Status. Pontocaspian species, identity uncertain.

Type locality. Middle and southern Caspian Sea, 45-81 m.

Distribution. Type locality only.

Taxonomic notes. The species differs from U. ulskii and U. behningi in the very slender elongate shape and the presence of a subsutural band; this suggests P. derzhavini might be likely a member of Caspia s.s. A revision is required to clarify its taxonomic status and generic placement.

Conservation status. Not assessed.
