Abstract
A species of Trichotylenchus nematode was isolated from the rhizosphere of banana root in Leizhou City, Guangdong Province, China. The species assumes the following characteristics: open C-shaped body; head offset from body; lateral field with three incisures, pharyngeal and tail regions irregularly areolated; stylet 18.6-20.7 µm long; pharyngeal gland not extending over intestine; fibrous tissue present in the intestine; post-anal intestinal sac present; elongate-subcylindroid tail, bluntly conoid terminus, lack of striations, and containing 34-44 annuli. In addition, scanning electron microscopy was used to elucidate some morphological details, but only some juveniles were observed. Partial 18S rRNA, ITS, and 28S D2-D3 expansion sequences were amplified with universal primers and deposited in GenBank under accession numbers ON622716, ON622717, and ON622714, respectively. Here, this species was identified as T. dispersus [(Siddiqi & Sharma, 1995) Geraert, 2011].
