Eusphalerum sp. 3 Figures 12, 13, 86, 89

Materials examined.

One male, an inclusion in the same piece of the Baltic amber that contains a specimen of Eu. sp. 2 and Eu. sp. 4, with an additional label: "Eusphalerum sp. 3 | Shavrin A.V. det. 2018" (private collection of Vitaly Alekseev (Kaliningrad, Russia), registered as AWI-045).

Preservation.

The specimen is located dorsolaterally close to the margin of the piece of amber (Figs 12-13). Antennae, lateral potion of the pronotum and elytra with details of the structure of punctation and microsculpture, abdomen and legs (partly) are visible in a dorsal view of the body (Fig. 86); eyes, antennae, some details of thorax, legs and abdomen are relatively visible in a lateral view of the body (Fig. 89).

Remarks.

This specimen is about 2.30 mm long (Figs 86, 89). It is similar to Eu. kanti sp. nov. and Eu. sp. 4 in the shape of the body, eyes and antennomeres. Because some morphological details of head, pronotum, thoracic sclerites, and legs, as well as punctation and microsculpture, are not visible, we leave this specimen unnamed.
