Male pygofer lobe with articulated dorsal appendage, with or without ventral appendage, with one or more dorsal macrosetae, basolateral setae in distinct group, small or distinctly enlarged. Subgenital plate with 2 or more macrosetae in oblique row or 3 macrosetae forming triangle at some distance from base and numerous short stout setae on outer lateral margin. Style with apex variable in shape. Connective U- or Y-shaped, with or without central lobe. Aedeagal shaft tubular, usually with 1 or more processes; gonopore apical or subapical, usually on ventral or caudal surface. Anal tube process present or absent.

Notes: Although many of the mentioned structures are variable within the genus, Salka can be distinguished from other Erythroneurini by the following combination of characters: color pattern brown; vertex with dark median apical spot; pygofer not extended to apex of subgenital plate, with one or two dorsal macrosetae, basolateral setae in distinct group; pygofer dorsal appendage movably articulated.

Distribution. Oriental and southern Palearctic regions.
