Description
Female. Body cylindrical, almost straight upon fixation, tapering slightly anterior to base of pharynx, posteriorly ending in long filiform tail. Cuticle smooth, 2–3 µm thick at mid-body and 2.5–3.0 µm on tail. Lateral chord about one-fifth of body width at mid-body. Lateral, dorsal and ventral body pores indistinct. Lip region narrow rounded, continuous, about one-third of body width at neck base and about twice as wide as high. Amphids cup-shaped, their aperture about two-thirds of the lip region width wide. Odontostyle asymmetrical, 0.60–0.66 times lip region width long; its aperture about one-third of its length. Guiding ring thickened, distinctly sclerotized, at 0.42–0.46 times lip region width from anterior end. Odontophore simple, linear, 2.6–2.7 times the odontostyle length. Nerve ring at 46–47% of neck length from anterior end. Anterior part of pharynx very slender; expanded portion surrounded by a thin sheath (not spiral) occupying about 27–29% of total neck length. Cardia elongate, conoid, about half of the corresponding body width long. Pharyngeal gland nuclei located as follows. D = 75–78; AS 1 = 24–26; AS 2 = 52–56; PS1 = 69–71; PS2 = 70–74. Genital system monodelphic–opisthodelphic; anterior branch represented by a uterine sac, 1.2–1.8 times corresponding body width long. Posterior branch well developed, still relatively short; ovary reflexed, measuring 48–60 µm with oocyte arranged in single row except near tip. Oviduct joining ovary subterminally, measuring 88–92 µm in length. Sphincter present at oviduct–uterus junction. Uterus an undifferentiated tube, measuring 30–35 µm in length. Vulva a transverse slit. Vagina with thick cuticular walls, about one-half to one-third as wide as corresponding body width deep; pars proximalis vaginae 10–11 µm long with straight walls encircled by circular musculature; pars refringens vaginae absent; pars distalis vaginae measuring 8–9 µm with curved wall. Prerectum 3.0–3.6 anal body widths long. Rectum 1.5–1.6 times anal body width long. Tail long filiform, about 15–22 anal body widths long. Caudal pores two on each side.
Male. Similar to female in general morphology except more ventrally curved in posterior region because of presence of copulatory muscles. Supplements, an adanal pair and three to four spaced ventromedians. Spicules dorylaimoid, about 1.7 times anal body widths long. Lateral guiding pieces about one-third of spicule length. Prerectum 3.6–4.2 anal body widths long. Tail long filiform, about 13–16 anal body widths long, and with a pair of caudal pores on each side.
Type habitat and locality
