Type species. Cephalosyne capitata Ponomarenko, 1969 by original designation.

Differential diagnosis. Prosternal process with acute apex, slightly longer than procoxae; anterior process of metaventrite more than two times shorter than mesocoxae.

Revised diagnosis. Small beetles, with elongate, ovoid body. Procoxae strongly transverse. Intercoxal process acute, narrowing apically, distinctly longer than prosternum in front it. Elytra with widely rounded apex, about three times as long as pronotum, with punctate striae. Mesocoxae widely separated, ovoid-transverse. Metaventrite rectangular, very weakly narrowing anteriorly; longitudinal suture distinct, paracoxal suture visible only near posterior angles. Metanepisterna with thick median longitudinal ridges. Visible abdominal sternites not overlapping; apical sternite twice as long as penultimate.

Species included. Monotypic.
