Updated catalog of the Chilean wedge-shaped beetles (Coleoptera: Ripiphoridae) with the first records of Macrosiagon flavipennis (LeConte) in Chile

The biology and ecology of wedge-shaped beetles (Coleoptera: Ripiphoridae) are scarcely known in the Neotropical realm. Chilean species of this beetle family are currently represented by two genera: MacrosiagonHentz, 1830 and RipiphorusBosc, 1791, and three species, only known from their type localities. Here, we present an updated catalog of Chilean Ripiphoridae, along with the new distributional and biology records. Also, Macrosiagon flavipennisLeConte, 1866 (Ripiphorinae: Macrosiagonini) has been reported for the first time in Chile. We discuss the reasons for the presence of M. flavipennis in urban areas, the state of knowledge of the endemic species presents in Chile in relation to their distribution and the opportunity to use opportunistic records to better understand their natural history.
