Zopheromimus auriborussiensis Alekseev et Nabozhenko, 2023

( Figs 42–44 )

Material examined. One specimen with collection number JDC-11965 [ JDC], Baltic amber; adult, sex unknown. A complete beetle is included in a transparent, yellow amber piece with dimensions of 20× 17 mm and a maximum thickness of 5 mm, preserved without supplementary fixation. Syninclusions: absent.

Note. Body length of beetle JDC-11965 (including visible part of head) 4.9 mm. This specimen has 5-5-4 tarsal formula, protruding hemispherical eyes, and 11-segmented antennae with weakly developed 2-segmented club. Specimen JDC-11965 shares with the holotype of Z. auriborussiensis other external characters and is considered conspecific. The smaller body size (4.9 mm in contrast to 5.3 mm in the holotype) is interpreted as intraspecific variability.
