| Rhytidodus decimusquartus (Schrank) is the only representative of the subfamily Idiocerinae in Argentina, which inhabits on "poplars" in the western part of Mendoza, Neuquén and Río Negro provinces. In this contribution, we provide a detailed morphological redescription of this species for easy identification from material collected in Argentina; some characters of the female genitalia are described for the first time. Additionally, new records from the southeastern region of this country are provided. |
