Description of Bursaphelenchus irokophilus n. sp. (Nematoda: Aphelenchoididae) isolated from Milicia excelsa (Welw.) C.C. Berg wood imported into Italy from Cameroon.

Summary: A new species of Bursaphelenchus , extracted from unprocessed logs of Milicia excelsa from Cameroon and arriving in the port of Leghorn, Tuscany, Central Italy, is described. Bursaphelenchus irokophilus n. sp. is based upon morphological and molecular characters and is characterised by the two-lined lateral field, mitten-shaped spicule possessing cucullus and well-developed and slightly dorsally curved condylus with narrowly rounded tip, female vulva with side flap, and long, smoothly tapering and strongly ventrally recurved female tail. The new species belongs to the abietinus -group and is similar to, but distinguished from, B. abietinus and B. rainulfi by the position of secretory-excretory pore, longer and slender female tail and some morphometric values. In addition, the phylogeny based on SSU and D2-D3 LSU regions shows that this species belongs to the abietinus -group, the relationship among the species of this group being discussed.
