description
Dimensions of 20 females: L = 1.03 - 1.31 mm; a = 42 - 56; b = 4.1 - 5.1; c = 2.7 - 3.0; V = 5 - 941 - 443 - 7. Cuticular annulation broad, 1.8 JJ. on middle ofbody, but shallow and mostly indistinct; the cuticle may even appear smooth over large stretches of the body. Amphids opening through transverse slits 4 \ x long, located at 32 - 38 fx or 2.5 - 3.0 head widths from the anterior end. Mouth cavity 11 - 15 jx deep. Length of the longer cephalic setae 8 - 11 \ L. Cardia very large. Vulva inconspicuous, vagina with sclerotization resemblingthat of Trichodorusprimitivus. Dimensions of an intra-uterine egg: 75 X 19 jx. Gonads paired, opposed. I never found developing eggs in both gonads simultaneously; usually the gonad containing one is larger and more distinct than the other; thus the gonads are in most specimens asymmetrically developed. Vulva a transverse slit. Tail measuring 22 - 29 anal body widths, with spinneret tube 1.2 \ L long. Scattered submedian setae are present all over the body. Very numerous and dominant in sample 36. Found also in samples 7, 8, 11, 21, 31, 37, 41, 57 / 58 and 69.
