Ektaphelenchoides factum n. sp. in Pinus taeda from the USA and E. pini in Pinus koraiensis from China

What is it about?

Ektaphelenchoides factum n. sp., s isolated from log sample of Pinus taeda imported from the USA is described. It is characterised by the lateral field with three incisures, stylet distinctly tripartite, females have a vulval flap, anus and rectum indistinct, tail (posterior part of body) filiform. Male having arcuate and 21.5 (19.4-22.9) μm long spicules. The lamina of the spicule is smoothly curved to distal end, condylus well developed with broadly rounded tip, rostrum triangular with finely rounded tip and cucullus absent. Male tail arcuate and conical with terminus bearing a sharply pointed tip. The new species is different from other Ektaphelenchoides species by having a vulval flap. Molecular characterization and phylogenetic studies also supported its unique status. In addition to that, a Chinese native population of E. pini detected in Pinus koraiensis branches from Liaoning province, China is described.
