Ectinogonia Spinola 1837 is composed of 22 species to date, but its taxonomic history has been complex and is still unresolved. The species of the Santiagan Province of Central Chile are particularly complex because they show important morphological variability and overlapping traits, making species identification and delimitation difficult. The main goal of the present study is to show the phylogenetic relationships among species of Ectinogonia of the Santiagan province and discuss the taxonomic and systematic implications of our findings. Phylogeny reconstructions as well as a haplotype network disclosed four groups, partially inconsistent with the traditional taxonomy. Actually, the two Ectinogonia speciosa subspecies (E. speciosa speciosa (Germain 1856) and E. speciosa oscuripennis Cobos 1954) belong to two distinct clades, which are not reciprocally monophyletic, meaning that Ectinogonia speciosa is polyphyletic. On the other hand, the two other clades each contain, two nominal species (E. buquetii (Spinola 1837) and E. vidali Moore & Guerrero 2017, and E. isamarae Moore 1994 and E. speciosa oscuripennis Cobos 1954) without reciprocal haplotype sorting. These results suggest that: (1) E. speciosa oscuripennis should be raised to species level and (2) the following new synonymies are proposed: E. isamarae Moore 1994 is synonymised with E. oscuripennis Cobos 1954 and E. vidali Moore & Guerrero 2017 is synonymised with E. buquetii (Spinola 1837).
