Koch Liston (2012) described an argid sawfly from South Africa and named it Arge davidi Koch Liston, 2012. Shinohara Hara (2017) very recently described another argid from Taiwan under the same name, Arge davidi Shinohara Hara, 2017. The latter authors simply overlooked Koch Liston's (2012) taxon and Arge davidi Shinohara Hara, 2017, is a primary junior homonym of Arge davidi Koch Liston, 2012.
