- Abstract
Ektaphelenchus taiwanensis sp. n. is described and figured. The new species was isolated from pine packaging wood from Taiwan and inspected in Ningbo harbour, China, in 2009. Ektaphelenchus taiwanensis sp. n. is characterised by the lip region lacking a clear constriction separating it from the body contour, stylet relatively short (12-17 pm) and without basal knobs, and presence of three lines in the lateral field. The female post-uterine sac is less than a body diam. long, the rectum and anus are absent and the tail is conoid with a sharply pointed terminus. The male tail is conoid and has a hair-like mucron (0.5-2.5 /xm), the spicules are mitten-shaped, 12.5- 14.4 p.m long (chord) and are smoothly curved with a prominent rounded condylus, prominent pointed rostrum, and broadly rounded distal end. There are three pairs of subventral caudal papillae. Ektaphelenchus taiwanensis sp. n. is similar to E. betulae, E. josephi, E. joyceae, E. prolobos, E. propora and E. tuerkorum from which it can be separated by a combination of various morphometric and morphological characters. The D2D3 LSU and partial SSU region sequences were analysed and aligned using ClustalW implemented in MEGA version 4.0. Phylogenetic trees were generated with the Neighbour Joining (NJ) method using the Tajima-Nei distance option. The feeding habit of the new species is briefly discussed.
