- Abstract
Summary: Bursaphelenchus parayongensis n. sp. was isolated from packaging wood of a consignment from China exported to Germany. The new species is characterised by the lateral field with three lines, 9-13 μ m long stylet with small basal swellings, and the excretory pore located near the posterior part of metacorpus. The male spicules are mitten-shaped, the lamina smoothly tapers towards the distal tip. The condylus is broadly rounded, with a small dorsally bent hook, rostrum triangular with sharply pointed tip, and without cucullus. One precloacal papilla, one adcloacal pair and two postcloacal pairs of male papillae present, with the posteriormost pair forming 'gland papillae'. Bursal flap long, spade-like with posterior margin truncate or irregular. Females have a small vulval flap of 2-3 μ m long, and a post-vulval uterine sac extending for 55-77% of the vulva to anus distance. Tail cylindrical, mostly (about 70%) with a robust mucron, very short to less than 3 μ m, but occasionally tail terminus bluntly rounded, without mucron. It is similar to species in subgroup 3 of the eggersi group including B. carpini , B. clavicauda , B. cryphali and B. yongensis , but morphologically different. Detailed phylogenetic analysis based on partial 18S, ITS and D2-D3 region of 28S sequences has confirmed the status of this nematode as a new species.
