Rock Pools

Here is a new species of Berosus from Venezuela that will appear in a forthcoming paper. It has a very specific habitat: it lives in "pothole" pools in the large granite outcrops in the Guiana Shield region. Despite our sampling efforts, this species has only been found in these pools, where it can be fairly common--but nowhere else...not even in nearby forest pools or ditches! Another example of the high habitat specificity in the region.
