Madelinia gedanoposita Alekseev et Pankowski, 2020

Material examined. One specimen with collection number MMO 1/22 4730/253 [ MWO]; Baltic amber, adult, male, complete specimen with exposed distal part of genitalia and metathoracic wings; specimen partially obscured by layered structure of the amber and milky opacity (forebody). Body length of the specimen is 3.3 mm. The beetle inclusion is preserved in a small-sized, yellow, polished piece of transparent amber with dimensions of 10×6× 5 mm without supplementary fixation. Syninclusions are absent.

Note. The holotype length is 5.8 mm. The second known exemplar of the extinct Madelinia gedanoposita is distinctly smaller than holotype. The size difference between specimens is considered as intraspecific variation of a single species, such size range is normal situation among the related extant beetles.
