Coloration variability of the Oriental genus Agnorimus Miyake Iwase, 1991 (Coleoptera: Scarabaeidae, Cetoniinae) with synonymic notes

摘要

Based on an examination of a large number of specimens, considerable variability of the elytral coloration patterns and the parameres of the Asian genus Agnorimus Miyake Iwase, 1991 are observed; and the taxonomic status of all four described taxa have been re-considered. The result shows that only A. pictus (Moser, 1902) can be recognized as valid species, while A. hayashii Miyake Iwase, 1991 new synonym is proposed as a new junior synonym of it. The geographic distribution of this genus is significantly expanded, and most of the distributional records are illustrated in a map with intraspecific variations indicated.
