Of these, 997 refer to currently accepted genera, 227 in Dynastinae, 261 in Rutelinae and 509 in Cetoniinae.</span> <span lang="en-US">A further &gt;650 genus-group names are given subgeneric rank or placed in synonymy.</span> <span lang="en-US">The chronology of descriptions of currently valid genera shows similar patterns in each of the three subfamilies with many described in the 1840s, a large group in the late 1800s (especially the Cetoniinae) and early 1900s (Dynastinae and Rutelinae) and a steady increase in numbers following World War 2. We predict that discovery of new genera, as well as the potential for further splitting of mega-genera with elevation of subgenera to full generic level, will continue the upward trend, albeit somewhat balanced by combining the numerous monobasic genera.</span></span></span></span></p> <p> </p> PETER G.
