Elytral margin bearing a series of umbilicate pores, pores denser in preapical and apical part, asymmetrically situated, distances vary between left and right elytron. Left elytron with 5 (6) humeral, 2 (3) medial and 8 subapical pores, right elytron with 6 (7) humeral, 3 medial and 7 (8) subapical pores. Scutellum welldefined, subtriangular, moderately vaulted, parascutellar striae missing. Legs long, lacking any modification.
