Diagnosis (from Raski and Geraert, 1985)
Slender nematodes, 'a' values range from 37-93; almost straight when fixed and mounted in glycerine. Cephalic region high, smooth, narrowed dorso-ventrally; amphid apertures long slits beginning near small oral cap or plate extending longitudinally to posterior margin of smooth cephalic region. Sclerotization delicate; stylet slender but distinct with small knobs (except in L. elegans knobs not visible); dorsal gland oriface near knobs (except in L. elegans appears to enter base of stylet). Median bulb slender, fusiform (spindle-shaped); valvular apparatus variously developed; isthmus very slender; posterior bulbar region pyriform to elongate. Spermatheca rounded to oval; uterine cells probably in quadricolumellar arrangement; vagina curved anteriorad (L. leptosoma) or perpindicular. Vulval opening with lateral membranes; post-uterine sac short. Tail long, becoming almost filimentous. Lateral field variable; lacking (L. leptosoma), a narrow band forming two lines (L. filicaudata) or two distended tube-like bands forming four lines. Males similar to females; caudal alae leptoderan, short.
