A new species and a key to Isomira Mulsant, 1856 (Coleoptera: Tenebrionidae: Alleculinae) from Eocene Baltic amber Author Nabozhenko, M. V.

Monotypic genus. Type stratum. Omine , Japan , Hazegatani coal mine, Monomoki Formation , Carnian , Upper Triassic (235–221.5 Ma) . This genus was originally included under question in the family Tenebrionidae . Fujiyama [1973] tried to compare the single elytron of M. minensis with those in Menephilus Mulsant, 1854 (Stenochiinae: Cnodalonini) and Tenebrio Linnaeus, 1758 (Tenebrioninae: Tenebrionini). In fact, the elytron of this species has 10 striae without scutellary striole, which is uncharacteristic for Tenebrionidae . Menephiloides minensis specially was not included in the fossil records [Kirejtshuk at al., 2008; Kirejtshuk, Ponomarenko, 2018 ; Nabozhenko, 2019]. However Bao and Antunes-Carvalho [2020] still wrote that it is Tenebrionidae . Here we propose to interpret Menephiloides minensis as Coleoptera incertae sedis .
