The latest ZooKeys issue is out. It is a monograph (Review of the Berosus of Venezuela with description of fourteen new species) on water scavenger beetles. The reviewed genus is the largest of the family, with 273 species distributed worldwide.

It is also one of the most commonly collected groups of water scavenger beetles in the world as well as one of the most recognizable, due to their typical “hunchbacked” appearance. All known species are aquatic, and generally good swimmers. They inhabit a range of “traditional” aquatic habitats, with most species occurring in ponds and marshes.

In the present work, the total number of species known from Venezuela is raised from 9 to 36, including the description of 14 new species. That is twice the entire number of species that are known from all of North America.
