Distribution of Agapetus spp. in Thailand

Sixteen species of Agapetus including the new species are now recorded from Thailand ( Figs 2A–2D ). Most of our country’s Agapetus spp. have been reported from northern Thailand. Agapetus halong is a widespread species which is found from northern Thailand through western Thailand, northeastern Thailand, and the Thai Peninsula, and this species is recorded also from Vietnam, which is in the same Indochinese sub-region of the Oriental Region ( Armitage et al. 2005; Malicky 2010). Agapetus dangorum is also a widespread species which is found from northern Thailand through the Thai Peninsula and also has been recorded from Vietnam ( Armitage et al. 2005; Malicky 2010). However, this species has not been recorded from the Malay Peninsula ( Malicky 2010). Agapetus gotgian and A. gonophorus also inhabit both northern Thailand and Vietnam ( Malicky 2010; Armitage et al. 2005). Recently a collection of caddisflies from hill evergreen forest in Tai Rom Yen National Park demonstrated that A. viricatus , previously known only from northern Thailand, was found in southern Thailand where the elevation is 900–1200 m a.s.l. Nine species of Agapetus spp. are endemic, having been reported from only northern Thailand (Indochinese sub-region), including A. abdeel , A. atuus , A. esinertus , A. lalus , A. phorkys , A. quordus , A. seheliel , A. vercondarius , and A. voccus . Insofar as we know, the new species A. kaengkrungensis is endemic to southern Thailand which is in the Sundaic sub-region of the Oriental Region.
