摘要： Longidorus zhengi n. sp. was recovered in the rhizosphere of Quercus aliena in China. The new species is characterised by medium-length females (3.2-4.0 mm), lip region slightly offset, anteriorly flat and separated from the rest of the body by constriction, funnel-shaped amphidial pouches, a simple guiding ring located at 57.0-60.0 mu m distance from the anterior end, stylet composed of a moderately long odontostyle (108.0-139.0 mu m) and weakly developed odontophore (56.0-68.0 mu m), 61.0-74.0 mu m long pharyngeal bulb, well-developed offset cardia, and a short conical tail with widely rounded terminus. The species has four juvenile developmental stages (J1-J4) and no male was found. The matrix codes of the new species are: A45-B23-C5-D2-E1-F2-G1-H1-I1-J1-K5. The new species was molecularly characterised using ITS1 and 28S D2-D3 rRNA gene sequences. The phylogenetic analyses placed L. zhengi n. sp. with several species described from the mainland of China, which were clustered with L. litchi, L. diadecturus and L. juglans.
