摘要: 对分离自宁波马尾松的Devibursaphelenchus hunanensis 进行重新描述,其鉴定特征如下:侧区有3条侧线,较长的口针(雄虫为 15~20 μm,雌虫为18~22 μm),无基部球;无阴门盖,非常短的后阴子宫囊;雌虫直肠和肛门模糊或者不存在;交合刺直线长16~19 μm,远端有盘状突;从腹面观,存在清晰的交合伞;具捕食性。并对其rDNA的SSU区、ITS1/2区、D2D3 LSU区和部分mtCOI基因测序并提交NCBI。结合形态和分子数据,将D. hunanensisD. eproctatus的模式标本进行比较,发现二者特征高度吻合,D. eproctatusD. hunanensis的同物异名。

Abstract: Devibursaphelenchus hunanensis isolated from Pinus massoniana is redescribed. The identification features are as follows: three incisures in the lateral field; relatively long stylet (about 15-20 μm and 18-22 μm for males and females) with wide lumen and without basal knobs and vulva flap, and very short postuterine sac. Female rectum and anus indistinct or disappear. The spicules are in medium size, 16-19 μm long in chord, and the arcuate with a terminal cucullus. There is a distinct bursa flap in ventral view. D.hananensis is predatory. The partial SSU region, the ITS1/2 region, the D2D3 LSU region of rDNA and partial mtCOI gene were sequenced and deposited in the GenBank database. With the morphological and molecular data, the isolate was compared with type specimens of D. hunanensis and D. eproctatus. Their features are highly consistent, thus D. hunanensis and D. eproctatus is regarded as synonymous of D. hunanensis.
