Abstract

Xiphinema bricolensis n.sp. and Xiphinema pacificum n.sp. are described and illustrated from British Columbia vineyards. Xiphinema bricolensis differs from X. occiduum by the longer odontostyle, longer tail, smaller a value, and larger c′ value. It differs from X. thornei by the smaller c value, larger c′ value, longer tail, and greater anal body width. Xiphinema pacificum is closely related to X. californicum but differs by the longer tail, larger c′ value, longer odontophore, more posterior vulva, and position of the caudal papillae.
