“…The Indian species L. unituberculus Bajaj & Walia, 2000 was characterised by the tail tip bearing just one tubercle and vulva without anterior flap. The Australian species L. preissii Nobbs, 2006 andL. heidelbergi Zhao, Davies, Riley &Nobbs, 2007 were characterised by a single terminus (tubercle) on the tail, bearing many small projections.…”

Aphelenchoides xui sp. n. is described and illustrated from imported packaging wood from South Africa intercepted at Ningbo Port, China. The new species has a body length of 564-820 ßm (males) and 549-882 /xm (females). The cuticle is weakly annulated with four lines in the lateral field. The stylet is 11-13 /xm long and has small basal swellings. The excretory pore is located ca one body diam. posterior to the median bulb, or 75-100 /xm from the head. Spicules are relatively large (18-23 /xm) with apex and rostrum rounded and well developed and the end of the dorsal limb clearly curved ventrad like a hook. The male tail bears six (2 -I-2-1-2) caudal papillae. The spermatheca is axial and oblong and contains disc-like sperm. The female tail is conical, terminating in a complicated step-hke projection, usually with many üny nodular protuberances. The new species is morphologically similar to A. arcticus, A. haguei and A. parasaprophilus in Group 2 sensu Shahina, but is distinguished by spicule shape and form of the female tail terminus. Phylogenetic analysis based on SSU and partial LSU sequences revealed that A. xui sp. n. was closest to A. varicaudatus, although some species of Laimaphelenchus and Schistonchus were also included in the same branch.

“…Because B. xylophilus and relatives are easily culturable on fungal cultures (Giblin-Davis, 1993), the six species that were successfully cultured from the survey, especially those from diseased trees, were studied and sequenced. These were identified as Laimaphelenchus preissii Zhao, Davies, Riley & Nobbs, 2006b from Callitris, L. australis Zhao, Davies, Riley & Nobbs, 2006a from pine plantations and L. heidelbergi Zhao, Davies, Riley & Nobbs, 2007, Aphelenchoides sp.

Six isolates of Australian Aphelenchoidoidea, viz., Laimaphelenchus preissii from native coniferous Callitris preissii trees, L. australis from the common pine plantation trees of Pinus radiata and P. pinaster and L. heidelbergi and two morphospecies of Aphelenchoides (H1 and K1) and Cryptaphelenchus sp. (K2) from diseased P. radiata trees, were studied using light microscopy, scanning electron microscopy and phylogenetic analyses of nearly full length sequences of SSU, D2/D3 expansion segments of LSU rDNA and a fragment of cytochrome oxidase subunit I (COI). Bayesian phylogenetic analyses of SSU, LSU and COI of the six nematode species revealed that none of these Australian aphelenchoidoids was inferred to be closely related to Bursaphelenchus. The selected isolates of Aphelenchoides and Laimaphelenchus used in this study were paraphyletic in all molecular analyses. Cryptaphelenchus sp. (K2) was inferred to be sister to Seinura with SSU sequences.

During a survey for nematodes associated with conifers in northern Iran, a known species of Laimaphelenchus was found in the bark samples of Taxus baccata L. trees and is described and illustrated here as L. deconincki Elmiligy & Geraert, 1972. It is characterized by lacking a distinct labial disc on the cephalic region; having six amalgamated labial sectors of equal width, separated by pairs of well-developed ribs; three lines in lateral field; the presence of a vulva flap; vagina surrounded by a cuticularised tube in which the walls vary in thickness; the post-uterine sac 25-62 µm long; tail with a single stalk-like terminus and four pedunculate tubercles; and absence of males. L. deconincki is morphologically very similar to L. cocuccii, but differs in the shape of the vaginal musculature (more angular vs round). Additional information on morphological characters and also the phylogenetic relationships of this known species using sequences of the D2/D3 region of the 28S ribosomal RNA gene is provided and added herein.
