Abstract
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, 1830Hentz, N.M. 1830. Remarks on the use of the maxillae in Coleopterous insects, with an account of two species of the family Telephoridas, and of three of the family Mordellids, which ought to be the type of two distinct genera.

(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.
