The new world tropics continue to be a rich source of species discovery. Today’s issue of Zootaxa contains a monograph by Rodrigo Feitosa and Beto Brandão revising the ant genus Lachnomyrmex, a small yet delightfully wrinkled group of soil-dwelling ants. Of the 16 species recognized in the new paper, ten were previously unknown. For the mathematically-challenged, that’s more than half.
Lachnomyrmex amazonicus, pictured above, is one of the new species. It has been recorded from lowland humid forests in the states of Amazonas, Para, and Mato Grosso.
