Bukejs, Andris, HAEva, Jiří & Alekseev, Vitalii I., 2020, A new fossil species of Attagenus Latreille (Coleoptera: Dermestidae) in Rovno and Baltic ambers, with a brief review of known fossil beetles from the Rovno amber Lagerstätte, Fossil Record 23 (1), pp. 95-104 : 96

Subgenus Aethriostoma Motschulsky, 1858

Remarks

The studied amber beetles show the combination of characters unequivocally corresponding to Attagenini within Attageninae : prosternum not forming “collar”, mouthparts free, antennal club with three compact antennomeres, abdomen with five visible ventrites and elytra not shortened.

The specimens considered here were assigned to the subgenus Aethriostoma within Attagenus based on the combination of the following characters: (1) disc of metaventrite nearly twice as wide as long and (2) body strongly convex and widely oval (in Attagenus s. str. disc of metaventrite nearly twice as long as wide, and body less convex and more narrowly obovate).
