D64E5474FF8FEE42FFD8FA9AA955F988.taxon	etymology	Etymology: Named after the country of origin. Diagnostic characters: The new species can easily be separated from its congeners by having a superior volsella that is sharply bent medially and a parallel-sided anal point. The species is small, with a wing length of about 1.3 mm and an antennal ration (AR) of about 0.3.	en	Andersen, Trond (2018): A new species of Claudiotendipes Andersen, Mendes & Pinho, 2017 from Bolivia (Diptera, Chironomidae).
