文摘

A new plant nematode species named Paratylenchus guangzhouensis n. sp. was extracted from the soil associated with Bambusa multiplex in Guangzhou, Guangdong Province, China. The new species is characterized by having the female with a small body 217–247 μm long, a slender stylet 43–49.5 μm long, head rounded without distinct submedian lobes, amphid openings large, and bow-tie like in shape, oral opening with two prominent ridges laterally, lateral field with three distinct lines, small lateral vulval flaps and tail tip finely rounded to bluntly rounded; male with a 237.5 μm long body, spicules 15.5 μm long, stylet lacking and pharynx degenerate; and the fourth-stage juvenile with a stylet. The internal transcribed spacer sequences of ribosomal RNA (ITS rRNA) gene of the new species were amplified and sequenced, and a phylogenetic tree inferred from the ITS rRNA gene is given in this study.KeywordsParatylenchusMorphologyMolecularITS rRNA geneNew species
