This work describes the new genus Parasynneuria gen. nov. and its species type P. anae Parra sp. nov. An approach using geometric morphometrics method was used to describe wing shape morphotypes and variation of the specimens studied in their distributional range in Chile. Wing shape differences were quantified in P. anae by means of geometric morphometric tools. This species is geographically distributed in the south of Chile, with individuals present in Concepción, Maullín, Valdivia and Chiloé provinces from where specimens were sampled to model the morphological variation of the wing in the species. The results show significant differences in the multivariate analysis of the wing shape. Phenotypic variations may potentially be environmentally plastic.
