Material examined. Indonesia: Sulawesi, 1871, leg. A.B. Meyer— 1 male (holotype) (Dresden SMTD) .

Diagnosis. Species of Celebogryllacris are similar to those of Aphanogryllacris but have the male eighth abdominal tergite considerably prolonged and the ninth tergite has the dorsal area strongly shortened and the descending area is pointing somewhat anteriorly that gives the impression as though the ninth tergite lies on the underside of the eight tergite. The strong medial furrow of the ninth tergite and the resulting lateral lobes that are prolonged into a pair of apical processes C. helleri shares with Aphanogryllacris . The longer tegmina in C. helleri have a free and undivided media anterior while in A. inconspicua it has a common base with CuA. The media posterior in C. helleri arises from CuA 1 in subbasal area of tegmen at end of the curvature that follows the separation of CuA1 from CuA2. A unique feature of Celebogryllacris is the cylindrical process of the female seventh abdominal sternite.
