Number: 492, Pages: 1 - 14
Two new species, Plagiolepis chomphuphuangi sp. n. and Plagiolepis silpaarchai sp. n., are described based on the worker caste from Laos and Thailand, respectively. The type series of former species was collected on the ground in a coffee plantation at highland (ca. 1000 m). Plagiolepis silpaarchai sp. n. inhabits lowland (ca. 250 m), and the type series was collected with a pitfall trap in a disturbed area near a mixed deciduous forest during the dry season. A key to the Southeast Asian species of the genus Plagiolepis Mayr, 1861 is provided.
