Amphids almost as wide as head, their sensilla lying just posterior to
base of spear extensions. Spear
5 or 6u long. Guiding ring not observed. Esophagus
at first slender, fusiform,
tapering to a narrow tube as it passes through the nerve-ring. Basal
half of esophagus enlarged by gradual expansion, glandular, with weak
radial musculature, all 5 nuclei usually visible. Cardia cylindroid,
but sometimes compressed to a disk by fixation. Intestinal cells
hyaline with few scattered granules. Prerectum length 4 or 5 times
body width. Vulva
transverse. Anterior uterine branch shorter than body diameter. Ovary
reflexed halfway or more to vulva, often pressed forward by developing
ova. At flexure of ovary is a pouchlike organ visible in young females
in which are several bodies which which may be syngonic spermatozoa.
Male body similar to that of female. Testes well-developed
with great numbers of spermatozoa. Spicula rather angular, with tiny
lateral guiding pieces. Copulatory musculature very obscure.
