The work of taxonomists is often understated if not completely misunderstood. Without taxonomists, organisms cannot be accurately identified, neither can these organisms be given universally accepted names, and reliably positioned in the phylogenetic tree of life. Thanks to the work of taxonomists over the last 269 years since Carl Linnaeus established the binomial system, we can now measure the health and wealth of our biodiversity in a refined, science-based inventory prescribed by stringent nomenclatural rules.展开更多

A key to the three species and illustrations are provided. In addition, Rubus eucalyptus Focke （Rosaceae） is recorded as the host plant ofP. shennongjianus Qin ＆ Huang, sp. nov.展开更多
