Alethaxius
Alethaxius is a genus of leaf beetles in the subfamily Eumolpinae. It is distributed from Mexico to northern South America, and it is also found in the West Indies. The genus was originally named "Aletes" by Félicien Chapuis in 1874. However, this name was preoccupied by "Aletes" Carpenter, 1857 (in Mollusca), so the genus was renamed to "Alethaxius" by Édouard Lefèvre in 1885. According to Flowers (1996), it is very likely that "Alethaxius" is polyphyletic and represents at least three different genera. Synonyms:
