length.
-
Cardia short, hemispheroid, 3-4 × 7-11 μm.
-
Intestine lacking any differentiation. Prerectum 1.2-2.1 and
rectum 0.9-1.3 anal body diam. long. Caudal region short and rounded
to conoid, visibly more straight along ventral
Female:
-
Genital system mono-opisthodelphic. Anterior genital branch reduced
to a simple uterine sac. Posterior ovary reflexed for two-thirds of
distance to vulva, often reaching beyond oviduct-uterus
junction
-
Oocytes
arranged first in two or more rows, then in a single row.
-
Vagina perpendicular to body axis, extending inwards for 38-55% of
body diam., with pars
proximalis 9-17
× 13-18 μm
long and surrounded by weak circular musculature, and pars
distalis 2.0-3.8 μm
long.
-
Vulva a transverse slit.
