Diagnosis. Ceraeocercus can be easily distinguished the combination of the following characters: black or brown wings with lighter fenestration, male tenth abdominal tergum with two strongly down-curved broad lobes, bifurcate male cercus, female without bi-concave plate at the base of subgenital plate (from Karabağ 1961).

Redescription. Fastigium of vertex triangular, gradually narrowed towards front, narrower than first antennal segment, dorsally slightly sulcate. Compound eyes nearly hemispherical. Metazona flat, with broadly rounded posterior margin and distinct lateral carina ( Fig. 1d ), and without median line ( Fig. 1c ). Prosternum with a pair of spines. Humeral notch distinct.

Female. Ovipositor slightly shorter than hind femur, regularly down-curved.

Face uniformly whitish, without continued black fascia between compound eyes; areas near compound eyes and antennal sockets black, or blackish-brown in a few individuals; front surface of fastigium of vertex and fastigium of frons same colour as face. Tegmen with irregular blackish and creamy-buff spots.
