Three new species of genus Aphelenchoides have been described from Haryana, India. A. brushimucronatus sp.n. (from mushroom beds) has females with L = 0.43–0.51 mm; a = 29–32; b = 8.3–9.8; b′ = 4.2–4.6; c = 11–13; c′= 4.8–5.5; stylet = 13 μm; V = 62–73; post vulval uterine sac = 31–47 μm long; lateral lines 4. Males common, dorsal limb of spicule = 20–22 pm and mucro in both sexes hair brush like. A. pinusi sp.n. (from rhizosphere of Pinus sp.) has females with. L = 0.56–0.80 mm; a = 25–43; b = 9.1–11.6; b′ = 4.0–5.0; c = 12.16; c′ = 3.7–6.9; stylet = 13 μm; V = 65–70; postvulval uterine sac = 34–60 μm long; lateral lines 2; mucro ventral. Males common, dorsal limb of spicule 25–30 μm long, with knob like process at its distal end. A. spinohamautus sp.n. (from mushroom beds) has females with L = 0.63–0.79 mm; a = 31–36; b = 10.3–15.2; b′ = 4.5–7.6; c = 13–17; c′ = 3.5–4.8; stylet= 11–13 μm; V = 69–73; post vulval uterine sac = 61–76 μm; lateral lines 4; mucro spiny with broad base. Males common, dorsal limb of spicule 25–27 μm long, with a knob-like process at the distal end. Twelve known species of the genus collected from Haryana and Himachal Pradcsh have been reported with A. blastophthorus Franklin, 1952 being a new record from India. Compendium and key to Indian species of Aphelenchoides are provided.
