Subfossil remains of Camptocercus lilljeborgii were abundant in the sediments of a core taken from a presently paludified shore of Lake Väike Juusa, southern Estonia. This made it possible to identify and describe the subfossil remains of the taxon, especially headshields and shells. The remains resemble those of Camptocercus rectirostris but differ in details that make the identification easy. The headshield is stouter and more arched and has no surface sculpture. It can also be distinguished from headshields of Camptocercus fennicus and Acroperus harpae by shape. The shell is characterized by parallel blurred lines and teeth on the posterior-ventral angle. The postabdomen is elongate and narrow and has more than 20 teeth on the dorsal margins.
