It was characterized by the first labial annule wider than the second, fewer body annule numbers(R=39～41), longer stylet (St=80～88μm), Rex=12～14, crenate edge of body annules. Ogma serratum was collected from the soils around roots of Quercus griffithii in Qianshan mountain, Liaoning Province. It was distinguished by one cap～like labial annule, 8～10 rules serrate cuticular ornamentation of body annules, fewer body annules (R=31～36), longer stylet (St=78～98μm), Rex=10～12, Rv=3～5.
