Zusammenfassung: | n. sp. was detected from Japanese maple trees (
) 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.
n. sp. is very similar to
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
. indistinct), shorter J2 hyaline tail terminus (4.3 [3.0–4.9] μm
. 8.2 [4.8–12.7] μm, and by J2 tail with finely rounded to broadly pointed tail terminus, never sharply pointed
. finely rounded and almost pointed. The polytomous key codes of the new species are as follows:
: A21, B2, C32, D4;
: A21, B3, C2, D1, E2, F2;
: 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
and
and forms molecular group VIII.
and other
species detected from plants from Japan in China are also discussed. |
