Taxonomy

Acanthopsoides was first formally proposed as a monospecific genus in 1934 by the American zoologist Henry Weed Fowler with Acanthopsoides gracilis as its only species, as well as being designated as its type species.^[1] The type locality for A. gracilis was given as Chiang Mai in the Chao Phraya River basin of Thailand.^[2] This taxon was thought to be a synonym of Aperioptus, a genus proposed by Sir John Richardson in 1848 for Aperioptus pictorius, however, the specimens Richardson used to describe the genus were lost. In 2015 a neotype of Aperioptus pictorius was designated, but this designation was considered invalid and the next available name, Acanthopsoides, was put forward.^[3] This genus is included in the family Cobitidae, the true or spined loaches, in the suborder Cobitoidei of the order Cypriniformes.^[4]
