Ektaphelenchoides sylvestris sp. nov. is described and illustrated. The new species was recovered from the galleries of bark beetles from a dead Pinus sylvestris L. tree and characterized by females with 644–843 µm long body, lip region 7.5–9.0 µm wide, separated from the rest body with a shallow constriction, stylet 18–23 µm long, excretory pore 72–85 µm far from anterior end, postuterine sac short, 5–11 µm long and male absence. By having a short postuterine sac, the new species comes close to four known species of genus namely E. attenuata, E. musae, E. pini and E. wintert.
