Body curved gently ventrad, rarely to open C. Tapering anteriorly from base of stylet, psoteriorly approximately from ½ body width anterior to vulval area, more acutely posterior to vulva. Body annules smooth, anastomoses rare. Cephalic region truncate with 2 annules not set off from rest of body, distinct from body annules because they are rounded, direct laterally and have thin cuticle. Body annules retrorse with angular appearance. Cephalic sclerotisation distinct. Stylet short, flexible, stylet base anchor-shaped. Excretory pore not observed. Vulva distinct, open, with 2 rounded lips protruding from body contour about as far as body annules. Vagina straight to slightly curved, about 2/3 body width long, angled anteriad. Spermatheca subspherical, offset, ventral, filled with small sperm. Tail conical. Tail terminus with 2 distinct annules that look fused. Anus generally visible as slightly shorter annule halfway along postvulval area.
