Genus Sanaa Walker, 1870

Type species. -

Sanaa regalis (Brunner von Wattenwyl, 1895)

Comparison with congeners. -

There are two other species of Sanaa , both reported from the Indomalaya region: S. intermedia Beier, 1944, originally reported from Than-Moi, Vietnam, and S. imperialis (White, 1846), originally reported from Sylhet, Bangladesh ( Orthoptera Species File Version 5.0/5.0). The latter species, however, is also recorded from Nepal ( Beier 1962). The female of S. regalis differs from that of S. imperialis mainly in having its ovipositor black at the base, while the ovipositor of S. imperialis is yellow ( Barman 2003). Similarly, the ovipositor of S. Sanaa intermedia is yellow-brown at the base ( Beier 1962).
