Description of Xiphinema pupureum n. sp. (Nematoda: Longidoridae), a new Xiphinema americanum group species detected from the rhizosphere of Ilex purpurea from Japan

What is it about?

Xiphinema purpureum n. sp was recovered in the rhizosphere of holly (Ilex purpurea) imported from Japan. The new species is characterized by moderately long females 2267 (2115–2550) μm; round lip region slightly offset from the rest of the body; 103.5 (98.5–109) μm long odontostyle, two equally developed genital branches; vulva located at 54.1 (51.6–57.1)% of the body; tail 30 (24.3–33.4) μm long with a broadly rounded terminus. Male absent. Four juvenile developmental stages are present. The polytomous key is as follows: A4/5, B2/3, C1/2, D2/3, E3, F1, G1, H2, I1/2/3. The new species was molecularly characterized using near full length of 18S, ITS, 28S D2–D3 regions of rRNA genes sequences and mitochondrial DNA cytochrome oxidase subunit I.
