Se describe por primera vez para la flora argentina una especie del género <em>Cyrtopodium, C. paniculatum</em> (Ruiz &amp; Pav.) Garay. Se incluyen sinónimos, observaciones ecológicas y una clave para diferenciarla de las entidades afines. Además se aclara la identidad de <em>C. pflanzii</em>, previamente citada para la Argentina.

Cyrtopodium valebellae, a new species from northwestern Argentina and southwestern Bolivia, is described, illustrated, and compared with morphologically similar taxa. The species is similar to C. virescens in general morphology and flower colour but differs in floral morphology details, particularly in lip morphology and geographic distribution. All known records are from the Southern Andean Yungas and Chaco Serrano ecoregions, indicating that the species is endemic to these regions. Cyrtopodium valebellae has been known since 1965 but has been misidentified so far with C. paniculatum, C. punctatum or C. virescens. The new species was first noticed through photographs available on online biodiversity platforms, highlighting its usefulness as a complementary source of data for discovering new species.
