They decided that about 70 species that they had put in the genus "Hyla" should be in "Boana" instead. Since then, scientists have written reports about many newly discovered "Boana" species.
As of April 2020, there are 95 species of frogs in this genus:

The medal is given yearly and, unlike other Royal Society medals (such as the Hughes), has always been given every year without a break.

The 2020 award was to Ben G. Davis for "inventing powerful chemical methods that... manipulate complex biological molecules" (etc).
