During the survey of plant parasitic nematode of Citrus orchard in Korea, Paratrichodorus minor (Colbran, 1956) Siddiqi is founded from the soil of Citrus unshiu Markovich for the first time in Korea. The body length of females is $428.34{\sim}506.22{\mu}m$ long: a = $12.08{\sim}22.79$, b = $4.02{\sim}5.02$, V(%) = $38.46{\sim}60.68$. The excretory pore is located near the base of esophagus. Additionally, the morphological characteristics on P. porosus (Allen, 1957) Siddiqi, 1974 recorded in 1976 on Korea is redescribed in detail.
