- Abstract
Two Sheraphelenchus populations were isolated from pine wood packaging from Italy and onion bulbs from South Korea at Ningbo Port, China, respectively. The former, on the basis of morphology and molecular sequencing, is described as S. parabrevigulonis n. sp., which is characterised by a stylet length of 11 µm, three lines in the lateral field, excretory pore at level with, or slightly posterior to, nerve ring, V = 93.1, and spicules with long condylus and membrane-like rostrum in a shallow triangular shape. The species from onion, also on the basis of morphology and sequence data, was identified as S. sucus, which is characterised by a stylet length of 13 µm (erroneously stated to be ca 6 µm in the type description), excretory pore at level of, or posterior to, median bulb, and V = 80.9. The phylogeny trees based on rDNA 18S, 28S D2-D3 and ITS1/2 sequences revealed that S. parabrevigulonis n. sp. and S. sucus clustered into a clear clade and grouped with Bursaphelenchus species. The study enriched the taxonomic information of Sheraphelenchus and confirmed its status as an independent genus.
