Cephalenchus intermedius sp. n. and Trichotylenchus monosexualis sp. n. (Neamtoda: Tylenchida) from Haryana, India

Two new species of nematode, Cephalenchus intermedius and Trichotylenchus monosexualis are described and illustrated. Their distinguishing features are C. intermedius L=0.65–0.79mm, a=43–71, b=5.5–8.6, c=2.5–3.2, V=55–58, stylet with anchor-shaped knobs, lateral lines four, vulval flap 3–5 pm, excretory pore anterior to hemizonid and tail filiform in both sexes. T. monosoxualis L=0.68–0.84mm, a=34–44, b=5.4–6.2, c=11–14, V=53–58, stylet=17–19μm with small backwardly directed knobs, oesophageal glandular overlap variable, vulva in flush with body contour, epiptygmata conspicuous, tail terminus usually swollen and annulated, males absent. The validity of Imphalenchus Dhanachand and Jairajpuri and Uliginotylenchus Siddiqi is discussed.
