Dictyneis is a genus of leaf beetles in the subfamily Eumolpinae. It is endemic to Chile. It is apterous.
The original type species designated for Dictyneis was Myochrous pulvinosus <small>Blanchard, 1851</small>. This species was moved to Glyptoscelis by Jerez and Berti (1987), which would automatically make Dictyneis a synonym of Glyptoscelis. However, Jerez (1991) then designated Myochrous asperatus <small>Blanchard, 1851</small> as the type species, which is considered invalid by Elgueta, Daccordi & Zoia (2017). Despite this, Dictyneis continues to be used, as it is intended that a submission to the ICZN will be made to preserve the name.
