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

Based on a single well-preserved specimen from Eocene Baltic amber, a new comb-clawed beetle Isomira lobanovi sp. n. (Alleculinae: Alleculini: Gonoderina) is described and illustrated. The new species belongs to the subgenus Mucheimira Novák, 2016, with extant species distributed in South China, Him...

The new species belongs to the subgenus Mucheimira Novák, 2016, with extant species distributed in South China, Himalaya and the south of Arabian Peninsula. Isomira lobanovi sp. n. is the most similar to I. (Mucheimira) avula Seidlitz, 1896 from Baltic amber, but differs from the latter by the following characters: antennae longer, distinctly moderately serrate; antennomere 11 clearly longer than antennomere 10; antennomere 3 with sharply obliquely truncate apical margin.
