Echinoderms in Argentina are closely associated with the pioneering studies of Irene Bernasconi, particularly regarding sea cucumbers from the collection at the Museo Argentino de Ciencias Naturales “Bernardino Rivadavia” (MACN). The Holothuroidea class comprises 325 lots from various global regions, as recorded in the MACN invertebrates collection (MACN-In). This study analyses all specimens from shallow waters of Argentina and includes detailed information on species distribution, depth range, and remarks for each species, along with a key for identification. We identified 19 out of 26 species known to inhabit Argentina, representing 73% of the recorded species. The absence of certain specimens may stem from challenges in sampling, restricted distributions, or past misidentifications in literature. This research enhances our understanding of Argentina’s biological diversity. Future studies aim to build on this foundation and continue the legacy initiated by Bernasconi.
