Meloidogyne paramali n. sp. (Nematoda: Meloidogyninae) and First Report of M. marylandi in
maple and yacca tree from Japan
Jianfeng Gu, Yiwu Fang, Xinxin Ma, Baolin Shao and Kan Zhuo
Meloidogyne paramali n. sp. was detected from Japanese maple trees (Acer palmatum) from
Chiba, Japan during quarantine inspections in China. This species is characterized by
second-stage juveniles (J2) with short tail length 32.2 (24?36.8) μm, finely rounded to broadly
pointed tail terminus with extremely short hyaline tail terminus 4.3 (3.0?4.9) μm; perineal
patterns of females characterized by an oval or irregular appearance, with round and low
dorsal arch, and fine and smooth striae. M. paramali n. sp. is very similar to M. mali in that
the perineal pattern has fine, smooth striae and both J2 have a short tail, but it can be
distinguished from the latter by perineal pattern of the female (lateral field distinct vs.
indistinct), shorter J2 hyaline tail terminus (4.3 [3.0?4.9] μm vs. 8.2 [4.8?12.7] μm, and by J2
tail with finely rounded to broadly pointed tail terminus, never sharply pointed vs. finely
rounded and almost pointed. The polytomous key codes of the new species are as follows:
Female: A21, B2, C32, D4; Male: A21, B3, C2, D1, E2, F2; J2: A2, B23, C43, D34, E12, F34.
Detailed phylogenetic analysis based on partial 18S, ITS, D2-D3 28S, and partial mtCOI
sequences also confirmed it as a new species, which is very close to M. mali and M. vitis and
forms molecular group VIII. M. marylandi and other Meloidogyne species detected from plants
from Japan in China are also discussed.
