syn. Clavilenchus similis, Basiroides similis

Body slender, cylindroid except at extremities.  Lip region plain, rounded, unstriated. Striae 1.2u apart except near head and on tail.  Lateral field a bright band 1/5 body width, marked by 2 fine incisures. Amphid apertures transverse, near base of lip region. Cephalic framework obscure. Spear 13u long, slender, with small round knobs, its muscles attached to a cuticular band about base of lip region.   Dorsal esophageal gland outlet 11u behind spear. Median bulb an outstanding feature, elongate-fusiform with relatively small valve and weak radial musculature.  Deirids about opposite hemizonid.  Cardia discoid.  Intestine thick-walled with narrow lumen.  Ovary outstretched, the oocytes in single file except for a short region of multiplication.  Spermatheca almost twice as long as body width, packed with spermatozoa.
Male slightly more slender than female.  Testis outstretched. Spicula arcuate, cephalated, resting on a simple, trough-like gubernaculum.  Bursa about twice as long as spicula.

Clavilenchus similis is distinguished from C. tumidus by finer striae, larger spear and ellipsoid median bulb.
