- Abstract
Aphelenchoides xylocopae n. sp. is described and figured. The new species was isolated from the Japanese large carpenter bee, Xylocopa appendiculata circumvolans, and reared on a lawn of Botrytis cinerea. Specimens were collected from a 2-week-old culture on the fungus. The new species has a body length of 514-638 μm (males) and 532-674 μm (females). The cuticle is weakly annulated and there are three lines in the lateral field. The stylet is 10-11 μm long and has small basal swellings. Spicules are large (23-28 μm) and strongly arcuate. The male tail bears six (2 + 2 + 2) caudal papillae and is mucronate. The female tail is tapered to a pointed, amucronate or mucronate, terminus. The new species belongs to the Group 2 category of Aphelenchoides species. Cultured nematodes were used for sequencing the partial (ca 1 kbp) cytochrome oxidase subunit I of mitochondrial DNA and partial (ca 900 bp) small subunit ribosomal DNA for comparison with the sequences deposited at GenBank. The DNA sequences of A. xylocopae n. sp. were close to those of other Aphelenchoides and Bursaphelenchus species in the database, but the precise phylogenetic status of the new species could not be determined because of the limited sequences available for Aphelenchoides species.
