The newly described fossil taxon shares the characters of the tribe Hypulini within Melandryinae : procoxae contiguous, pretarsal claws simple, antennae 11-segmented and filiform, base of pronotum closely associated with elytral base, head well visible from above, elytra narrowly ovate, elytral punctuation irregular, lateral edges of pronotum not fully margined, penultimate tarsomere of all legs bilobed etc. The studied amber specimen is assigned to Madelinia as it shares a set of characters diagnostic for this genus: scutellar shield visible, pronotal base distinctly margined, pronotum with distinct basal triangular depressions, pronotal base slightly narrower than elytral base, pronotum laterally margined in basal one-third, elytra uniformly dark colored, and metatarsomere 1 not shorter than one-half of metatibia.
