摘要

报道了宁波港从韩国松木包装材中分离得到的一种韩国松壳线虫(Aphelenchoides koreanus n.)。雌性体长603 (511-687)μm，体型粗壮(a = 24.4(21.9-26.7))。外侧野有四个切口。纤细的花柱长12.3 (11.7 ~ 13.4)μm，基部有小突起。排泄孔位于神经环后方。半隔腺紧靠排泄孔后，但有时不可见。阴道没有硬化，外阴有突出的嘴唇，没有皮瓣。脓液发育良好，约占外阴至肛门距离的30.6-41.9%。尾部近圆柱形，末端粗圆或稍尖，总是有一个很短的绒毛或小突出，约1 μm长。男性缺席。该新种隶属于麻蝇属(Aphelenchoides)第1群。基于ITS序列的系统发育分析证实了其新种的地位。

Aphelenchoides koreanus n. sp. (Tylenchina: Aphelenchoididae) found in packaging wood from South Korea

Aphelenchoides koreanus n. sp. isolated in Ningbo Port, P.R. China, from Pinus packaging wood from South Korea is described. It is characterised by the female length of 603 (511-687) μm, stout body shape (a = 24.4 (21.9-26.7)). The lateral field has four incisures. The slender stylet is 12.3 (11.7-13.4) μm long and has small basal swellings. The excretory pore is located posterior to the nerve ring. The hemizonid is immediately posterior to excretory pore, but sometimes invisible. The vagina is not sclerotised, and the vulva has strongly protruding lips and lacks a flap. The PUS is well developed and forms ca 30.6-41.9% of the vulva to anus distance. Tail sub-cylindrical, terminus bluntly rounded or slightly pointed, always bearing a very short mucron or a small projection, about 1 μm long. Males absent. The new species belongs to the group 1 category of Aphelenchoides species sensu Shahina. Phylogenetic analysis based on ITS sequences confirmed its status as a new species.

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.
