Macroinvertebrates are used as bioindicators worldwide, but the high diversity ofmacroinvertebrate species and endemism in Latin America (LA) requires greater knowledge ofthis group to increase the effectiveness of biomonitoring. We examined some of the primarytaxonomic and ecological studies on macroinvertebrates in the region, quantified the number ofpapers that used foreign and local indices, examined alternative approaches to bioassessment thatmay be more relevant for the region, and explored freshwater ecosystem management in LA.Here, we highlight the need to increase taxonomic knowledge and the number of specialists inlocal fauna, establish and maintain taxonomic collections in public institutions, and make onlinedatabases on the biodiversity in each country available. However, we also demonstrate thattaxonomy specialists of different nationalities do collaborate on the generation of fundamentalinformation about biodiversity in LA. We found that 57% of the 215 reviewed scientific articlesfrom LA used foreign but locally adapted indices for biomonitoring aquatic ecosystems. Only21% of these articles presented local indices developed in LA. New technologies, such asenvironmental DNA, offer substantial potential for bioassessment but only in regions wheresufficient taxonomic knowledge exists and where species-level stressor–response relationshipsare well described. In the absence of more complete taxonomic records, there could be somevalue in developing biological trait and multimetric indices, and occupancy models could bedeveloped to analyze the relationship between taxa and stress factors. These tools could beadopted by researchers to generate more accurate biotic indices based on local taxa. Finally, inLA, bioindicators are used to support scientific research more often than as environmentalmonitoring tools. Environmental laws and regulations that support the biomonitoring of LAfreshwaters and unified criteria for evaluating and monitoring aquatic ecosystems are essential toface regional and global challenges.
