Description of Laimaphelenchus shanxiensis sp. n. (Rhabditida: Aphelenchoididae) from Shanxi province, P.R. China
Laimaphelenchus shanxiensis sp. n. was recovered from the bark samples of Chinese pine tree (Pinus tabuliformis) in Shanxi province, China. The new species is characterised by having 888-1049 μm long females, the cephalic region with six labial sectors divided by ribs, stylet 11-13 μm long, the excretory pore located at the same level with, or slightly posterior to nerve ring, lateral field with four incisures, post-vulval uterine sac 54-83 μm long, vulva with a well-developed anterior flap, tail having a single stalk at terminus ending to a flat structure with 4-7 finger-like appendages in scanning electron microscopy; male spicules 20-22 μm long and two pairs of caudal papillae present. In addition, molecular phylogenetic trees inferred from the partial small subunit (SSU) and D2-D3 segments of large subunit (LSU) of rRNA genes, revealed that this nematode belongs to the Laimaphelenchus and is different from all currently sequenced species of Laimaphelenchus for their SSU and LSU markers.
期刊介绍：
Nematology is an international journal for the publication of all aspects of nematological research (with the exception of vertebrate parasitology), from molecular biology to field studies. Papers on nematode parasites of arthropods, and on soil free-living nematodes, and on interactions of these and other organisms, are particularly welcome. Research on fresh water and marine nematodes is also considered when the observations are of more general interest.
Nematology publishes full research papers, short communications, Forum articles (which permit an author to express a view on current or fundamental subjects), perspectives on nematology, and reviews of books and other media.
