Genus Pseudolepturges Gilmour (1957) (Coleoptera: Cerambycidae: Lamiinae): a new species from Bolivia, key to the species of the genus and first reports of a possible Pseudomyrmex ant mimic in longhorn beetles

A new species of Pseudolepturges from Bolivia is described and illustrated; a key to the species is also provided. Based on the similar body size, orange-yellowish colour, behaviour, and close co-occurrence on a Triplaris americana tree, we suggest that Pseudolepturges triplarinus sp. nov. is a mimic of the ant Pseudomyrmex triplarinus. http://www.zoobank.org/urn:lsid:zoobank.org:pub:6DF38C64-6986-4A79-8D9A-645DA89149F2
