The first description of the larva of Neoperla gordonae Stark, 1983 and redescription of Cryptoperla meo Stark, 1989 from Huai Nam Dung National Park, Thailand

Abstract

The larva of Neoperla gordonae Stark, 1983 has not been described in previous studies, and some characteristics of Cryptoperla meo Stark, 1989 in the larva stage do not resemble the previous descriptions. Therefore, the purpose of this study was to describe the morphological characteristics of the larva stage of Neoperla gordonae and Cryptoperla meo from Huai Nam Dung National Park, Thailand. The larvae of Neoperla gordonae were collected from two streams of Huai Nam Dung National Park: Huai Hea and Mae Yen Streams, whereas the larvae of Cryptoperla meo were collected from three streams: Nam Dung, Mae Jok, and Mae Ping Streams. The larvae of the two species were reared and emerged in the laboratory, that both larvae and adults could be used for the purpose of identification.
