Satyrium latior is a butterfly of the subfamily Lycaeninae. It was described by Johann Heinrich Fixsen in 1887. It is found in the Russian Far East (Transbaikalia, Amur, Ussuri), northern China and Korea.[1]
The larvae feed on Rhamnus davurica, Rhamnus ussuriensis and Armeniaca sibirica.
latior Fixs. (72 h) is one-third larger [than ''[[Satyrium spini|spini]]], with the colour darker and more intense, the scaling being so dense that the scent-patch of the male is hardly visible; from the Amur, Corea, and North China.[2]
