title: Possible living fossil in Bolivia: A new genus of flea beetles with modified hind legs (Coleoptera, Chrysomelidae, Galerucinae, Alticini).
abstract: A new genus (Chanealtica) with three new species (Chanealtica cuevas, Chanealtica ellimon, and Chanealtica maxi) from Bolivia is described and illustrated. It is compared with Aphthonoides Jacoby, 1885, Argopistes Motschulsky, 1860, Metroserrapha Bechyne, 1958, Psylliodes Berthold, 1827 and Psyllototus Nadein, 2010. Remarkably, based on the available characters, among all the flea beetles, Chanealtica is mostly similar to an extinct genus Psyllototus. A discussion of diversity and function of the hind leg in flea beetles is provided.
