Subfamily ENDOMYCHINAE Leach, 1815

Remarks. The beetle specimen from amber piece No. 1222-5 possesses characters of the subfamily Endomychinae (according to Robertson et al., 2015, this subfamily includes now Endomychus Panzer, 1795 and all genera previously classified in the subfamily Stenotarsinae), such as: body densely pubescent (glabrous in most species of Endomychus); pronotum with broad lateral, raised margins (except for Saula Gerstaecker, 1858 and Endomychus); head without occipital file and antennal grooves; anterior margin of pronotum without stridulatory membrane; tarsi pseudotrimerous with lobed tarsomere 1 and 2; and mesocoxal cavities open laterally (Tomaszewska, 2000; Robertson et al., 2015). Therefore we assign it to the subfamily Endomychinae .
