Longidorus leptocephalus Hooper, 1961

Morphology and Anatomy:

		Cuticle 2.9 ï¿½ 0.3 (2.6ï¿½3.2) um thick at mid body. Lip region narrow and rounded, slightly offset Amphidial pouches asymmetrically bilobed at base. Guiding ring single, at 2.6ï¿½2.9 times lip region diameter behind anterior end. Odontostyle 1.3ï¿½1.7 times as long as odontophore; odontophore with slight basal swellings. Pharynx extending to a terminal pharyngeal bulb Glandularium 67.0ï¿½87.0) um long. Cardia conoid-rounded. Vulva at about middle of the body. Genital system amphidelphic, anterior and posterior genital branches almost equally developed. Sperm cells not detected inside uterus or oviduct. Tail conical, dorsally convex, ventrally concave to flat with bluntly rounded terminus. Males not seen Ref: Clavero-Camacho et al. (2022)

Has been implicated along with L. attenuatus and L. elongatus in carrying Docking Disorder of sugarbeet in England.
The nematode is probably a vector of plant viruses; viruses have been detected in the body but definitive tests of transmission have not been performed (Clavero-Camacho et al., 2
