Pronotal disc with sharp longitudinal costa attached to middle of anterior margin. Scutellum simply rounded posteriorly. Elytra very slender, flat, each elytron with three longitudinal costae. Costa 1 inconspicuous in apical part. Male genitalia slender, internal sac sclerotized, complex, lower plate relatively small ( Fig. 14 ).
