First report of Xiphinema brevicolle Lordello et Costa, 1961 (Nematoda, Longidoridae) in Japan.

ABSTRACT: Mixed populations of Xiphinema americanum-group species were detected from a root zone soil sample of Japanese holly, Ilex crenata, during a survey for plant-parasitic nematodes of commercial ornamental plant nurseries in Chiba Prefecture, Japan. From the result of the morphological study, the species were identified as Xiphinema brevicolle and Xiphinema sp. This is the first record of Xiphinema brevicolle in Japan. Morphometrics of Xiphinema brevicolle generally agree with those of the type specimens and the topotype specimens. Xiphinema sp. morphometrically resembles Xiphinema paramonovi except for tail length. The mitochondrial COI region, the nuclear 18S rDNA and the nuclear large subunit rDNA D2/D3 region of the species were sequenced and compared in the molecular study. For the COI r
