CommentZhao & Adler 1993 cite the source of this species as HU & ZHAO in ZHAO 1972, (Key to Chinese snakes) although Hu et al. 1975 also describe this species as new (in “Three new species of reptiles from Hainan Island”). It’s also described as new in Hu & Zhao 1966 (where other species such as Achalinus meiguensis are described).
