Description of the larva of Indocnemis orang (F?rster in Laidlaw, 1907) (Odonata: Platycnemididae: Calicnemiinae) from Thailand, with larval key to the known genera of the family Platycnemididae in Asia

摘要

The larval characters of the genus Indocnemis Laidlaw, 1917 are described based on larval specimens of I. orang (F?rster in Laidlaw, 1907) from Thailand. The larvae are characterized by 5-6 pairs of premental setae, 8-9 palpal setae of the same length, and vertical lamella caudal gills. The habitats and new provincial records of I. orang in Thailand are also provided in addition to a key to the genera of the family Platycnemididae in Asia.
