Diagnosis: Selymbria is characterized by the triangular head in dorsal view, prominent eyes, wider than the lateral angle of the pronotal collar, auxiliary auditory structure absent in males, pygofer with upper lobes, long and undivided uncus, and an aedeagus with a short theca, resembling those in species of Tettigarcta White, 1845 ( Tettigarctidae ) ( Marshall et al., 2018; Sanborn, 2019).
