General— Small nematodes, cuticular surface with transverse striations. Leaf crown elements 8 in number, recurved at tips. Cephalic end with cephalic collar extended laterally, with 2 amphids and 4 submedian cephalic papillae, projecting anteriorly from perioral cuticle. Buccal capsule wider than deep. Papillae consisting of 2 segments, proximal segment rectangular, 4.6 long, distal segment ovoid, 7.2 long. Nerve ring anterior 1/3, deirid posterior to nerve ring, excretory pore at mid-length of esophagus. Esophagus unornamented, short, wider at posterior end.
Male (n=14)—Body length 5.242 (3.902 –5.880), maximum width 265 (260–340). Buccal capsule 42 (30–50) wide, 24 (18–28) long. Nerve ring, deirid, and excretory pore from cephalic end 266 (200–320), 315 (301–388), 493 (433–670) respectively. Esophagus 578 (520–640). Bursa short, lobes indistinct. Ventro-ventral and latero-ventral rays apposed, long, slender, reaching bursal margin; externo-lateral ray stout, divergent, shorter than other lateral rays reaching bursal margin; medio-lateral and postero-lateral rays apposed, slender, reach bursal margin; externodorsal ray robust, arising adjacent to lateral trunk, not reaching bursal margin; dorsal ray broad at origin, becoming thinner after lateral branchlets arise at mid-length, and at the tip, not reaching bursal margin. Spicules slender, long, almost 1/3 of body length, transversely striated, length of spicules 2.17 (2.00–2.41) mm. Gubernaculum small, trapezoidal in shape, 30 (23–48).
Female (n=20)—Body length 5.65 (4.96–6.58) mm, maximum width 321 (260–410). Buccal capsule 52 (43– 65) wide, 30 (23–38) long. Nerve ring, deirid, and excretory pore from cephalic end 277 (225–340), 320 (273–408), 498 (450–650), respectively. Esophagus 611 (410–750) long, 9.25 % of BL. Vulva close to anus, 242 (220–290) from tip of tail. Vagina vera 844 (722–930) long, recurrent, vagina uterina long and slender 238 (212–270), vestibule and sphincter almost the same length. Tail short, decreasing at mid length, ending in conical tip, 146 (115–210) long. Eggs thin shelled, elongated 72 (68–75) long, 43 (35–50) wide.
