- Body long and rather slender, spiral upon fixation.
- Cuticle 4 (3.5-4.5) ,urn thick at mid-body, thicker near
anterior end and 13.8 (12-l 7),um thick at tail tip with three
main layers; with very fine transverse striations at the surface
(SEM) and inner radial striations which are most prominent in the
tail region.
- Lateral chord 20.3 (18-24) ,um wide at mid-body, i.e. 24.4
(20.5-30) % of the corresponding body width.
- Lateral body pores numerous, but dorsal and ventral body pores
few and restricted to the odontostyle region and neck region
anterior to bulb, respectively; 7 (5-9) dorsal, 11.3 (10-13)
ventral and 16.6 (15-18) lateral pores in the neck region.
- Lip region hemispherical to slightly flattened anteriorly,
offset by a marked constriction. Body cuticle behind constriction
bulging outward due to thickening of median layer.
- Anterior sensilla 6 + 10, appearing as minute pores under SEM.
- Amphids with stirrup-shaped fovea and wide slit-like opening
occupying 70-80% of the width at the constriction.
- Odontostyle long and slender, with forked base. Guiding ring
single, located posteriorly.
- Odontophore with weak, but clearly visible flanges. Pharyngeal
retractors well developed.
- Slender part of pharynx not offset from enlarged part; latter
at first conical, then cylindrical.
- Dorsal gland nucleus smaller than ventrosublateral nuclei.
Positions of outlets and nuclei as percentage of bulb length (n =
3) : DO : DN: DO-DN: 10.1 ( 9. 1-10.7) 23.5 (20.8-26.9) 13.5
(11.7-16.2) LSN: RSN: SO: 51.3 (45.5-54.7) 51.7 (46.5-54.7) 75.0
(73.1 -76.6)
- Pharyngo-intestinal junction wide and flattened.
- Tail dorsally convex-conoid with bluntly rounded terminus,
without blind canal.
Female:
- Two caudal pores at each side in all females and one adana!
pore at each side in two females and at one side in one female.
- Female reproductive system didelphic, amphidelphic. Different
parts variable in length according to stage of maturation.
- Uterus with rhomboid crystalloids mainly in its distal part;
without pars dilatata.
- Sperm may be present throughout the uterus, it is stored in
the pars dilatata oviductus (functional spermatheca); small
numbers may be encapsulated in the slender part of the oviduct.
Proximal part of both uteri forming a poorly defined ovejector.
- Vagina 43 (40-46) ,urn long, extending inward to 49-55% of the
corr.esponding body width.
- Vulva a transverse slit.
Male:
- Similar to females in most respects except for sexual
characters. Body more curved in posterior region.
- Odontostyle base less clearly forked than in females.
- Tail with slightly concave ventral side; with 2-3 caudal pores
at each side and one adana! pore at each side or at one side of
tail.
- Reproductive system typical for genus, with 4-5 ejaculatory
glands; 60-64 copulatory muscles and ten (4 + 6) accessory
copulatory muscles; 10-11 ventromedian supplements and 6-8
subventral body pores in the region of the copulatory muscles.
- Spicules stout, ventrally curved; lateral guiding pieces
rod-shaped.
