Morphology and Anatomy:

The new species was characterised with near full-length 18S, 28S D2-D3 regions, and internal transcribed spacer (ITS) rRNA genes and mitochondrial cytochrome oxidase I (COI) gene sequences.

• Body cylindrical, ventrally arcuate in open C-shape when heat-relaxed
• Cuticle finely annulated, lateral field with three incisures.
• Stylet long and tripartite,
• Procorpus, narrow, metacorpus oval
• Pharyngo-intestinal junction immediately behind metacorpus;
• Dorsal pharybngeal gland with long overlap of intestine; DPGO in metacorpus.
• Nerve ring posterior to metacorpus; excretory pore at the level of nerve ring,
• Posterior mucron.

Female:

• Monodelphic-prodelphic; gonad outsretched to slighly reflexed, with ovary, oviduct, spermatheca, crustaformeria, uterus, vagina and post-vulval uterine sac (2-3 x VBD)
• Vulva a transverse slit
• Posterior body region conical, gradually narrowing,to a mucron-like terminus

Male:

• Common, morphologically similar to female.
• Monorchic; amoeboid sperm
• Spicules arcuate, separate, with well-developed condylus, triangular rostrum.
• Seven papilliform genital papillae
• Taile conoid, elongate to mucron-like terminus

Distribution:

Described from samples of branches and bark  of dying Pinus sylvestris in Hulunbuir City, Inner Mongolia, P.R. China. It is also reported from trees in other plantations in the region and in wood pacvking material imported into China from Japan (Gu et al., 2022).

Economic Importance:

Feeding:

 Ektaphelenchoides spp are considered parasitic and predatory to theirs insect associates.  The report of E. diversislocis from bark of dying pine trees and wood packing material suggest the need for further research on the biology and feeding habits of the genus. Insect galleries were not observed in the wood and bark from which the nematodes were collected. (Gu et al., 2022).
