In their monograph on the Lycaenopsis group of polyommatine genera, Eliot & Kawazoe, 1983, list 14 taxa as valid subspecies names, plus many further synonyms to which they accord lesser status. According to Eliot & Kawazoe, 1983, these 14 subspecies are divided into four groups as follows:
In India, C. argiolus is known as the hill hedge blue. In North America, the ladon group of subspecies are known as the spring azure. Also the name echo blue is used for the C. a. echo western subspecies.
