6. Bagous exilis group

Diagnosis. Body short and broad-oval, very small (length <2 mm) (Char. 1.1). Forehead between eyes broad. Elytra short, subrectangular, with greatly shortened caudal prolongation (char. 37.1), and lacking declivital callosity (char. 36.0). Scales of elytral intervals arranged in regular pairs, side by side, each interval with two, individually distinct rows of round scales across each interval (char. 41.1). Tibiae with apices only moderately arcuate, lacking denticles; tarsi short, with tarsomere 3 subquadrate and as wide as tarsomere 2. Penis body compressed, dorsoventrally flattened. Median orificial sclerites with upturned Y-shaped process (char. 82.3).

Remarks. This group is formed by three very closely related small-sized Palaearctic species, which are characterized by the lack of declivital callosities and the pattern of the elytral vestiture, which they share with other unrelated groups, and which are differentiated by characters of the male genitalia.
