Sucinoptinus undetermined

Sucinoptinus sp.?

M a t e r i a l. Two specimens, SIZK UA-284, Rovno amber, Late Eocene and SIZK K-6067, Klesov, Rovno amber, Late Eocene.

The inclusion labeled UA-284 contains a well recognizable spider beetle belonging to the genus Sucinoptinus sp. The specimen is practically complete except the antennae and parts of the legs, but its orientation in the inclusion makes difficult a specific identification. However, it looks like a S. rovnoensis, but with the typical semicircular depression on the posterior third of the pronotum somewhat deeper, and with the strial punctures of the elytra somewhat broader, which leave the interstriae intervals only slightly wider than the punctures (fig. 1, 3). The specimen SIZK K-6067 is also practically complete, but again the orientation makes difficult a complete identification. It looks very similar to the specimen UA-284, but with the pronotum slightly more transversal and the elytra somewhat shorter (fig. 1, 4).
