This species is found in southern Yunnan (Hekou and Pingbian) and southern Guangxi (Longzhou) in China and is reportedly widespread throughout Viet Nam (Bourret, 1941; Inger et al., 1999; Orlov et al., 2000), yet recent surveys have only yielded a few specimens (Inger et al., 1999, Nguyen and Bain pers. comm.). Specimens have been collected from southern Lao People's Democratic Republic (Stuart, 1999), and one on the hilltop of Doi Phu Kha, Nan Province, Thailand (T. Chan-ard pers. comm.). The records from central Lao People's Democratic Republic (Stuart, 1999) might be in error (B. Stuart pers. comm.).
