          Uliginotylenchus Siddiqi, 1971

Type species of the genus: Uliginotylenchus ulignosus (Siddiqi, 1970) Siddiqi, 1971
   

Synonyms:
     Sometimes considered a synonym of Tylenchorhynchus or Trichotylenchus

The genus Uliginotylenchus Siddiqi, 1971 was erected to accommodate those species of Tylenchorhynchus with an areolated lateral field with three incisures.  Fortuner and Luc (1987) and Maggenti et al. (1988) thought that these species should be in Trichotylenchus Whitehead, 1960. The main differences between Uliginotylenchus and Trichotylenchu were the different cephalic morphology and that in Trichotylenchus the esophageal glands extend over the intestine.while in Uliginotylenchus they do not. Xu et al (2011) support the validity of Uliginotylenchus as a genus. While Xu et al placed the genus in the family Belonolaimidae, most current opinion would place it in the Dolichodoridae or Telotylenchidae.

Per Geraert, 2011, the genus Trichotylenchus is now generally used for all "Tylenchorhynchus-like" species with 3 lines in the lateral field and no longitudinal lines outside the lateral field.
