Current status. Synonym of Dactylispa (s. str.) sauteri Uhmann, 1927 .

Remarks. Gressitt (1939a) described it as a distinct species and compared to D. pugnax (Gestro, 1897) . Later on, Gressitt (1950) downgraded its rank to subspecies of D. sauteri without any additional comments. Chen et al. (1986) considered the taxon as plain synonym of D. sauteri . It differs from typical D. sauteri in shorter spines but their position is exactly the same and by presence of indistinct dark brown patches on the apical half of the elytra near the apical margin. These characters are in our opinion fully within variability of D. sauteri and we agree with the synonymy.
