Splendeuptychia ackeryi, the Magdalena Valley ringlet, is a species of butterfly first classified in 2009.

[1] The specimen was initially collected in the dry Magdalena River Valley of Colombia by Blanca Huertas.

The females are almost identical to males, but forewings (FW) are more rounded and with paler ground colour.

The name ackeryi is formed as the genitive singular of a fictional second declension masculine Latin noun.

The epithet is dedicated to Phil Ackery, former Collections Manager of Lepidoptera at the Natural History Museum where he worked for more than 35 years.
