Diagnosis. Species of this subgenus differ from those of the subgenus Hypocaccus chiefly by the almost completely smooth pronotum; occasionally there is fine punctation in the anterior angles.

BOUSQUET & LAPLANTE (2006: 196) state that metatibia is on the outer-lateral margin with at least three rows of denticles, as opposed to two that are present in the subgenus Hypocaccus . However, this character must be verified by further studies based on more material.

Biology and Distribution. Typical littoral taxon, with 13 species and 3 subspecies distributed worldwide on beaches ( MAZUR 1997). Absent in the interior.

Species examined. Hypocaccus (Baeckmanniolus) dimidiatus dimidiatus ( Illiger, 1807) , H. (B.) dimidiatus maritimus ( Stephens, 1830) , H. (B.) varians varians ( Schmidt, 1890) .
