Update checklist of family Baetidae from Venezuela

The first and only known checklist of Ephemeroptera from Venezuela was published by Chacón et al. (2009), who reported six species of baetids assigned to three genera ( Baetodes , Camelobaetidius , and Cloeodes ). This paper formally updates the checklist by Chacón et al. (2009) for the family Baetidae and adds new information to the list of Ephemeroptera species in South America ( Dominguez et al. 2022). Thus, the records of the family Baetidae from Venezuela increased to 16 genera and 30 species (Tab. 1).

In this study the presence of Camelobaetidius patricki is reported for the first time in the country, which increases the number of baetid species to 30. Currently, in Venezuela, the number of species of the family Baetidae is higher than that for Leptophlebiidae species; being the latter the most diverse family in the Neotropics. This is probably due as a result of major taxonomic and sampling efforts in some bioregions such as Guayana and the Cordillera de la Costa. However, even all through the knowledge of the Venezuelan biodiversity of Baetidae has increased in the last 10 years; greater sampling efforts seem to be required in other bioregions. Therefore, the updated check list indicates that it is necessary to continue research in the following unexplored bioregions: Insular [ INSU], Depresión del Lago de Maracaibo [ DLMA], Sistemas de Colinas Lara-Falcón [ SCLF], Costera Continental [ COSC], and Deltaica del RÍo Orinoco [ DROR].
