Bursaphelenchus paraluxuriosae sp. n. (Nematoda: Parasitaphelenchidae) in packaging wood from Indonesia

Bursaphelenchus paraluxuriosae sp. n., isolated in Ningbo, China, from packaging wood made from Alphitonia sp. (Rhamnaceae) imported from Indonesia is described. It is characterised by a slim body (a = 29-39), lateral field with four lines, excretory pore located at level of median bulb or slightly posterior, vulva at 75% of total body length, presence of a distinct vulval flap in lateral view, post-uterine branch ca two-thirds of the vulva-anus distance, female tail conical and slightly ventrally bent with irregular or roughened terminus (c′ = 4.4), spicules large and arcuate, with pointed rostrum and a cucullus, which is typical for the xylophilus group, but is reduced to a small blunt extension, and three pairs of ventro-sublateral papillae (one pair precloacal, two pairs postcloacal just anterior to the bursal flap and adjacent to each other) and a small single precloacal papilla present. The new species belongs to the xylophilus group and is most similar to B. luxuriosae. It is distinguished from other Bursaphelenchus species by morphology, ITS-RFLP patterns and sequencing results.
