46FC58C7148A566E8C27FE7D37840A91.taxon	etymology	Etymology. Philibaetis is an arbitrary combination of letters with allusion to the Philippines, where the genus occurs and to the genus Baetis. The latter is with reference to the superficial similarities between both genera and the fact that the species of Philibaetis gen. nov. were up to now assigned to Baetis. Gender is masculine.	en	Kaltenbach, Thomas, Garces, Jhoana M., Gattolliat, Jean-Luc (2021): Philibaetis gen. nov., a new genus from the Philippines (Ephemeroptera, Baetidae).
