The Hymenoptera (ants, bees and wasps) are one of the most species rich and diverse groups of living organisms on the planet.
Within insects, the order is probably rivalled in size only by the Diptera (flies), either group almost certainly more speciose than any other order, including the Coleoptera (beetles).
The neotropical region is one of the least studied parts of the world, yet it is likely to be the most species rich. To date about 35,000 species have been catalogued for the region with the total number of species likely to be well in excess of ten times that number.
The order includes species that exhibit virtually all lifestyles found in insects and many have a direct impact on biodiversity and the well-being of humans as well as other animals.
We publish original, large, high-quality monographs on the taxonomy of Neotropical Hymenoptera.
The journal provides a low-cost, rapid vehicle for describing the huge diversity of this order in the region. Publications are Open Access as PDF/A, completely ICZN (International Code of Zoological Nomenclature) compliant and free to authors.
Printed version of each contribution can be made available at the author’s expense.
