Ingrischgryllacris Cadena-Castañeda n. gen.

Diagnosis: Small size for the family (15–17 mm) ( Figs. 121, 122, 130 ). Head with inconspicuous ocelli, space between antennal sockets two times as wide as antennal scape ( Figs. 123, 124 ); fore coxa without spine, slender legs wit five pairs of movable spines on fore and middle tibiae (spines moderately developed), with four mid sized spines on ventral edge of hind femora ( Fig. 125 ) and rather numerous small unarticulated spines on hind tibiae. Apterus, abdomen without traces of femoro-abdominal apparatus; 9 th tergite covered the 10 th and with posterior edge rounded ( Figs. 126–129 ), 10 th tergite short and moderately bilobated and with a central sclerozed hook ( Fig. 127 ); epiproctus prolongated and triquete, projecting between of the subgenital plate notch ( Figs. 126, 128 ); cerci thin and without modifications; subgenital plate rectangular and shorth with a wide notch, styles cylindrical and dilated from base to apex and up curved in lateral view (very similar to Glaphyrosoma paraprocts (Neotropical Anostostomatidae )) ( Figs. 126, 127, 129 ). Female abdomen without specialized tergites ( Fig. 130 ); ovipositor as long as a half of hind femur curved upwards and with sharp apex ( Fig. 130 ).

Type species: Ingrischgryllacris brevifalcatus ( Brunner von Wattenwyl, 1888) n. comb.

Etymology: Dedicated to Sigfrid Ingrisch as a recognition to his contributions to Orthoptera and for his collobarations to this paper with his photos from several specimens of the German collections (DORSA project); plus typical termination— gryllacris common to genera of this family.

Comparision: This new genus differs from all other genera of the tribe for its specialized male terminalia and sharp ovipositor, the other Ametroidini not have that modifications.

Distribution: Cammeroon and Ghana (West–Central Tropical Africa).
