Description of three new species of Benedictus (Coleoptera, Chrysomelidae, Galerucinae, Alticini) from China, with comments on their biology and modified ethanol traps for collecting flea beetles

The diversity and biology of the moss and leaf litter-inhabiting flea beetles are still poorly known. In this study, three new species of Benedictus are described from China: Benedictusfuanensis Ruan & Konstantinov, sp. nov., Benedictusquadrimaculatus Ruan & Konstantinov, sp. nov., and Bened...

Sumario:The diversity and biology of the moss and leaf litter-inhabiting flea beetles are still poorly known. In this study, three new species of Benedictus are described from China: Benedictusfuanensis Ruan & Konstantinov, sp. nov., Benedictusquadrimaculatus Ruan & Konstantinov, sp. nov., and Benedictuswangi Ruan & Konstantinov, sp. nov. Comments on their biology are given. Benedictusquadrimaculatus has a highly unusual morphological feature not reported before in flea beetles: black spots on the abdominal tergites that are visible through the elytra. Traditional and modified ethanol traps were tested and proven useful for collecting leaf litter- and moss-inhabiting flea beetles. Based on our tests, eight traps could collect one specimen each day in the testing sites in Fujian Province; three traps could collect one specimen each day in the testing sites in Guangdong Province.
