The genus records of adult aquatic Coleoptera of the family Elmidae, generated by 30 macroinvertebrate assessments of Colombian runningwaters, were evaluated against the background of taxonomic literature used for identification and by means of zoogeographical plausibilitychecks. Around 42% of the reported genera and 15% of the overall genus records turned out to be presumably erroneous, attributing 12 Nearcticgenera and one Old World genus to the Colombian elmid fauna. The total of misleading generic identifications is assumed to be much higherand turned out to be generally induced by common appliance of taxonomic identification keys not suitable for taxonomic treatment of theNeotropical fauna. On the other hand, an existing appropriate key to South American genera (Manzo 2005) was found to have rarely been used.Some supplementary notes to this key are given, together with general recommendations for coherent genus determination of Elmidae from the Neotropical realm, and an updated checklist of New World genera and their principal distribution areas.
