Abstract

Bursaphelenchus parantoniaen. sp. isolated in Ningbo, China, from packaging wood made ofPinussp. imported from Belgium, is described. It is characterised by a slim body (a = 32.6-51), lateral field with two lines, excretory pore locatedcaone metacorpal length posterior to median bulb, spicules stout and arcuate with triangular rostrum and flattened cucullus, and seven caudal papillae arranged as a single midventral precloacal papilla, one adcloacal pair and two postcloacal pairs. The vagina is inclined anteriorly, a vulval flap is present, the post-uterine branch extends for more than half of the vulva-anus distance, and the female tail is conical with a hyaline region and bluntly rounded terminus. Phylogenetic analyses showed thatB. parantoniaen. sp. clusters with thehylobianum-group and appears close toB. antoniae,B. chengi,B. hylobianumandB. niphades. The new species is distinguished from these species by morphology, ITS-RFLP patterns and molecular characters.
