Abstract

Liparthrum squamosum Blackman (Coleoptera: Curculionidae: Scolytinae: Hypoborini) is reported for the first time from Pennsylvania. A single specimen was found in 2015 and four subsequent specimens were collected in 2024 through several insect trap and lure combinations. These records increase the known range for this species in the eastern United States.
