Subfamily PLEGANOPHORINAE Jacqueline du Val, 1858

Remarks. Beetle specimens from amber pieces No. 1506-1 and No. 53-2 possess characters of the endomychid subfamily Pleganophorinae, such as: body usually pubescent; tarsi 4-segmented, simple; antenna composed of 4–5 antennomeres with the terminal antennomere modified/enlarged (Tomaszewska 2000, Robertson et al. 2015). Therefore, we assign them to this subfamily.
