Invertebrate Taxonomy and Ecology

We present a preliminary list of the immature Ephemeroptera genera for Tolima region. These results come from the studies made in ten areas (Cajamarca, Chaparral, Coello, Cunday, Dolores, IbaguA©, Prado, Rio Blanco, Rovira and Villa Rica) between 2002 and 2008. A total of 10,235 identified organisms are listed here, all of which reside in the “ColecciA³n ZoolA³gica de la Universidad del Tolima, SecciA³n Macroinvertebrados AcuAiticos (CZUT-MA)”. Seven families and 41 genera are registered for Tolima region, being the 78 % and 95 % of the total families and genera registered for Colombia. The most widely distributed family of the order was Baetidae, and the least was Euthyplociidae. Baetodes , Thraulodes , and Leptohyphes had the best distribution inside the region, also being the most abundant ones. These results, allow us to deduce that Tolima region holds an immense Ephemeroptera diversity, which makes it necessary to perform more studies in order to complete the limited taxonomic, ecological and applied knowledge of the order we have today.
